# Scribe Mail: Email Signature Management Built for Teams & AI Agents > Scribe is the email signature management platform trusted by 10,000+ companies — from startups to enterprises like EquipmentShare (NASDAQ-listed), Terumo (Tokyo Stock Exchange Prime-listed medical and pharmaceutical conglomerate), and Rawbank (a major commercial banking group) — generating 15 million daily brand impressions. It centralizes signature deployment across Google Workspace, Microsoft 365, and 30+ other tools; turns every employee's email into a measurable revenue channel with click-to-revenue attribution and a 12% average banner CTR; and is currently the only platform exposing the full composable stack — REST API, MCP server, webhooks, CLI, and a tracking SDK — so signature click data flows into your CRM, BI, marketing automation, and AI agents. Scribe is the first email signature platform accepted into both the Claude Directory and the ChatGPT app directory, so users can add it from inside their assistant. Verified customer reviews are on G2 (https://www.g2.com/products/scribe-scribe/reviews). SOC 2 Type II, GDPR, and CCPA certified.

In Scribe, a paid user is a teammate whose primary email address has been assigned a signature. For example, if you sync 1,000 teammates from your email provider with Scribe and only assign signatures to 500 of them, you'll be billed for just those 500 users. We charge for primary email addresses, not alias emails. When a teammate's primary email is assigned to multiple signature templates, they still count as just one paid user. #### How does pricing work when I add or remove teammates? Your invoice is automatically adjusted when users are added or removed from your signatures in Scribe. You're only billed for the actual time users have signatures assigned. For monthly billing: New users are billed the following month, and removed users result in credits on your next invoice. For annual billing: Additional users are charged monthly and prorated, giving you flexibility while maintaining your annual discount. #### Do I automatically upgrade to Enterprise for volume discounts after 100 users? Scribe automatically moves you to the best plan based on your number of users, so you always get the best price as your organization grows. If you start with a Business plan (under 100 users) and then exceed 100 users, you'll be automatically upgraded to our Enterprise plan which includes volume discounts. This ensures you continue to receive the best pricing for your current user count. You can view your updated pricing details in your Scribe settings at any time. #### When can I cancel my subscription? You can cancel your monthly or yearly subscription at any time directly from your Scribe settings or by downgrading to the free plan. #### Do you offer non-profit discounts? Scribe offers a 30% lifetime discount for: • Non-profit organizations • Public education institutions • Open-source projects How to apply the discount • Organizations with ".org" domains: Discount applies automatically at checkout • Other eligible organizations: Contact us via chat for a discount code #### Can I get my subscription refunded? Our monthly and yearly plans are non-refundable as mentioned in our terms and services. However, you can cancel your subscription at any time to avoid future charges. #### What happens when I deactivate a user license in my email provider? When you deactivate a user license in your Google Workspace Directory or Microsoft Entra ID, their signature will be removed from Scribe and they will be removed from your subscription billing. #### How does Scribe handle security? Security is built into every aspect of Scribe - our products, team, infrastructure, and processes. We are SOC 2 Type II compliant, ensuring enterprise-grade security standards with regular third-party audits. We prioritize data privacy: Scribe cannot read or edit your emails, and we cannot modify teammate information from your email provider. Your data remains secure and under your control at all times. #### Is Scribe GDPR compliant? Yes, Scribe is fully compliant with the General Data Protection Regulation (GDPR). GDPR requires businesses to protect the personal data and privacy of EU citizens. Under GDPR, EU citizens have the right to: • Request all information a company has collected about them • Request deletion of their personal data from company systems and sub-processors If you wish to exercise these rights regarding data that Scribe and its sub-processors have collected, please contact us at hello@scribe-mail.com. Our GDPR certification is available upon request. #### Does Scribe have a carbon removal program? Yes, Scribe contributes 1% of your subscription revenue to remove CO2 from the atmosphere through Stripe Climate, helping fight climate change. ### About Scribe Source: https://www.scribe-mail.com/about #### What is Scribe? Scribe is an email signature management platform for teams and AI agents. Companies use it to centrally design, deploy, and update branded email signatures across Google Workspace, Microsoft 365, Apple Mail, and 30+ connected tools, and to turn signatures into a measurable marketing channel with banner campaigns and click-to-revenue attribution. #### Is Scribe the same as ScribeHow or the Scribe documentation tool? No. Scribe at scribe-mail.com is the email signature management platform, built by Scribe SAS. It is unrelated to Scribe at scribehow.com / scribe.com (an AI process-documentation tool), Scribe Media (book publishing), the Scribe markup language, transcription services, or medical scribe services. #### Who makes Scribe? Scribe is built by Scribe SAS, a French software company founded in 2020. The product is distributed directly at scribe-mail.com and through the Google Workspace Marketplace and Microsoft AppSource. #### Which email platforms does Scribe support? Scribe deploys signatures to Google Workspace, Microsoft 365 (Outlook desktop, web, and mobile), Apple Mail, and server-side rewriting for inboxes that bypass client-side installation. It also connects to 30+ tools (HRIS systems, business phone providers, calendars, and sales execution platforms) to keep signature data live. #### Is Scribe secure and compliant? Yes. Scribe is SOC 2 Type II certified and GDPR and CCPA compliant. Security architecture, certifications, and audit details are published at security.scribe-mail.com. #### Can AI agents manage Scribe? Yes. Scribe exposes the full composable stack: a hosted MCP server at mcp.scribe-mail.com/mcp with OAuth sign-in (no API key needed), a REST API, AI skills, webhooks, a CLI, and a tracking SDK. Scribe is listed in the Claude Directory (as Scribe Mail) and the ChatGPT app directory, so Claude and ChatGPT add it in one click; Cursor and any other MCP client connect to the server directly. Assistants can then build, audit, and report on email signatures in plain English. ### AI agents Source: https://www.scribe-mail.com/ai-agents #### What is the Scribe MCP server and how do I set it up? The Scribe MCP server is a hosted endpoint that connects your AI assistant to your Scribe account. Claude and ChatGPT users add it in one click from the Claude Directory or the ChatGPT app directory. Any other MCP client connects to https://mcp.scribe-mail.com/mcp. Either way you sign in with your Scribe account, then manage your email signatures by chatting in plain English. #### How do I connect Claude or ChatGPT to Scribe? In Claude, open the Scribe Mail listing in the Claude Directory and click Connect to Claude. In ChatGPT, open the Scribe listing in the ChatGPT app directory and click Install. Both sign in with your Scribe account through OAuth, with no API key and no Developer Mode. Step-by-step guides for Claude, ChatGPT, Cursor, and more are in the Scribe help center. #### Is Scribe listed in the Claude and ChatGPT app directories? Yes. Scribe is published in the Claude Directory as Scribe Mail (claude.ai/directory/scribe-mail) and in the ChatGPT app directory as Scribe, the first email signature platform in either. You connect or install it from inside your assistant instead of pasting a connector URL, and it signs in with OAuth, so there is no API key. #### Which AI assistants work with Scribe? Scribe works with Claude, ChatGPT, Cursor, and other assistants that support the Model Context Protocol (MCP). Chat assistants let you manage signatures in plain English. Coding assistants can build on the Scribe API and MCP, or run the Scribe CLI as a local MCP server. #### Is there a Scribe CLI? Yes. The Scribe CLI (@scribemail/cli on npm) puts every Scribe tool in your terminal. Sign in once with scribe login, run commands like scribe signatures list, or start a local MCP server with scribe mcp for Claude Code, Claude Desktop, Cursor, and any stdio MCP client. #### Do I need an API key or any code to use Scribe with my AI assistant? No. You connect with a single sign-in and Scribe never stores an API key in your assistant. Everyday tasks are done by chatting, so no code is required. #### Can my AI assistant change my signatures without my approval? No. Reports and lookups run automatically, but any change, such as creating, updating, or publishing a signature, asks for your confirmation first. The assistant acts as you, in your workspace only. #### What can an AI assistant do with my Scribe account? You can ask it to design and publish signature templates, audit install and compliance status, look up teammates and smart field data, set up workspaces, track campaign performance, rank signatures by clickthrough rate, and export engagement data. #### Is my data safe when I connect an AI assistant to Scribe? Yes. Connecting authenticates the assistant as you, inside your workspace only. Scribe uses OAuth, so no API key is stored in the assistant, and every change is confirmed before it happens. ### Scribe MCP server Source: https://www.scribe-mail.com/mcp #### What is the Scribe MCP server? It's a hosted endpoint that connects your AI assistant to your Scribe account, so you can manage email signatures by chatting. It lives at mcp.scribe-mail.com/mcp and works with any MCP client. #### How do I set up the Scribe MCP server? In Claude, open the Scribe Mail listing in the Claude Directory and click Connect to Claude. In ChatGPT, open the Scribe listing in the ChatGPT app directory and click Install. Any other MCP client adds the connector at mcp.scribe-mail.com/mcp. In every case you sign in with your Scribe account, with no API key to paste. Guides for Cursor, Codex, Copilot, and more are in the help center. #### Is the Scribe MCP server in the Claude Directory and the ChatGPT app store? Yes. Scribe is the first email signature platform listed in both: as Scribe Mail in the Claude Directory (claude.ai/directory/scribe-mail) and as Scribe in the ChatGPT app directory. Both listings run on the same hosted MCP server. #### Do I need an API key to use the Scribe MCP server? No. The connection uses OAuth sign-in. You only need a Scribe API key if you build directly against the REST API in your own app. #### Which AI assistants work with the Scribe MCP server? Claude and ChatGPT install it from their app directories. Cursor, Codex, Claude Code, Microsoft Copilot, Gemini Enterprise, Grok, Mistral, and any other client that supports the Model Context Protocol connect to mcp.scribe-mail.com/mcp. #### Can I run the Scribe MCP server locally? Yes. The Scribe CLI (@scribemail/cli on npm) serves the exact same tools as the hosted server over stdio: run scribe login once, then scribe mcp for Claude Code, Claude Desktop, Cursor, or any local agent that can launch a command. #### What can I do through the Scribe MCP server? Create and publish signatures, audit installs, manage teammates and smart fields, run campaigns, pull analytics, and read your plan and invoices. #### Can the assistant change my account without my approval? No. Reports and lookups run automatically, but any change is confirmed first. The connector acts as you, in your workspace only. #### Is the Scribe MCP server free? The Scribe MCP server is available to every Scribe workspace — connect any MCP-capable assistant and sign in. Read actions run automatically and every change is confirmed first. ### Email signature MCP server Source: https://www.scribe-mail.com/email-signature-mcp-server #### What is an email signature MCP server? It is a Model Context Protocol server that connects an AI assistant to an email signature platform. The assistant can then list, create, publish, and assign signatures, update teammate data, run banner campaigns, and report on clicks by calling the server's tools, so you manage signatures by chatting instead of clicking through an admin console. #### How is an email signature MCP server different from an API? A REST API is built for developers: you write code and manage an API key. An MCP server describes the same operations as tools an AI assistant can discover and call on its own, so anyone can use them in plain English. Scribe offers both, and its MCP server runs on the same REST API. #### Which AI assistants work with an email signature MCP server? Any assistant that supports MCP. With Scribe, Claude and ChatGPT install it from their app directories, and Microsoft Copilot, Gemini, Grok, Mistral, Cursor, Codex, and Claude Code connect to https://mcp.scribe-mail.com/mcp. #### Is it secure? What permissions does it have? The Scribe MCP server signs you in with OAuth, so no API key is stored in your assistant. It acts as you, in your own workspace only. Read actions like listing and reporting run directly, and every write, such as creating, updating, publishing, or deleting, asks for your confirmation first. Scribe is SOC 2 Type II, GDPR, and CCPA certified. #### Do I need a developer to set it up? No. In Claude or ChatGPT you add Scribe from the app directory and sign in. Other assistants take one connector URL. Developers who want scripts or a local server can use the Scribe CLI or the REST API, but neither is required. #### Which email signature tools have an MCP server? Scribe offers a hosted, official MCP server, listed in the Claude Directory, the ChatGPT app directory, and the official MCP Registry. Based on public documentation in October 2026, SyncSignature also offers a hosted MCP server and Signitic offers a read-only one. We found no public MCP server from Exclaimer, CodeTwo, Letsignit, WiseStamp, Rocketseed, Opensense, or Xink. #### What can I ask an email signature MCP server to do? With Scribe: audit which signatures are published and who has them, find teammates missing a title or phone number, update their details, assign signatures to directory groups, schedule, pause, and resume banner campaigns, and rank signatures by views, clicks, and clickthrough rate. #### Is the Scribe MCP server included in my plan? The Scribe MCP server is available to every Scribe workspace. Connect any MCP-capable assistant and sign in with your Scribe account. ### Scribe AI agent Source: https://www.scribe-mail.com/scribe-ai-agent #### What is the Scribe AI agent? The Scribe AI agent is the assistant built into the Scribe email signature platform. It answers questions about Scribe from the help center, reads your workspace to answer questions about it, builds signatures in the editor, and makes the changes you approve. Open it with the Ask AI button or ⌘J (Ctrl+J on Windows). #### What can the Scribe AI agent do? With your approval, it creates, edits, duplicates, and deletes signatures and their variants, chooses who gets a signature, then publishes and installs it, adds and syncs teammates, manages smart fields, folders, and media library images, and creates, schedules, pauses, and resumes campaigns. It also opens the right page or setting when you ask. #### Can the Scribe AI agent change my workspace without my approval? No. Outside the editor, every change shows an approval card in plain words, and nothing happens until you click Yes, do it. In the signature editor it edits the draft in front of you, every change can be undone, and it never publishes: you do. #### What does the Scribe AI agent never do? It never changes your billing or plan, deletes your workspace, manages members or their roles, sets up SSO or domains, sends invitations or notifications to your teammates, or deletes in bulk. When you ask for one of these, it takes you to the right page or to our support team. #### Who can use the Scribe AI agent? The owners and admins of a workspace on the Business and Enterprise plans, and during the 14-day free trial. People with the Member role don't see the Ask AI button. It works in the Scribe web app, not in the desktop app or the Outlook add-in. #### Which AI model powers the Scribe AI agent, and is my data used for training? Answers are written by Anthropic's Claude. Anthropic is one of Scribe's subprocessors and doesn't use your conversations to train its models, and neither does Scribe. A conversation is private to you and deleted 90 days after its last message. #### How is the Scribe AI agent different from the Scribe MCP server? The Scribe AI agent lives inside the Scribe web app, with nothing to connect. The Scribe MCP server brings Scribe to the AI assistant you already use, like Claude, ChatGPT, or Cursor, so you can manage signatures from there. ### REST API Source: https://www.scribe-mail.com/api #### What is the Scribe API? It's a REST API to manage email signatures, teammates, smart fields, folders, assets, and marketing campaigns. Requests and responses use JSON over HTTPS, it's versioned under /v1, and the base URL is https://api.scribe-mail.com/v1. #### What can I build with the Scribe API? Create, publish, install, and assign signatures, manage teammates and their smart fields, organize folders and assets, and schedule banner campaigns. Anything you can do by hand in the dashboard, you can automate. #### How do I authenticate with the Scribe API? Send a workspace API key as a Bearer token: Authorization: Bearer YOUR_API_KEY. A key acts as the member who created it, within one workspace, and can be scoped to specific resources. #### Does Scribe have an MCP server too? Yes. The MCP server lets AI assistants manage your account by chatting, using OAuth with no API key. It is listed in the Claude Directory and the ChatGPT app directory, and any MCP client can connect to it. The REST API is for building Scribe directly into your own app with an API key. Many teams use both. #### Is there a Scribe CLI? Yes. Install it with npm install -g @scribemail/cli, then run scribe login to sign in with your browser, with no API key. Every API resource is a subcommand with JSON output, like scribe signatures list or scribe campaigns schedule, and scribe mcp serves the same tools to a local AI agent over MCP. #### How are pagination and errors handled? List endpoints return results in pages, with a pagination object on every response. Errors use standard HTTP status codes and a consistent JSON error envelope. #### Is the Scribe API versioned? Yes. The version is part of the path, under /v1. New, backward-compatible fields can be added within v1 without breaking your integration. ### Webhooks Source: https://www.scribe-mail.com/webhooks #### What are Scribe webhooks? Scribe webhooks send a signed HTTPS POST request to your endpoint every time something happens in your email signature workspace: a conversion is recorded, a visitor is identified, a signature is published or fails to install, a teammate is added or removed, a campaign changes state, or an integration is connected or loses access. You react to events instead of polling the API. #### Which email signature events can I subscribe to? conversion.recorded, visitor.identified, signature.published, signature.installation.failed, teammate.created, teammate.deleted, campaign.scheduled, campaign.started, campaign.paused, campaign.resumed, campaign.ended, integration.connected, integration.access_lost, and integration.disconnected. Subscribe each endpoint to the events it needs, or to all of them. #### How do I set up a Scribe webhook? In the Scribe dashboard, open Settings, then Webhooks, and click Manage webhooks. Add your HTTPS endpoint URL, pick the event types, and send a test delivery. The same portal shows delivery logs, replays failed deliveries, and rotates signing secrets. #### Do I need to build a server to receive Scribe webhooks? No. Any HTTPS URL works, including the catch hook URL from Zapier, Make, or n8n. Build your own endpoint when you need signature verification and full control over retries, which anything that writes to a system of record deserves. #### How do I verify that a webhook comes from Scribe? Every delivery carries svix-id, svix-timestamp, and svix-signature headers. Scribe webhooks are powered by Svix and follow the Standard Webhooks signing scheme, so an official Svix library verifies them in one call with the signing secret shown in the webhook portal. #### What happens if my endpoint is down? Nothing is lost. Failed deliveries are retried automatically with exponential backoff for about a day. Once your endpoint is healthy, replay the missed deliveries from the webhook portal. Delivery is at least once, so deduplicate on the svix-id header. #### Which plans include Scribe webhooks? Webhooks are part of the Scribe API, included in the Business and Enterprise plans and in the 14-day free trial. Workspace owners and admins manage the endpoints. ### CLI Source: https://www.scribe-mail.com/cli #### What is the Scribe CLI? The Scribe CLI (@scribemail/cli on npm) is a command line tool to manage email signatures, teammates, smart fields, campaigns, and analytics from your terminal. Every Scribe tool is a subcommand with JSON output, and scribe mcp serves the same tools to a local AI agent over MCP. #### How do I install the Scribe CLI? Run npm install -g @scribemail/cli with Node.js 20 or newer, then scribe login to sign in with your browser and scribe whoami to check the session. #### Do I need an API key to use the Scribe CLI? No. scribe login signs you in with your Scribe account in the browser. Credentials are stored on your machine with owner-only permissions and refresh automatically. Over SSH, run scribe login --no-browser and open the printed URL locally. #### Can I use the Scribe CLI with Claude Code or Cursor? Yes. Run claude mcp add --scope user scribe -- scribe mcp for Claude Code. For Claude Desktop, Cursor, and other clients configured in JSON, add a server with the command scribe and the argument mcp. The agent then calls every Scribe tool as you. #### What is the difference between the Scribe CLI and the Scribe MCP server? They share the same tools. The hosted MCP server at mcp.scribe-mail.com/mcp is the right choice for chat assistants like Claude and ChatGPT. The CLI runs on your machine, for scripts, for agents that only speak stdio, and for tool calls that run as your signed-in terminal session. #### Is the Scribe CLI open source? Yes. It is published under the MIT license, with its code, releases, and issues on GitHub at github.com/scribemail/cli. #### Which plans include the Scribe CLI? The CLI is part of the Scribe API, included in the Business and Enterprise plans and in the 14-day free trial. The signed-in member must be a workspace owner or admin. ### Agent skills Source: https://www.scribe-mail.com/skills #### What is the Scribe skill? It's a SKILL.md file that teaches your AI assistant the full Scribe workflow, so it creates, publishes, and audits email signatures in the fewest steps. It works alongside the Scribe MCP server. #### What's the difference between the skill and the MCP server? The MCP server gives your assistant the tools to act on your Scribe account. The skill is the know-how to use those tools well: which call to make first, how to build a valid signature, and when to publish. Use them together. #### Which assistants support the Scribe skill? Any assistant that supports skills, including Claude Code, Cursor, and Codex. For chat assistants like Claude and ChatGPT, paste the skill into your project or conversation. #### How do I add the Scribe skill? Add the SKILL.md file to your coding assistant, or paste it into your chat assistant. Then connect the Scribe MCP server, in one click from the Claude Directory or the ChatGPT app directory, or at mcp.scribe-mail.com/mcp for any other MCP client, and start asking in plain English. #### Do I need the skill to use Scribe with my assistant? No. Your assistant can use the Scribe MCP server on its own. The skill makes it faster and more reliable, especially when building a signature from scratch. #### Is the skill safe? Yes. The skill only guides how your assistant uses Scribe. Every change still asks for your confirmation, and everything stays inside your workspace. ### Email signature ROI calculator Source: https://www.scribe-mail.com/roi-calculator #### How is email signature ROI measured? Email signature ROI is measured along two axes: revenue generated and time saved. On the revenue side, it's the value of leads and customers your team's signatures bring in, typically calculated as total emails sent × signature banner click-through rate × landing page conversion rate × average customer value. On the time side, it's the hours your team gets back when signatures are managed centrally instead of one inbox at a time, multiplied by your team's hourly cost. A complete ROI calculation subtracts the cost of the signature platform from both gains. The calculator above models both with sensible defaults you can adjust for your team. #### What's a good click-through rate for signature banners? Across 50,000+ emails sent through Scribe, signature banners average a 12% click-through rate, roughly 6× higher than typical email marketing. Two things drive the gap. First, signature emails are one-to-one and already opened. Someone is reading a real, individual message directed at them, not scanning a marketing blast. Second, the banner sits inside a message the recipient is actively engaged with, not previewed and discarded. Anything above 8% is healthy. Below 4% usually points to a mismatch: wrong audience, weak offer, or a destination that doesn't follow through on the click. #### How does Scribe track conversions from signatures? When someone clicks a link in a Scribe signature, we append a unique click ID called sclid to the destination URL, similar to Google's gclid or Meta's fbclid. A lightweight tracking SDK on your website (under 3KB, installable without a developer) stores that ID in a first-party cookie. When the visitor completes an action you've defined (demo booked, signup, purchase), the SDK reports it back, and Scribe attributes the conversion to the specific signature, banner, campaign, and teammate that generated the click. For purchase or subscription events where accuracy matters most, you can also send conversions server-side via the API. Attribution uses last-touch within a 30-day window. Full setup details are in the conversion tracking docs. #### How long does it take to see ROI from a signature platform? Most teams see measurable returns within the first month. Time savings start the moment automated deployment is live, usually within a day of setup. There's no waiting period: every signature update from that point forward bypasses manual installation entirely. Revenue attribution takes slightly longer because it depends on your sales cycle. For self-serve products with short cycles, conversions can show up in the first week of running a banner. For longer B2B cycles, click-to-conversion data populates as deals progress, but you'll see leads attributed back to specific signatures and teammates from day one. ### Scribe vs CodeTwo Source: https://www.scribe-mail.com/compare/codetwo #### What is the best CodeTwo alternative? If you need Google Workspace support, conversion analytics or an API, Scribe is built for that. Exclaimer and Letsignit also cover Microsoft 365 and Google Workspace. See the full comparison of CodeTwo alternatives at scribe-mail.com/compare/codetwo-alternatives. #### Does CodeTwo work with Google Workspace? No. CodeTwo Email Signatures 365 is built for Microsoft 365 and Office 365. Scribe supports Google Workspace and Microsoft 365 from one workspace, so mixed environments can share templates and campaigns. #### How much does CodeTwo cost compared to Scribe? CodeTwo has one plan: $1.36 per user per month at 10 users, falling to $0.81 at 500 users on monthly billing, about 10% less yearly, with a 10-license minimum. Scribe is free for 2 users and costs about $2.32 per user per month at 50 users billed yearly; 100+ users get an Enterprise quote. CodeTwo is cheaper on list price. #### Does CodeTwo have an API? CodeTwo does not document a public API for its email signature product. Scribe has a public REST API, webhooks, a CLI and an MCP server for AI assistants. #### How long does it take to switch from CodeTwo to Scribe? Most teams connect Microsoft 365 and publish a first Scribe signature in under 30 minutes. A full switch with a pilot group typically takes 1 to 7 days. #### How much does Scribe cost? Scribe is free for up to 2 users. The Business plan covers 3 to 99 users: $116 per month for 50 users billed yearly, or $145 billed monthly. From 100 users, the Enterprise plan is quoted per organization with volume discounts, SSO and audit logs. Prices are on scribe-mail.com/pricing. #### Does Scribe work with Microsoft 365 and Google Workspace? Yes. Scribe installs signatures client-side in Gmail and Outlook, so people see them while composing, and offers server-side installation for both platforms when you need every mobile app covered. Teammates sync from Entra ID, Google Workspace Directory or Okta. Zoho Mail is supported client-side. Exchange Server on-premises is not supported. #### Can I test Scribe before leaving CodeTwo? Yes. The 14-day trial includes every feature and unlimited users, with no credit card. You can run it on a pilot group while CodeTwo keeps serving everyone else, then switch when you are ready. ### Best CodeTwo alternatives Source: https://www.scribe-mail.com/compare/codetwo-alternatives #### What are the best CodeTwo alternatives in 2026? The most common CodeTwo alternatives are Scribe (Google Workspace and Microsoft 365, conversion analytics, API and MCP), Exclaimer (Microsoft 365, Google Workspace and Exchange), Letsignit (add-in deployment with A/B-tested campaigns), WiseStamp (small teams), Opensense (account-based banners), Xink (low-cost, directory-driven) and Rocketseed (managed server-side setup). #### What is the best CodeTwo alternative for Google Workspace? CodeTwo Email Signatures 365 is built for Microsoft 365 only. Scribe, Exclaimer, Letsignit, WiseStamp, Opensense, Xink and Rocketseed all support Google Workspace. Scribe and Exclaimer manage Google Workspace and Microsoft 365 from one account, which suits companies running both. #### What is the cheapest CodeTwo alternative? On published list prices, Xink (about $0.55 to $1.10 per user per month up to 300 users) and Exclaimer Starter ($0.90 per user per month, billed annually) are in the same range as CodeTwo ($0.81 to $1.36). Rocketseed works out at about $1.02 to $1.18 per user per month for 50 to 200 users, plus a setup fee. #### Which CodeTwo alternative has an API? Scribe has a public REST API, webhooks, a CLI and a hosted MCP server for AI assistants. Xink documents a REST API, and Letsignit has a public API for retrieving signatures. CodeTwo does not document a public API for its signature product. #### Is Scribe cheaper than CodeTwo? Not on list price. Scribe costs about $2.32 per user per month at 50 users billed yearly, against $0.81 to $1.36 for CodeTwo.

Index: https://www.scribe-mail.com/handbook ### Signatures for Replies, Internal Emails, Aliases and Shared Mailboxes: An IT Admin Guide (2026) Source: https://www.scribe-mail.com/en-US/handbook/shared-mailbox-alias-reply-signatures Topic: Rollout Published: 2026-10-24 How to give replies, internal emails, aliases and shared mailboxes the right signature: which deployment methods apply variants and how context is detected, sending from aliases in Exchange Online and Gmail, shared mailbox permissions, multiple signatures per address, licensing and a test matrix. > **TL;DR:** One signature for every situation is too heavy for replies and too external for colleagues. Scribe gives each signature a Primary design plus optional On-Reply and Internal variants, applied by the Outlook add-in and by server-side routing in Microsoft 365 and Google Workspace, but not by the client-side Gmail install. Server-side, a subject starting with Re:, Fw: or Fwd: means reply, and all recipients on the sender's domain means internal. Aliases can each have their own signature at no extra cost, chosen by the From address; Microsoft 365 needs sending from aliases enabled and Gmail needs each alias added as "Send mail as". Microsoft 365 shared mailboxes can be imported from Entra ID and given their own signature; on Google Workspace, a shared address is added as an alias for each person who sends from it. A seat is a person whose primary email has a signature; aliases are free. *Last reviewed: October 2026. Covers Scribe signature variants, email aliases (Exchange Online proxy addresses and Google Workspace alternate addresses) and Microsoft 365 shared mailboxes.* This guide covers the four situations where "one signature per person" stops working: replies and forwards, internal email, sending from an alias such as sales@ or a second domain, and team mailboxes such as support@. It is written for admins setting the rules, so it explains what each mail platform does natively, what the signature tool decides, which combinations are documented, and which ones you should test before promising them to anyone. Licensing comes at the end. ### Why do new emails, replies and internal emails need different signatures? A full external signature (photo, title, phone numbers, social icons, banner, disclaimer) earns its space on the first message to a prospect. On the fifth reply in a thread it is clutter, and in a message to a colleague the banner is advertising to your own staff. Three designs cover most companies: | Context | Purpose | Typical content | | --- | --- | --- | | Primary (new email) | Introduce the sender and the brand | Name, title, company, phones, logo, social icons, banner, legal text | | On-reply (replies and forwards) | Keep the thread readable | Name, title, one phone number, legal text; no banner or photo | | Internal | Identify the sender to colleagues | Name, title, department, internal extension | This is close to Scribe's own suggested setup: a full primary signature with the campaign banner, a shorter on-reply variant without the banner, and a minimal internal variant with name and title ([Signature variants](https://help.scribe-mail.com/en/signature-variants)). One adjustment for regulated industries: keep the legal disclaimer in the reply variant. Replies go to external recipients too, and a confidentiality notice or regulatory statement is usually required on those messages as well. The [email disclaimers guide](https://www.scribe-mail.com/en-US/handbook/email-disclaimers) covers wording. ### Which deployment methods apply reply and internal variants? Variants depend on how the signature is installed. Scribe documents three cases ([Signature variants](https://help.scribe-mail.com/en/signature-variants)): | Deployment | Variants applied? | How the context is decided | | --- | --- | --- | | Microsoft 365 add-in (Outlook) | Yes | Outlook has three signature slots, Primary, Reply and Internal, which Scribe fills ([Teammate profile](https://help.scribe-mail.com/en/teammates/teammate-profile)) | | Server-side, Microsoft 365 or Google Workspace | Yes | Per message, as Scribe processes it (rules below) | | Client-side Gmail (Google Workspace app) | No | Gmail settings hold a single signature per address, with no variant per context | For server-side routing, Scribe states the rules it applies to each message ([Microsoft 365 server side](https://help.scribe-mail.com/en/integrations/signatures/microsoft-365-server-side), [Google Workspace server side](https://help.scribe-mail.com/en/integrations/signatures/google-workspace-server-side)): - **On-reply** when the subject starts with a reply or forward prefix such as `Re:`, `Fw:` or `Fwd:`, including localized equivalents. - **Internal** when every recipient is on the same domain as the sender. - **Primary** in every other case. Read those rules carefully, because they have edge cases worth knowing: - "Internal" is domain-based. Mail from `acme.com` to a colleague at a sister domain such as `acme.co.uk` gets the primary signature. - One external recipient on the line makes the whole message external. - A reply whose subject someone retyped without the prefix is treated as a new email. If Google Workspace is your platform and replies matter, that is a reason to add server-side routing; the [Google Workspace guide](https://www.scribe-mail.com/en-US/handbook/google-workspace-email-signatures) covers setup. Variants are a paid feature, not on the free plan ([pricing](https://www.scribe-mail.com/en-US/pricing)). ### How do you set up reply and internal variants? 1. Open the signature and go to the **Variants** tab. 2. Set **Activate On-Reply signature** and/or **Activate Internal signature** to **Yes**. With No, that context uses the primary signature. 3. From the **⋯** menu on a variant card, choose **Edit Variant** to design it independently, or **Reset to Primary Signature** to start over from the primary design. 4. Decide per variant whether the marketing campaign appears, with its own **Activate Marketing Campaign** toggle. 5. Check all three contexts in **Preview Signatures**, which has Primary, Reply and Internal tabs. Steps are from [Signature variants](https://help.scribe-mail.com/en/signature-variants) and [Preview signatures](https://help.scribe-mail.com/en/preview-signatures). Variants are managed per signature, so a company with ten department signatures has up to thirty designs to keep aligned. Two ways to keep that under control: start each variant from **Reset to Primary Signature** and remove blocks rather than designing from scratch, and script it. The API can list a signature's variants, upsert one, publish it, or reset it to the primary ([API reference](https://help.scribe-mail.com/api-reference/signatures/list-a-signatures-replyinternal-variants)), and the `signature.published` webhook reports which kind was published: `primary`, `reply_variant` or `internal_variant` ([Webhook events](https://help.scribe-mail.com/webhooks/events)). ### How do signatures work with aliases and send-as addresses? An alias is a second address on the same mailbox: `jane@company.com` also receiving `sales@company.com` or `jane@company.de`. Two separate things have to be true for an alias to carry its own signature: the mail platform must let the person send as that alias, and the signature tool must know which signature belongs to it. #### On the Scribe side - Each teammate has one signature for their primary email and can have unlimited alias signatures. Scribe charges per user, not per signature, so aliases cost nothing extra ([Aliases](https://help.scribe-mail.com/en/how-do-scribe-email-signatures-work-with-email-aliases)). - Aliases are imported automatically from Google Workspace or Entra ID when **Import email aliases** is on; you choose which verified domains to include ([Connect Entra ID](https://help.scribe-mail.com/en/teammates/connect-microsoft-entra-id), [Google Workspace directory](https://help.scribe-mail.com/en/editor/google-workspace-directory)). For manually managed teammates, use **Add an email alias** on the profile. - Assign a signature to the alias like any address. The right one appears based on the From address the person selects, in Gmail or Outlook ([Aliases](https://help.scribe-mail.com/en/how-do-scribe-email-signatures-work-with-email-aliases)). - The teammate table expands to show install status per address, including aliases, and can be filtered by "with aliases" ([Assign teammates](https://help.scribe-mail.com/en/assign-teammates-to-a-signature)). - Alias signatures are a paid-plan feature ([pricing](https://www.scribe-mail.com/en-US/pricing)). #### Microsoft 365: let people send from aliases In Exchange Online, extra addresses on a mailbox are **proxy addresses**; mail sent to them is delivered to the primary mailbox ([Microsoft Learn](https://learn.microsoft.com/en-us/exchange/recipients-in-exchange-online/manage-user-mailboxes/add-or-remove-email-addresses)). Sending *from* them is off by default: unless `SendFromAliasEnabled` is `$true`, aliases on sent and received messages are rewritten to the primary address. With it on, compatible Outlook clients can send from and reply to aliases ([Set-OrganizationConfig, Microsoft Learn](https://learn.microsoft.com/en-us/powershell/module/exchangepowershell/set-organizationconfig?view=exchange-ps)). ``` Connect-ExchangeOnline Get-OrganizationConfig | Format-List SendFromAliasEnabled Set-OrganizationConfig -SendFromAliasEnabled $true ``` Microsoft notes the setting affects all messages sent and received by every mailbox, so announce it before you flip it. #### Google Workspace: add the alias as "Send mail as" A Google Workspace admin can add up to 30 alternate addresses per user at no cost, but to send from one the user must set it up as a custom From address in Gmail, and that step isn't visible in the Admin console ([Google Workspace Admin Help](https://support.google.com/a/answer/33327), [Gmail Help](https://support.google.com/mail/answer/22370)). That missing step is the cause of Scribe's most common alias error. If the alias exists only at the admin level, Google's API returns **User not found on Google Workspace** when Scribe tries to install its signature, and the status shows Failed. The fix: the user (or an admin acting for them) opens Gmail **Settings > See all settings > Accounts**, adds the alias under **Send mail as**, verifies it, and Scribe pushes the signature again ([Fix the user not found error for email aliases](https://help.scribe-mail.com/en/troubleshooting/fix-user-not-found-error-for-email-aliases)). In a large rollout, filter teammates by "with aliases" and installation "Failed" to find every case at once. ### How do shared mailboxes and team inboxes get signatures? #### Microsoft 365 shared mailboxes A shared mailbox is a mailbox several people use, such as support@ or info@. It needs no license up to 50 GB, it has an underlying account that shouldn't be signed into directly, and users send from it with one of two permissions ([About shared mailboxes](https://learn.microsoft.com/en-us/microsoft-365/admin/email/about-shared-mailboxes), [Manage permissions for recipients](https://learn.microsoft.com/en-us/exchange/recipients-in-exchange-online/manage-permissions-for-recipients)): | Permission | What the recipient sees | Signature implication | | --- | --- | --- | | Send As | The mail appears to come from the mailbox, with no indication of the delegate | A team signature (team name, team phone) makes sense; a personal name may still be wanted | | Send on Behalf | "Delegate on behalf of Mailbox"; replies go to the mailbox | The sender is visible, so a team signature plus the person's name is consistent | | Full Access | Can open and manage the mailbox but not send from it | None on its own | In Scribe, **Import shared mailboxes** is on by default when you connect Entra ID, and imported shared mailboxes can be assigned signatures like any address ([Connect Entra ID](https://help.scribe-mail.com/en/teammates/connect-microsoft-entra-id)). The website pricing table lists shared mailbox signatures on every plan, including Free ([pricing](https://www.scribe-mail.com/en-US/pricing)); the help center's plans page labels the feature "Microsoft users only" ([Plans](https://help.scribe-mail.com/en/plans)). Both the Outlook add-in and server-side installation apply the shared mailbox's signature when someone sends from the shared mailbox ([Aliases and shared mailboxes](https://help.scribe-mail.com/en/how-do-scribe-email-signatures-work-with-email-aliases)). Still include a send-as and a send-on-behalf test from each client in your pilot. #### Google Workspace team addresses Google Workspace has no direct equivalent of a shared mailbox. Teams use an alias on one person's account (one user per alias; Google recommends delegation when several people need the same address), Gmail delegation, or a Google Group as a collaborative inbox ([Google Workspace Admin Help](https://support.google.com/a/answer/33327), [Gmail delegation](https://support.google.com/a/answer/7223765)). Scribe has no shared-mailbox import for Google Workspace: add the team address as an alias on each person who sends from it, and make sure each of them also has it as a Send mail as address in Gmail, or the install fails with User not found ([Aliases and shared mailboxes](https://help.scribe-mail.com/en/how-do-scribe-email-signatures-work-with-email-aliases)). Scribe doesn't document signatures for delegated mailboxes or Google Groups, so test those before planning on them. #### Team inboxes in Front If support or sales replies from a shared inbox tool, the signature has to be installed there. Scribe has a [Front integration](https://www.scribe-mail.com/en-US/integrations/front), where shared mailboxes also get their signature, matches teammates to Front users by exact email address, and notes that Front can hold more than one signature per email ([User not found on Front](https://help.scribe-mail.com/en/troubleshooting/user-not-found), [Installation statuses](https://help.scribe-mail.com/en/signature-installation-statuses-and-errors)). ### What happens when one address has several signatures? Most integrations install one signature per email address. If someone is assigned more than one, only the highest-priority signature is installed and the others show **Not supported**; this is expected, not an error. Front and Zoho Mail can install more than one per email ([Installation statuses](https://help.scribe-mail.com/en/signature-installation-statuses-and-errors)). For Outlook users, **Signature priority** sets the order, and position 1 becomes the default; it doesn't apply to Gmail, where each teammate gets a single signature ([Signature priority](https://help.scribe-mail.com/en/signature-priority)). The practical rule: give each address exactly one signature, and use variants for context and aliases for roles, rather than assigning several signatures to one address and relying on priority. ### What counts as a paid seat? From Scribe's pricing and plan pages ([pricing](https://www.scribe-mail.com/en-US/pricing), [Plan limits](https://help.scribe-mail.com/en/plan-limits-and-changes)): - A seat is a person whose **primary** email has at least one signature assigned. - Alias addresses don't count as seats and are free. - A primary email assigned to several signature templates still counts as one user. - Syncing people doesn't bill them: sync 1,000 and assign signatures to 500, and you pay for 500. - Deactivating a user's license in Google Workspace or Entra ID removes their signature and their seat. Scribe's docs don't state whether a Microsoft 365 shared mailbox with a signature counts as a seat. Shared mailboxes have their own account in Entra ID, so ask Scribe before budgeting a large number of them. ### How do you test replies, aliases and shared mailboxes before rollout? | Scenario | Expected result | | --- | --- | | New email to an external address | Primary signature | | Reply and forward to an external address | On-reply variant (Outlook add-in or server-side); primary on client-side Gmail | | New email to a colleague on the same domain | Internal variant (Outlook add-in or server-side) | | Email to a colleague and an external recipient together | Primary (server-side rule: not every recipient is internal) | | Email to a colleague on a sister domain | Primary (server-side rule is domain-based) | | Send from an alias in Outlook and in Gmail | The alias's signature; the From address stays the alias | | Send As and Send on Behalf from a shared mailbox | The shared mailbox's signature on each client you support | | Long thread with ten replies | One signature per message, no stacking | Use Scribe's preview tabs to check designs first, then send real mail and check it in the recipient's mailbox. With server-side routing the sender's Sent Items copy doesn't show the signature ([Scribe docs](https://help.scribe-mail.com/en/integrations/signatures/microsoft-365-server-side)). The wider pilot plan is in the [rollout playbook](https://www.scribe-mail.com/en-US/handbook/email-signature-rollout-playbook). ### Where does Scribe fit? Scribe handles the cases in this guide from one dashboard: reply and internal variants with their own campaign switches, unlimited free alias signatures imported from the directory, shared mailbox import from [Entra ID](https://www.scribe-mail.com/en-US/integrations/microsoft-entra-id), and install status per address. Variants work through the [Microsoft 365 add-in](https://www.scribe-mail.com/en-US/integrations/microsoft-365) and [Microsoft 365](https://www.scribe-mail.com/en-US/integrations/microsoft-365-server-side) or [Google Workspace](https://www.scribe-mail.com/en-US/integrations/google-workspace-server-side) server-side routing, and can be managed through the [API](https://www.scribe-mail.com/en-US/api) as well as the editor. ### Frequently asked questions #### Can I use a different email signature for replies? Yes. In Scribe each signature can have an On-Reply variant, typically a shorter design without the banner or photo. It is applied by the Microsoft 365 Outlook add-in and by server-side routing in Microsoft 365 and Google Workspace. The client-side Gmail install writes a single signature into Gmail settings, so it doesn't apply variants. #### How does a signature tool know an email is internal? With Scribe's server-side routing, a message is internal when every recipient is on the same domain as the sender, and a reply when the subject starts with a prefix such as Re:, Fw: or Fwd:, including localized ones. Everything else gets the primary signature, so a message with one external recipient, or to a sister domain, is treated as external. #### Should the reply signature keep the legal disclaimer? In most regulated organizations, yes. Replies reach external recipients just like new emails, so confidentiality or regulatory text that must appear on external mail belongs in the reply variant too. Drop the banner and photo instead. #### Can each email alias have its own signature? Yes. Scribe allows one signature for the primary address and unlimited alias signatures per person, and the signature is chosen by the From address. Aliases are imported from Google Workspace or Entra ID. In Microsoft 365, SendFromAliasEnabled must be on for users to send from aliases; in Gmail, each alias must be added as a Send mail as address. #### Why does Scribe show User not found for a Google Workspace alias? The alias exists in the Admin console but hasn't been added as a Send mail as address in the user's Gmail settings, so Google's API doesn't recognize it. Add and verify the alias under Gmail Settings, Accounts, Send mail as, then push the signature again. #### Can shared mailboxes like support@ have a signature? Yes. In Microsoft 365, Scribe imports shared mailboxes from Entra ID (the option is on by default) and lets you assign them a signature, which the Outlook add-in and server-side installation apply when someone sends from the mailbox. Shared mailboxes also work in Front. Google Workspace has no shared-mailbox import: add the shared address as an alias, set up as Send mail as, for each person who sends from it. #### Do aliases or shared mailboxes cost extra? Aliases don't: Scribe bills per person whose primary email has a signature assigned, and alias addresses are free. Several signatures on one primary email still count as one user. Scribe's docs don't state whether a shared mailbox with a signature counts as a seat, so confirm before budgeting many of them. #### What if one person is assigned several signatures? Most integrations install one signature per address, so only the highest-priority signature is installed and the others show Not supported. Signature priority sets the order for Outlook users. Front and Zoho Mail can hold more than one signature per address. ### Related Handbook guides - [Microsoft 365 and Exchange Online company-wide signatures](https://www.scribe-mail.com/en-US/handbook/microsoft-365-email-signatures) - [Google Workspace company-wide signatures](https://www.scribe-mail.com/en-US/handbook/google-workspace-email-signatures) - [Client-side vs server-side email signatures](https://www.scribe-mail.com/en-US/handbook/client-side-vs-server-side-email-signatures) - [Sync signatures from Microsoft Entra ID](https://www.scribe-mail.com/en-US/handbook/entra-id-email-signatures) - [Email disclaimers by country and industry](https://www.scribe-mail.com/en-US/handbook/email-disclaimers) ### Email Signatures in the New Outlook, Outlook on the Web and Outlook Mobile: An IT Guide (2026) Source: https://www.scribe-mail.com/en-US/handbook/new-outlook-email-signatures Topic: Rollout Published: 2026-10-24 An IT guide to company email signatures across the new Outlook for Windows, Outlook on the web, classic Outlook, Outlook for Mac and Outlook for iOS and Android: roaming signatures, the end of COM add-ins, event-based web add-ins, Intune settings, troubleshooting and a checklist before the new Outlook becomes the default. > **TL;DR:** The new Outlook for Windows runs on the same web architecture as Outlook on the web, stores signatures in the mailbox (roaming signatures) and does not run COM or VSTO add-ins. That makes web add-ins using the `OnNewMessageCompose` event the one client-side mechanism that covers the new Outlook, Outlook on the web, classic Outlook, the new Outlook for Mac and Outlook for iOS and Android. Microsoft has moved the enterprise opt-out phase, when the new Outlook becomes the default, to March 2027. Before then, IT should retire file- and script-based signatures, confirm an admin-deployed add-in works in every client, and decide how to cover Apple Mail and other non-Outlook apps. *Last reviewed: October 2026.* Most companies still run a mix of Outlook clients: classic Outlook on managed Windows laptops, the new Outlook on a growing number of machines, Outlook on the web on shared and personal computers, and the Outlook apps on phones. Each one used to store and insert signatures differently, which is why signatures drift. This guide explains what the new Outlook changes, which signature methods work in which client, how to manage Outlook on the web and Outlook mobile specifically, and what to check before Microsoft makes the new Outlook the default. Tenant-wide deployment steps are in the [Microsoft 365 rollout guide](https://www.scribe-mail.com/en-US/handbook/microsoft-365-email-signatures). If you only need to change your own signature, see Scribe's posts on [changing your signature in Outlook 365](https://www.scribe-mail.com/en-US/blog/how-to-change-your-signature-in-outlook-365-a-step-by-step-guide) and [adding a signature in Outlook on iPhone](https://www.scribe-mail.com/en-US/blog/how-to-add-a-signature-in-outlook-on-iphone-a-step-by-step-guide). ### What changed with the new Outlook for Windows? Three changes matter for signatures. - **It is built on the web client.** Microsoft describes the new Outlook as "inspired by the Outlook web experience" and running on WebView2, with features delivered from the service rather than through Office update channels ([Microsoft Learn: overview of the new Outlook for Windows](https://learn.microsoft.com/en-us/microsoft-365-apps/outlook/overview-new-outlook-windows)). In practice, a signature that works in Outlook on the web will behave the same way in the new Outlook. - **COM add-ins are gone.** "In new Outlook for Windows, COM add-ins aren't supported." Existing web add-ins "are fully supported, with no extra work required" (same source). Any signature tool that relies on a COM or VSTO add-in, or on a desktop agent writing files into the classic Outlook signature folder, stops working when a user switches. - **Signatures live in the mailbox.** With roaming signatures, Outlook stores signatures in the user's mailbox so they follow the account across devices. Microsoft documents this for Outlook for Windows build 2303 and later, for mailboxes on Microsoft 365 or Outlook.com; Exchange on-premises, third-party and POP/IMAP accounts don't roam ([Microsoft Support: Outlook roaming signatures](https://support.microsoft.com/office/420c2995-1f57-4291-9004-8f6f97c54d15)). #### The timeline IT should plan against Microsoft's rollout has three phases: opt-in (users can toggle to the new Outlook), opt-out (the new Outlook becomes the default but users can switch back) and cutover (no way back). In Message Center post MC949965, last updated February 2026, Microsoft says "the opt-out phase for Enterprise environments will now begin in March 2027 (previously April 2026)", with dates for GCC High and DoD to follow. Existing policies that block or hide the new Outlook keep applying, and admins can stage migration by Entra ID group ([MC949965 mirror](https://mc.merill.net/message/MC949965)). Microsoft has not published a cutover date. Meanwhile its own Learn overview still describes the new Outlook as "a preview for commercial accounts", so expect the wording and dates to move again and check the Message Center rather than relying on this paragraph. ### Which Outlook versions can get a centrally managed signature? There are three ways to put a company signature on Outlook mail: write it into each client's settings, insert it with an admin-deployed add-in when the user starts writing, or add it in transit on the server. The add-in route depends on Outlook's event-based activation: when a user starts a new message, reply or forward, Outlook raises `OnNewMessageCompose` and the add-in calls `setSignatureAsync`. Microsoft lists that event for Outlook on the web, the new and classic Outlook for Windows, the new Outlook for Mac, Android and iOS ([Microsoft Learn: activate add-ins with events](https://learn.microsoft.com/en-us/office/dev/add-ins/develop/event-based-activation)). | Client | Native admin control | Event-based add-in | Server-side (in transit) | | --- | --- | --- | --- | | Outlook on the web | Set-MailboxMessageConfiguration, only if roaming signatures are disabled | Yes | Yes | | New Outlook for Windows | Same as Outlook on the web | Yes | Yes | | Classic Outlook for Windows | None centrally; registry can disable roaming | Yes, on supported builds (Windows 10 1903 or later) | Yes | | New Outlook for Mac | None centrally | Yes (add-in only manifest) | Yes | | Legacy Outlook for Mac | None centrally | No | Yes | | Outlook for iOS and Android | Intune can turn off the "Get Outlook" default signature | Yes, Outlook 4.2352.0 and later (add-in only manifest) | Yes | | Exchange on-premises mailboxes | Transport rules on the server | Depends on the vendor | Depends on mail flow | Two constraints are easy to miss. First, event-based add-ins only launch automatically when an administrator deploys them, not when users install them themselves, unless the vendor has an unrestricted Marketplace listing. Second, add-ins built on the unified manifest for Microsoft 365 aren't supported on Mac or mobile, so vendors need an add-in only (XML) manifest to cover those clients (both from the event-based activation page above). Server-side routing covers every client because the signature is added after the message leaves the mailbox. The trade-off is that users don't see the signature while writing and the Sent Items copy doesn't include it. The [client-side vs server-side guide](https://www.scribe-mail.com/en-US/handbook/client-side-vs-server-side-email-signatures) compares the two in detail. ### How do you manage signatures in Outlook on the web? #### What users see In Outlook on the web, users open **Settings**, then **Account**, then **Signatures**, and pick default signatures for new messages and for replies and forwards. In the new Outlook the path is **Settings > Accounts > Signatures** ([Microsoft Support: add and change a signature in Outlook](https://support.microsoft.com/office/create-add-or-change-an-email-signature-in-outlook-8ee5d4f4-68fd-464a-a1c1-0e1c80bb27f2)). Whatever a user saves here roams to their other roaming-aware clients, which is the opposite of what IT wants from a managed signature. #### What admins can set natively Exchange Online's `Set-MailboxMessageConfiguration` cmdlet has `SignatureHtml`, `AutoAddSignature` and `AutoAddSignatureOnReply` parameters, but they only work when roaming signatures are off. Microsoft added an organization-level switch for that: setting `PostponeRoamingSignaturesUntilLater` to `$true` with `Set-OrganizationConfig` disables roaming signatures in Outlook on the web and the new Outlook, after which "admins can use the signature-related parameters on the Set-MailboxMessageConfiguration cmdlet" ([Microsoft Learn: Set-OrganizationConfig](https://learn.microsoft.com/en-us/powershell/module/exchangepowershell/set-organizationconfig?view=exchange-ps)). Classic Outlook needs the separate `DisableRoamingSignatures` registry value, set per user or through Group Policy under `HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\Office\16.0\Outlook\Setup` (roaming signatures article above). That gets one HTML block per mailbox, pushed by script. It doesn't fill in directory data on its own, doesn't vary by reply or internal recipient, and has to be re-run whenever a title or phone number changes. It's a reasonable stopgap for a small tenant; it isn't a signature program. #### What an add-in changes An admin-deployed signature add-in doesn't depend on the roaming setting, because it inserts the signature into the message being composed rather than editing the stored one. It also re-applies the approved version each time a user starts writing, so a manual edit in settings doesn't survive. Scribe documents exactly that behavior: the approved signature is injected "every time a teammate opens the compose window in Gmail or Outlook", regardless of what's saved in the client ([Scribe: manual edits](https://help.scribe-mail.com/en/what-if-my-teammates-manually-edit-their-email-signature)). #### Troubleshooting Outlook on the web - **Add-in deployed but nothing appears.** Microsoft says admin-deployed add-ins can take up to 72 hours to show up, and Scribe allows up to 72 hours for Microsoft validation ([Scribe: Microsoft 365 add-in](https://help.scribe-mail.com/en/integrations/signatures/microsoft-365-client-side)). Check that the add-in appears under **Integrated apps** in the Microsoft 365 admin center and was assigned to the right users. - **Installation stuck for one user.** For Scribe, the documented fix is to sign out of Scribe and back in, then contact support ([Scribe: Outlook Web add-in signatures not being installed](https://help.scribe-mail.com/en/troubleshooting/outlook-web-add-in-signatures-not-being-installed)). - **Signature missing on some surfaces.** Microsoft notes that in Outlook on the web and the new Outlook, event-based activation "may not work when composing on some non-standard surfaces", such as replying to a meeting invite with RSVP with note or forwarding a meeting from the calendar (event-based activation page above). That's a platform limit, not a misconfiguration. ### How do signatures work in Outlook for iOS and Android? Outlook mobile keeps its own signature setting in the app, and when no custom signature is defined it adds its default "Get Outlook for iOS" or "Get Outlook for Android" line. Admins can turn that default off with an Intune app configuration policy (setting **Default app signature**, key `com.microsoft.outlook.Mail.DefaultSignatureEnabled` set to `false`); users can still add their own signature ([Microsoft Learn: Outlook for iOS and Android configuration with Intune](https://learn.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/outlook-for-ios-and-android/outlook-for-ios-and-android-configuration-with-microsoft-intune)). CodeTwo has reported that this policy blocked all signatures in Outlook for Android at one point, which Microsoft treated as a bug ([CodeTwo KB](https://www.codetwo.com/kb/disable-mobile-outlook-apps-signatures-with-intune/)). We haven't verified the current state, so test it on an Android device before you apply it widely. #### Add-ins on mobile Outlook mobile officially supports the Office.js API up to Mailbox requirement set 1.5, but Microsoft has enabled the pieces a signature add-in needs, including `setSignatureAsync` and `disableClientSignatureAsync`, and supports `OnNewMessageCompose` from Outlook version 4.2352.0 on both iOS and Android ([Microsoft Learn: event-based activation in Outlook mobile add-ins](https://learn.microsoft.com/en-us/office/dev/add-ins/outlook/mobile-event-based)). The same page lists behaviors to expect in testing: - If the user has a signature saved on the device, "it will briefly appear in the message you create, but will be immediately replaced by the signature added by the add-in." - An add-in may run for at most 60 seconds, and only one add-in runs at a time. - The event doesn't fire when a message is created from the **Share** option on iOS. - When replying from the bottom of a message, the signature is added but isn't visible until the compose window is expanded to full screen. For Scribe specifically, the Microsoft 365 add-in lists Web, Desktop, iOS and Android as supported platforms. Some add-in updates can't be applied automatically and must be approved once by an admin in **Integrated apps**, and Scribe names "automatic signature installation for iOS and Android Outlook apps" as one of the reasons to approve them ([Scribe: update the Microsoft add-in](https://help.scribe-mail.com/en/troubleshooting/how-to-update-the-scribe-microsoft-add-in)). If mobile signatures are missing in a tenant where desktop works, check for a pending update first. #### When the add-in isn't enough Users who read company mail in Apple Mail, Gmail or another app on their phone are outside Outlook's reach. Server-side routing is the only way to cover them; see the [mobile signatures guide](https://www.scribe-mail.com/en-US/handbook/mobile-email-signatures) for the app-by-app picture. ### What about classic Outlook and devices without a Microsoft 365 license? Classic Outlook isn't going away overnight. Microsoft's own add-in documentation still covers it, and event-based add-ins run there on Windows 10 version 1903 or later. Scribe lists minimum classic Outlook builds for its add-in: version 16.0.14026.20000 on Current Channel, 16.0.14131.20000 on Monthly Channel and 16.0.14326.10000 on Semi-Annual Channel. On the Mac, the add-in works only in the new Outlook for Mac, version 16.54 (21101001) or later ([Scribe: Outlook add-in not validating](https://help.scribe-mail.com/en/troubleshooting/outlook-add-in-installation-not-validating)). Scribe's own first-line fix when a signature doesn't insert or display correctly is to switch the user to the new Outlook ([Scribe: switch to new Outlook](https://help.scribe-mail.com/en/troubleshooting/switch-to-new-outlook-version)). Machines whose users don't have a Microsoft 365 cloud license, such as Outlook against an on-premises or third-party mailbox, can't use a tenant-deployed add-in. For those, Scribe offers a desktop app. On Windows it can be pushed silently with any RMM tool: deploy a `DomainToken` registry value under `HKLM:\SOFTWARE\Policies\Scribe\Config`, then run the installer with `/S`; an optional `DisableAutoUpdate` value turns off auto-update ([Scribe: Outlook Windows RMM](https://help.scribe-mail.com/en/integrations/signatures/outlook-windows-rmm)). On the Mac, the app ships as a DMG for RMM deployment ([Scribe: Outlook Mac RMM](https://help.scribe-mail.com/en/integrations/signatures/outlook-mac-rmm)). Scribe states these integrations are "only required for users who don't have a Microsoft 365 cloud license." ### How do you troubleshoot signatures across Outlook clients? | Symptom | Likely cause | Fix | | --- | --- | --- | | Old signature reappears after a script set the new one | Roaming signatures overwrote the scripted value | Set `PostponeRoamingSignaturesUntilLater` or move to an add-in | | Signature tool stopped working after a user toggled to the new Outlook | COM/VSTO add-in or file-based agent | Replace with a web add-in or server-side routing | | Add-in signature missing for everyone after deployment | Propagation (up to 72 hours) or add-in not assigned to the users | Check Integrated apps assignment; wait out the window | | Works on desktop, missing on Outlook mobile | Outdated add-in version, unified-manifest-only add-in, old app version | Approve the pending update; confirm Outlook 4.2352.0 or later | | "Get Outlook for iOS" still appended | App default signature | Intune `DefaultSignatureEnabled = false`, tested on Android first | | Missing on calendar replies or meeting forwards | Non-standard compose surface | Expected platform limit; cover with server-side if required | | Classic Outlook on an old build ignores the add-in | Below the minimum build or Windows 10 1903 | Update the channel, or switch the user to the new Outlook | | Signature looks different in classic Outlook | Classic Outlook renders HTML with Word, which ignores some CSS | See the [image and rendering guide](https://www.scribe-mail.com/en-US/handbook/email-signature-image-size) | ### What should IT check before the new Outlook becomes the default? 1. **Inventory how signatures get there today.** Logon scripts writing to `%APPDATA%\Microsoft\Signatures`, COM add-ins, desktop agents and transport rules each fail differently in the new Outlook. Microsoft has a guide to identifying COM add-ins in your tenant ([Microsoft Learn: migrate COM add-ins to web add-ins](https://learn.microsoft.com/en-us/microsoft-365-apps/outlook/get-started/migrate-com-to-web-addins)). 2. **Decide on roaming.** Either leave roaming on and use an add-in or server-side, or turn it off with `PostponeRoamingSignaturesUntilLater` and the classic Outlook registry value if you script signatures. Don't run both a script and roaming. 3. **Deploy the add-in to a pilot group first** and give it the full 72 hours before judging it. 4. **Test every client with the same account:** Outlook on the web, the new Outlook, classic Outlook, Outlook for Mac, Outlook for iOS and Android. Test new message, reply, forward, a shared mailbox and a send-as alias. 5. **Check mobile specifically:** app version, add-in update status, and the Intune default-signature setting. 6. **List who sits outside Outlook:** Apple Mail users, Gmail app users with company accounts, CRM and sequencer tools sending through the mailbox. Decide whether server-side covers them. 7. **Use the migration policy controls.** MC949965 describes admin-controlled, Entra ID group-scoped migration, so you can move departments only after their signature checks pass. 8. **Write the help-desk script** for "my signature disappeared after I switched Outlook", which will be the most common ticket during the opt-out phase. ### Where does Scribe fit across Outlook clients? Scribe's [Microsoft 365 add-in](https://www.scribe-mail.com/en-US/integrations/microsoft-365) is deployed once by a Global Admin from the Microsoft Marketplace to the entire organization and covers Outlook on the web, desktop (classic and new on Windows, new Outlook for Mac), iOS and Android. It shows each teammate's signature status (Pending until they next compose an email, then Installed) so you can see rollout progress per person ([Scribe: installation statuses](https://help.scribe-mail.com/en/signature-installation-statuses-and-errors)). It supports on-reply and internal variants in Outlook on paid plans ([Scribe: signature variants](https://help.scribe-mail.com/en/signature-variants)). For Apple Mail, other mobile apps and tools sending through the mailbox, add [Microsoft 365 server-side routing](https://www.scribe-mail.com/en-US/integrations/microsoft-365-server-side); when both are connected, Scribe uses the add-in where it can and server-side as the fallback ([Scribe: mobile](https://help.scribe-mail.com/en/do-scribe-email-signatures-work-on-mobile)). Unlicensed Windows and Mac machines get the RMM-deployable [desktop app](https://www.scribe-mail.com/en-US/integrations/outlook-windows). Directory data comes from [Microsoft Entra ID](https://www.scribe-mail.com/en-US/integrations/microsoft-entra-id); Scribe doesn't document an on-premises Active Directory connector. You can also check install status across the tenant from an AI assistant through Scribe's [MCP server](https://www.scribe-mail.com/en-US/mcp). ### Frequently asked questions #### Can an admin set one signature for every user in Outlook on the web? Natively, only by script and only with roaming signatures turned off: set PostponeRoamingSignaturesUntilLater to $true with Set-OrganizationConfig, then push HTML with the SignatureHtml and AutoAddSignature parameters of Set-MailboxMessageConfiguration. An admin-deployed signature add-in works without changing the roaming setting and fills in each user's own details. #### Does the new Outlook for Windows support signature add-ins? It supports web add-ins, including the OnNewMessageCompose event that signature add-ins use, but not COM or VSTO add-ins. Tools that wrote signature files for classic Outlook or ran as COM add-ins stop working when a user switches. #### When will the new Outlook become the default for companies? Microsoft's Message Center post MC949965, updated in February 2026, says the opt-out phase for Enterprise environments begins in March 2027, moved from April 2026. Users can still switch back during that phase, and existing policies that block or hide the new Outlook keep applying. No cutover date has been announced. #### Why do Outlook mobile emails end with "Get Outlook for iOS"? Outlook for iOS and Android adds that default line when no custom signature is defined. Admins can turn it off with the Intune app configuration setting Default app signature, key com.microsoft.outlook.Mail.DefaultSignatureEnabled set to false. Test on Android first, because a past bug made the setting block all signatures there. #### Do signature add-ins work in Outlook for iPhone and Android? Yes, if the vendor ships an add-in only manifest and the admin deploys it. Microsoft supports OnNewMessageCompose in Outlook for iOS and Android version 4.2352.0 and later. Scribe's Microsoft 365 add-in lists iOS and Android as supported, and some updates must be approved in Integrated apps to enable mobile installation. #### Do roaming signatures break centrally managed signatures? They break scripted and file-based signatures, because Outlook overwrites them with the version stored in the mailbox. Add-ins and server-side routing don't depend on the roaming setting, since they insert the signature into the message rather than editing the stored one. #### Does Scribe work in Outlook for Mac? Scribe's add-in works in the new Outlook for Mac, version 16.54 (21101001) or later. Users without a Microsoft 365 cloud license can use the Scribe desktop app, which IT can deploy as a DMG through an RMM tool. #### How long until a deployed signature add-in shows up? Microsoft says admin-deployed add-ins can take up to 72 hours to appear, and Scribe allows up to 72 hours for Microsoft validation. In Scribe, each teammate's signature shows Pending until they next compose an email, then Installed. ### Related Handbook guides - [Microsoft 365 company-wide signature rollout](https://www.scribe-mail.com/en-US/handbook/microsoft-365-email-signatures) - [Client-side vs server-side email signatures](https://www.scribe-mail.com/en-US/handbook/client-side-vs-server-side-email-signatures) - [Company email signatures on mobile](https://www.scribe-mail.com/en-US/handbook/mobile-email-signatures) - [Sync signatures with Microsoft Entra ID](https://www.scribe-mail.com/en-US/handbook/entra-id-email-signatures) - [Shared mailbox, alias and reply signatures](https://www.scribe-mail.com/en-US/handbook/shared-mailbox-alias-reply-signatures) - [Email signature rollout playbook](https://www.scribe-mail.com/en-US/handbook/email-signature-rollout-playbook) ### Company Email Signatures on Mobile: iPhone, Android, the Gmail App and Apple Mail (2026 IT Guide) Source: https://www.scribe-mail.com/en-US/handbook/mobile-email-signatures Topic: Rollout Published: 2026-10-24 How to keep company email signatures consistent on phones: how the Gmail, Outlook and Apple Mail apps handle signatures, which apps a signature tool can manage client-side, how server-side routing covers the rest, what Intune and MDM can do, mobile design rules and a test matrix. > **TL;DR:** Every mobile email app keeps its own signature setting, and most of them can't be managed from the outside. Outlook for iOS and Android accept an admin-deployed signature add-in. The Gmail iOS app can carry a centrally set signature if users leave "Mobile Signature" off. Gmail for Android and Apple Mail on iPhone can't be managed client-side, and Apple Mail on iPhone only takes plain text. The only way to put the full company signature on every message sent from every phone is server-side: route outbound mail through a signature service that adds the signature in transit. Most companies combine both: client-side where the app allows it, server-side as the fallback. *Last reviewed: October 2026.* A signature program that looks complete on desktop usually leaks on phones. Sales and field staff send a large share of their email from mobile, often from whichever app came with the phone, and those messages go out with "Sent from my iPhone" or an old title typed in years ago. This guide is for the IT and marketing teams who own the signature: how each mobile app handles signatures, what a signature tool can and can't control in each, how server-side routing closes the gap, what Intune and other device management can do, and how to design and test signatures for small screens. For single-user steps, see Scribe's posts on [adding a signature in Apple Mail on iPhone](https://www.scribe-mail.com/en-US/blog/how-to-add-signature-in-apple-mail-on-iphone-a-step-by-step-guide) and [adding a signature in the Gmail app](https://www.scribe-mail.com/en-US/blog/how-to-add-signature-in-gmail-on-mobile-4-easy-steps). ### Why is mobile where signature consistency breaks? - **Each app stores its own signature.** Gmail's apps, Outlook's apps and Apple Mail all have a per-device or per-account signature field that is separate from the one IT manages on desktop or web. - **Apps default to their own branding.** Outlook mobile appends "Get Outlook for iOS" or "Get Outlook for Android" when no signature is defined ([Microsoft Learn](https://learn.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/outlook-for-ios-and-android/outlook-for-ios-and-android-configuration-with-microsoft-intune)), and Apple Mail's default is "Sent from my iPhone". - **Some apps don't allow injection.** Scribe's documentation is explicit that Gmail for Android and Apple Mail "don't allow external tools to modify the signature in the compose window, which is a technical limitation of those apps" ([Scribe: do signatures work on mobile?](https://help.scribe-mail.com/en/do-scribe-email-signatures-work-on-mobile)). - **Personal phones are unmanaged.** On BYOD devices, IT often can't push app settings at all. Note that the problem is only about *sending* from a phone. A signature added on desktop or web is part of the message, so it displays on the recipient's phone whatever app they use (same Scribe page). ### How does each mobile app handle signatures natively? | App | Where the signature lives | Formatting | Notes for IT | | --- | --- | --- | --- | | Gmail for iPhone and iPad | Settings > Signature settings, per account; "Mobile Signature" toggle | Set in the app | Google: "If you don't create a signature in the Gmail app, new messages use the signature that you set up on your computer." | | Gmail for Android | Per-account mobile signature in the app | Set in the app | Google documents the same fallback to the computer signature; Scribe still lists Android as not covered client-side (see below) | | Outlook for iOS and Android | Signature setting in the app | Set in the app | Default "Get Outlook" line; Intune can disable it; supports event-based add-ins | | Apple Mail on iPhone | Settings > Apps > Mail > Signature, all accounts or per account | "You can only use text in your Mail signatures" | No HTML, logo or banner can be set on the device | | Apple Mail on Mac | Mail > Settings > Signatures | Rich text and images | A desktop app can manage it; see the Apple Mail section | Sources: Google's Gmail signature help for [iPhone and iPad](https://support.google.com/mail/answer/8395?hl=en&co=GENIE.Platform%3DiOS) and [Android](https://support.google.com/mail/answer/8395?hl=en&co=GENIE.Platform%3DAndroid); Apple's [Mail settings on iPhone](https://support.apple.com/guide/iphone/change-mail-settings-iph80dabb18b/ios) and [Mail on Mac](https://support.apple.com/guide/mail/create-and-use-email-signatures-mail11943/mac); Microsoft's Intune configuration page above. ### What can a signature tool manage on each app? This is Scribe's documented coverage. Other vendors face the same app-level limits, so the pattern is similar even if the details differ. | Sending app | Client-side (no mail rerouting) | Server-side (routed through Scribe) | | --- | --- | --- | | Outlook for iOS | Yes, via the Microsoft 365 add-in | Yes | | Outlook for Android | Yes, via the Microsoft 365 add-in | Yes | | Gmail for iOS | Yes, via the Google Workspace app | Yes | | Gmail for Android | No | Yes | | Apple Mail on iPhone | No | Yes | | Apple Mail on Mac | Per-device desktop app (manual or RMM) | Yes | Sources: [Scribe mobile matrix](https://help.scribe-mail.com/en/do-scribe-email-signatures-work-on-mobile), [Microsoft 365 add-in](https://help.scribe-mail.com/en/integrations/signatures/microsoft-365-client-side) (Web, Desktop, iOS, Android), [Google Workspace app](https://help.scribe-mail.com/en/integrations/signatures/google-workspace-client-side) (Web, iOS), and the server-side guides for [Microsoft 365](https://help.scribe-mail.com/en/integrations/signatures/microsoft-365-server-side) and [Google Workspace](https://help.scribe-mail.com/en/integrations/signatures/google-workspace-server-side) (Web, Desktop, Apple Mail, iOS, Android). **A note on Gmail for Android.** Google's help says the Android app falls back to the computer signature when no mobile signature exists, which suggests a signature written into Gmail settings could appear there. Scribe nevertheless supports Gmail for Android only with server-side installation, available on the Business and Enterprise plans, so plan server-side for Android-heavy teams. Scribe's pricing page lists "Gmail Web, Desktop, IOS, Android" under compatibility; that row describes what's possible across both installation methods, and the help center is the authority for which method covers which app. ### What works client-side without rerouting mail? #### Outlook for iOS and Android Microsoft supports the `OnNewMessageCompose` event, which signature add-ins use, in Outlook for iOS and Android from version 4.2352.0, provided the add-in is admin-deployed and uses the add-in only manifest ([Microsoft Learn: event-based activation in Outlook mobile](https://learn.microsoft.com/en-us/office/dev/add-ins/outlook/mobile-event-based)). Behaviors to expect: - A locally saved signature flashes briefly, then the add-in replaces it. - Messages started from the iOS **Share** sheet don't trigger the event, so they go out without the add-in's signature. - Replying from the bottom of a message adds the signature, but it only becomes visible when the compose window is expanded. - Only one event-based add-in runs at a time, for at most 60 seconds. For Scribe tenants, some add-in updates must be approved once in **Microsoft 365 admin center > Settings > Integrated apps**; Scribe lists automatic installation in the iOS and Android Outlook apps as a reason to approve ([Scribe: update the Microsoft add-in](https://help.scribe-mail.com/en/troubleshooting/how-to-update-the-scribe-microsoft-add-in)). The [Outlook guide](https://www.scribe-mail.com/en-US/handbook/new-outlook-email-signatures) covers the full client matrix. #### Gmail for iPhone and iPad With Scribe's Google Workspace app, the signature is written into each user's Gmail settings, and the Gmail iOS app uses it as long as the app's own **Mobile Signature** option is off. Two things surprise users: the signature "gets installed after you send an email", so it isn't visible while composing, and a mobile signature someone set up earlier overrides it ([Scribe: Gmail iOS app signature not showing up](https://help.scribe-mail.com/en/troubleshooting/gmail-ios-app-signature-not-showing-up)). Add "turn off Mobile Signature" to your rollout instructions. #### Apple Mail On a Mac, Scribe's desktop app installs the signature into Apple Mail; each user installs it, or IT pushes the DMG through an RMM tool ([Scribe: Apple Mail](https://help.scribe-mail.com/en/integrations/signatures/apple-mail), [Apple Mail RMM](https://help.scribe-mail.com/en/integrations/signatures/apple-mail-rmm)). There's no documented equivalent for Apple Mail on iPhone, and the app accepts only text signatures, so server-side is the route there. ### How does server-side give full mobile coverage? Server-side installation "changes your mail routing, not your teammates' mailboxes": a rule in Exchange Online or Google Workspace sends outbound mail to the signature service over TLS, the service inserts the right signature and re-signs the message, and it returns to your platform for delivery ([Scribe: Google Workspace server side](https://help.scribe-mail.com/en/integrations/signatures/google-workspace-server-side)). Because the signature is added after the message leaves the device, the app the person used doesn't matter. Things to plan for: - **Users don't see the signature while writing,** and the Sent folder copy doesn't include it. Recipients always get it. - **DKIM changes.** Inserting a signature invalidates the original DKIM signature, so the service re-signs. Scribe publishes a key at `scribe._domainkey` and adds an ARC chain; SPF is unaffected because your platform still delivers the message. Validate DNS before enabling the rule. - **Combine it with client-side.** When both are connected, Scribe defaults to client-side so users see their signature where the app allows it, and server-side covers the rest ([Scribe mobile](https://help.scribe-mail.com/en/do-scribe-email-signatures-work-on-mobile)). The server checks whether the body already carries the signature before inserting one, so messages don't get two. - **Reply and internal variants** still work: Scribe picks the on-reply variant when the subject starts with a reply or forward prefix, and the internal variant when every recipient is on the sender's domain. Setup steps and the security questions your review will ask are in the [Microsoft 365](https://www.scribe-mail.com/en-US/handbook/microsoft-365-email-signatures) and [Google Workspace](https://www.scribe-mail.com/en-US/handbook/google-workspace-email-signatures) guides and the [client-side vs server-side comparison](https://www.scribe-mail.com/en-US/handbook/client-side-vs-server-side-email-signatures). ### What can Intune, Jamf and other device management do? - **Intune and Outlook mobile.** An app configuration policy targeting Outlook can switch off the default "Get Outlook" signature with **Default app signature** (`com.microsoft.outlook.Mail.DefaultSignatureEnabled = false`). Microsoft lists the key for both managed devices and managed apps, so it can reach BYOD phones where only the Outlook app is managed ([Microsoft Learn](https://learn.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/outlook-for-ios-and-android/outlook-for-ios-and-android-configuration-with-microsoft-intune)). It doesn't set a company signature. CodeTwo has reported that this policy once blocked all signatures in Outlook for Android ([CodeTwo KB](https://www.codetwo.com/kb/disable-mobile-outlook-apps-signatures-with-intune/)); test before rolling out. - **Intune and images.** The same policy has a **Block external images** setting whose default (value 1) blocks images hosted on the internet unless the sender is internal or a Safe Sender. Internal recipients still see hosted logos; external recipients' own settings decide what they see. - **Apple devices (Jamf, Intune, other MDM).** We haven't found an Apple-documented MDM setting that pushes a formatted signature to Mail on iPhone, and Apple says Mail signatures on iPhone are text only. Device management can install the Scribe desktop app on Macs; for iPhones, use server-side routing or steer users to Outlook or Gmail. - **Personal phones.** If you can't manage the device, you can still manage the mail flow. Server-side applies to company accounts on any phone. ### How do you make signatures render well on phones? - **Keep it narrow and short.** Most phone screens show roughly 320 to 430 CSS pixels of width. A signature built on a single column, or columns that stack, reads better than a wide two-column card. Scribe states its signatures are responsive by default and generated as inline-styled, table-based HTML ([Scribe: compatibility](https://help.scribe-mail.com/en/are-scribe-email-signatures-compatible-with-all-email-clients)). - **Size images for the display, upload them at twice that.** Set an explicit width and height in pixels, and use a source image about twice as large so it stays sharp on high-density screens. The [image size guide](https://www.scribe-mail.com/en-US/handbook/email-signature-image-size) has dimensions per element. - **Keep file sizes small.** Scribe accepts images up to 5 MB, but recommends keeping GIFs under 2 MB "to avoid slow loading times on mobile devices" and using one animated element per signature ([Scribe: GIFs](https://help.scribe-mail.com/en/can-i-add-a-gif-in-my-email-signature)). - **Make phone numbers and links tappable.** Use `tel:` links for numbers and leave space between icons so a thumb hits the right one. - **Plan for dark mode.** Mobile apps often invert colors. Scribe doesn't offer dark-mode image variants because no reliable cross-client method exists; it advises logos that stay visible on light and dark backgrounds, for example with a solid background ([Scribe: image library](https://help.scribe-mail.com/en/editor/image-library)). Its preview has a dark mode toggle for checking ([Scribe: preview](https://help.scribe-mail.com/en/preview-signatures)). - **Use web-safe fonts.** Phone mail apps fall back to system fonts when they meet a custom font. Scribe limits signatures to 11 web-safe fonts, such as Helvetica, Arial and Georgia, for that reason ([Scribe: fonts](https://help.scribe-mail.com/en/which-fonts-can-i-use-in-my-scribe-email-signature)). - **Use a lighter reply variant.** Most mobile mail is replies. A short on-reply variant without the banner keeps threads readable on a small screen. Scribe applies variants in Outlook and with server-side installation on paid plans, not with the standard Gmail integration ([Scribe: variants](https://help.scribe-mail.com/en/signature-variants)). ### How do you test a mobile rollout? Use one pilot account per platform and send to an external mailbox you can open on both a phone and a computer. For each row, test a new message, a reply and a forward. | Send from | Expected with client-side only | Expected with client-side + server-side | | --- | --- | --- | | Outlook for iOS / Android | Signature from the add-in (check app version and add-in update status) | Add-in signature; server doesn't add a second one | | Gmail for iOS | Signature appears after sending, with Mobile Signature off | Same | | Gmail for Android | Not covered | Signature added in transit | | Apple Mail on iPhone | Not covered; the device's own text signature, if any, is sent | Signature added in transit (ask users to clear "Sent from my iPhone") | | Share sheet on iOS (Outlook) | No add-in signature | Signature added in transit | Check also that the Sent folder copy looks as expected (server-side additions don't appear there), that the logo loads for an external recipient, and that the reply variant is used on replies. ### Where does Scribe fit for mobile? Scribe covers mobile with two methods from one dashboard. Client-side, the [Microsoft 365 add-in](https://www.scribe-mail.com/en-US/integrations/microsoft-365) reaches Outlook for iOS and Android and the [Google Workspace app](https://www.scribe-mail.com/en-US/integrations/google-workspace-gmail) reaches the Gmail iOS app, with no change to mail flow. Server-side routing for [Microsoft 365](https://www.scribe-mail.com/en-US/integrations/microsoft-365-server-side) or [Google Workspace](https://www.scribe-mail.com/en-US/integrations/google-workspace-server-side), on the Business and Enterprise plans, covers Gmail for Android, Apple Mail and every other app, and Scribe falls back to it automatically where client-side can't reach. Per-teammate installation statuses show who is covered ([Scribe: statuses](https://help.scribe-mail.com/en/signature-installation-statuses-and-errors)), and the same data is available through the [API](https://www.scribe-mail.com/en-US/api) and the [MCP server](https://www.scribe-mail.com/en-US/mcp) if you want to audit coverage from a script or an AI assistant. Pricing is per user, with a free plan for up to two users and a 14-day trial ([pricing](https://www.scribe-mail.com/en-US/pricing)). ### Frequently asked questions #### Can IT set the email signature on employees' phones centrally? Partly. An admin-deployed add-in can insert the signature in Outlook for iOS and Android, and a signature written into Gmail settings is used by the Gmail iPhone app when Mobile Signature is off. Gmail for Android and Apple Mail on iPhone can't be managed this way, so full coverage needs server-side routing, which adds the signature in transit. #### How does the Gmail mobile signature work? The Gmail app has its own mobile signature per account. Google says that if you don't create one in the app, new messages use the signature set on the computer. With a centrally managed Gmail signature, users should leave the app's Mobile Signature option off so it doesn't override the company version. #### Why doesn't my company signature show in Apple Mail on iPhone? Apple Mail on iPhone keeps its own signature, and Apple says you can only use text in it, so no tool can install a formatted signature in the app. Signatures can be added to mail sent from Apple Mail on iPhone only server-side, after the message is sent. #### Do email signatures work on Android? In Outlook for Android, yes, through an admin-deployed add-in on Outlook 4.2352.0 or later. In Gmail for Android, Scribe supports signatures only with server-side installation, on the Business and Enterprise plans. #### How do I remove "Get Outlook for iOS" from company emails? Create an Intune app configuration policy for Outlook and set Default app signature to Off, which is the key com.microsoft.outlook.Mail.DefaultSignatureEnabled set to false. Test on Android first: CodeTwo has reported that the setting once blocked all signatures in Outlook for Android. #### Will server-side signatures appear in the sender's Sent folder on their phone? No. The signature is added after the message leaves the mailbox, so the Sent copy is the pre-processing version. Recipients always receive the signature. #### What size should a mobile email signature be? Design for a narrow screen: a single column or stacking columns, images with explicit pixel dimensions uploaded at about twice their display size, small files (Scribe recommends GIFs under 2 MB), tappable tel: links and a short reply variant for threads. #### Can Intune or Jamf push an email signature to iPhones? Intune can turn off Outlook mobile's default signature but doesn't set a company signature, and we haven't found an Apple-documented MDM setting that pushes a formatted signature to Mail on iPhone. Use server-side routing for iPhones, or move users to Outlook or Gmail apps that can be managed client-side. ### Related Handbook guides - [Client-side vs server-side email signatures](https://www.scribe-mail.com/en-US/handbook/client-side-vs-server-side-email-signatures) - [Signatures in the new Outlook, Outlook on the web and Outlook mobile](https://www.scribe-mail.com/en-US/handbook/new-outlook-email-signatures) - [Google Workspace company-wide signatures](https://www.scribe-mail.com/en-US/handbook/google-workspace-email-signatures) - [Email signature size, images and hosting](https://www.scribe-mail.com/en-US/handbook/email-signature-image-size) - [Email disclaimers by country and industry](https://www.scribe-mail.com/en-US/handbook/email-disclaimers) ### Office 365 and Microsoft 365 Email Signatures: The Company-Wide Rollout Playbook for IT (2026) Source: https://www.scribe-mail.com/en-US/handbook/microsoft-365-email-signatures Topic: Rollout Published: 2026-10-24 The IT playbook for company-wide Microsoft 365 email signatures: choosing between mail flow rules, an Outlook add-in and server-side routing, roaming signatures and the new Outlook, Entra ID data, a phased rollout plan and troubleshooting. > **TL;DR:** Microsoft 365 has no built-in central signature manager. You can append one HTML block per rule with an Exchange Online mail flow rule, deploy a signature add-in to every mailbox through Integrated Apps, or route outbound mail through a signature relay with connectors. Most IT teams with 100+ mailboxes deploy an add-in for in-compose signatures, add server-side routing for devices the add-in can't reach, feed both from Microsoft Entra ID, and roll out to a pilot group first. *Last reviewed: October 2026. Covers Exchange Online, the new Outlook for Windows, classic Outlook for Windows, Outlook for Mac, Outlook on the web, and Outlook for iOS and Android.* This is the IT rollout playbook for company-wide email signatures in Microsoft 365 (still widely called Office 365). It is written for the admin who has to choose an architecture, get it through a security review, deploy it to hundreds or thousands of mailboxes, and keep it working when Microsoft changes Outlook. If you want a shorter overview of the three management options with screenshots of user settings, read our [Office 365 email signature management guide](https://www.scribe-mail.com/en-US/blog/master-email-signature-management-in-office-365-a-step-by-step-guide) first. End users who only need to edit their own signature can follow [how to change your signature in Outlook 365](https://www.scribe-mail.com/en-US/blog/how-to-change-your-signature-in-outlook-365-a-step-by-step-guide). ### What are your options for company-wide signatures in Microsoft 365? There are five mechanisms. Only the last two are built for central control at scale, and they solve different problems. 1. **User-managed signatures.** Each person writes a signature in Outlook. In current Outlook builds these are "roaming" signatures stored in the mailbox rather than on the device (see the next section). Free, but nothing is enforced. 2. **PowerShell per mailbox.** `Set-MailboxMessageConfiguration` with `SignatureHtml`, `AutoAddSignature` and `AutoAddSignatureOnReply` can write a signature into each mailbox, but Microsoft documents that this only works for Outlook on the web and the new Outlook when roaming signatures are disabled for the tenant ([Set-OrganizationConfig, Microsoft Learn](https://learn.microsoft.com/en-us/powershell/module/exchangepowershell/set-organizationconfig?view=exchange-ps)). You also have to build and schedule the script yourself. 3. **Exchange Online mail flow rule (transport rule).** The "Apply disclaimers" rule appends or prepends HTML to messages in transit, with tokens such as `%%DisplayName%%` filled from the directory ([Microsoft Learn](https://learn.microsoft.com/en-us/exchange/security-and-compliance/mail-flow-rules/disclaimers-signatures-footers-or-headers)). 4. **A signature add-in deployed by the admin.** A web add-in that Outlook activates when a message is composed and that inserts the signature in the compose window, on desktop, web and mobile. 5. **A server-side signature relay.** Exchange Online routes outbound mail through a third-party smart host that inserts the signature and hands the message back, so every client and device is covered. | Method | Seen while composing | Covers mobile and Apple Mail | Per-user data | Design control | Effort to run | | --- | --- | --- | --- | --- | --- | | User-managed (roaming) | Yes | Outlook apps only | Typed by hand | None | High (chasing people) | | PowerShell per mailbox | Yes (web and new Outlook) | No | Your script | Raw HTML | High (custom code) | | Mail flow rule | No | Yes | Directory tokens | Raw HTML, one block per rule | Medium | | Admin-deployed add-in | Yes | Outlook for iOS and Android; not Apple Mail | Directory and HR data | Visual editor (vendor) | Low | | Server-side relay | No | Yes, any client | Directory and HR data | Visual editor (vendor) | Low after setup | The practical pattern for most companies is the add-in plus server-side relay, with the add-in as the default and the relay as a fallback. The [client-side vs server-side guide](https://www.scribe-mail.com/en-US/handbook/client-side-vs-server-side-email-signatures) covers that trade-off in depth. ### How do roaming signatures and the new Outlook change things? Two Microsoft changes decide which signature tools still work in 2026. #### Roaming signatures Microsoft moved Outlook signatures from the local computer into the mailbox. Microsoft's support article says roaming signatures are available from Outlook build 2303, that signatures are stored in the user's mailbox and follow the account across devices, and that mailboxes on Exchange Server on-premises, third-party services and POP/IMAP accounts are excluded ([Outlook roaming signatures, Microsoft Support](https://support.microsoft.com/office/420c2995-1f57-4291-9004-8f6f97c54d15)). The consequence for IT: old scripts that dropped `.htm` files into `%APPDATA%\Microsoft\Signatures` or set mailbox signatures with PowerShell stop behaving predictably. Microsoft's switch for this is the tenant-level `PostponeRoamingSignaturesUntilLater` parameter. Per Microsoft Learn, setting it to `$true` disables roaming signatures in Outlook on the web and the new Outlook for Windows, after which the `Set-MailboxMessageConfiguration` signature parameters work again; for classic Windows clients the registry setting still applies ([Microsoft Learn](https://learn.microsoft.com/en-us/powershell/module/exchangepowershell/set-organizationconfig?view=exchange-ps)). ``` Connect-ExchangeOnline Set-OrganizationConfig -PostponeRoamingSignaturesUntilLater $true ``` You only need this if you plan to push signatures with PowerShell. Add-ins and server-side relays don't depend on it. #### The new Outlook for Windows The new Outlook for Windows does not run COM or VSTO add-ins; Microsoft points customers to web add-ins instead ([Overview of the new Outlook for Windows, Microsoft Learn](https://learn.microsoft.com/en-us/microsoft-365-apps/outlook/overview-new-outlook-windows); [Migrate COM add-ins to web add-ins](https://learn.microsoft.com/en-us/microsoft-365-apps/outlook/get-started/migrate-com-to-web-addins)). Any signature tool that relies on a COM add-in or a desktop agent writing files will not work there. Web add-ins insert signatures with **event-based activation**. The `OnNewMessageCompose` event fires when a user starts a new message, reply or forward, and Microsoft lists it as supported in Outlook on the web, the new and classic Outlook for Windows, the new Outlook for Mac, and Outlook for Android and iOS. Two constraints matter for admins: event-based add-ins only launch automatically when an administrator deployed them (or they have an unrestricted Marketplace listing), and when an admin-deployed add-in changes its manifest, users can be blocked until the admin consents to the update ([Activate add-ins with events, Microsoft Learn](https://learn.microsoft.com/en-us/office/dev/add-ins/develop/event-based-activation)). ### Why do native mail flow rule signatures fall short at scale? A mail flow rule is the only free, central option, and for a plain legal footer it is often enough. For a full branded signature, the limits show up quickly: - **No compose view.** The rule runs in transit. The sender never sees the signature while writing, and the copy in Sent Items is the version from before the rule ran. - **One HTML block per rule.** Different teams, brands or languages mean one rule each, with conditions you maintain by hand. - **Directory tokens only.** Microsoft supports 23 tokens, from `%%City%%` and `%%Department%%` to `%%Title%%` and `%%MobilePhone%%` ([Microsoft Learn](https://learn.microsoft.com/en-us/exchange/security-and-compliance/mail-flow-rules/disclaimers-signatures-footers-or-headers)). There is no logic per field, so if a template says "Mobile: %%MobilePhone%%" and the attribute is empty, the label still appears. HR data, booking links and custom attributes are out of reach. - **Stacking in threads.** Microsoft recommends an exception that looks for unique text from the disclaimer so it is only added to the original message. Without it, every reply in a long thread adds another copy. - **Fallback behavior.** If the rule can't modify a message (for example, it is encrypted), it falls back to Wrap (default: the original becomes an attachment of a new message), Ignore or Reject. Microsoft warns not to use Wrap on rules that affect incoming external mail because it interferes with Safe Attachments scanning ([Microsoft Learn](https://learn.microsoft.com/en-us/exchange/security-and-compliance/mail-flow-rules/disclaimers-signatures-footers-or-headers)). - **No reporting.** You can't see who has which signature or measure clicks. If you keep a rule for a disclaimer, set it to **Test without Policy Tips** first, scope it to recipients outside the organization, and choose **Ignore** as the fallback unless a missing disclaimer must block delivery. Templates for the disclaimer text itself are in the [email disclaimers guide](https://www.scribe-mail.com/en-US/handbook/email-disclaimers). ### What do you need before you start? Most failed rollouts stall on permissions or dirty directory data, not on the signature tool. Check these first. | Item | Why it matters | Who | | --- | --- | --- | | Global Administrator account | Scribe's add-in and the Entra ID connection both require a Global Admin to consent ([Scribe docs](https://help.scribe-mail.com/en/integrations/signatures/microsoft-365-client-side), [Entra ID docs](https://help.scribe-mail.com/en/teammates/connect-microsoft-entra-id)) | IT | | Exchange admin access | Needed for connectors and the mail flow rule if you add server-side coverage | IT | | Conditional access and app consent policies | Policies that block third-party app consent will stop the Entra ID authorization | IT / security | | DNS access for each sending domain | Server-side routing requires a DKIM record for the relay | IT | | Entra ID data audit | Job title, department, phone and office fields become what customers see | IT + HR | | Outlook versions | Scribe lists minimum classic Outlook builds: 16.0.14026.20000 (Current Channel), 16.0.14131.20000 (Monthly Enterprise), 16.0.14326.10000 (Semi-Annual); on Mac, the new Outlook 16.54 or later ([Scribe docs](https://help.scribe-mail.com/en/troubleshooting/outlook-add-in-installation-not-validating)) | IT | | Pilot group | A security group or Entra administrative unit of 10 to 30 people across departments and devices | IT + Marketing | | Template sign-off | Brand, legal text and per-team variants approved before deployment | Marketing + Legal | A quick way to find empty fields in Entra ID before they reach a signature, using Microsoft Graph PowerShell: ``` Connect-MgGraph -Scopes "User.Read.All" Get-MgUser -All -Property displayName,mail,jobTitle,department,mobilePhone,businessPhones,accountEnabled | Where-Object { $_.accountEnabled -and (-not $_.jobTitle -or -not $_.department) } | Select-Object displayName,mail,jobTitle,department ``` ### How do you deploy a signature add-in to every Outlook user? Microsoft's centralized deployment lives in the Microsoft 365 admin center under **Settings > Integrated apps**. You can assign an add-in to everyone, to specific users or groups, or just to yourself, and Microsoft recommends assigning by group so membership changes flow through automatically. Microsoft also notes that add-ins can take 24 to 72 hours to appear ([Deploy Office Add-ins in the Microsoft 365 admin center, Microsoft Learn](https://learn.microsoft.com/en-us/microsoft-365/admin/manage/manage-deployment-of-add-ins)). With Scribe, the add-in is listed on Microsoft Marketplace and the flow is ([Scribe: Microsoft 365](https://help.scribe-mail.com/en/integrations/signatures/microsoft-365-client-side)): 1. In Scribe, open the Microsoft 365 integration and click **Install Scribe Add-in**. This opens the Microsoft Marketplace listing. 2. Click **Get it now** and sign in with the Global Admin account. If you land in your Outlook inbox instead of the admin center, the account is not a Global Admin. 3. Choose who gets the add-in. Select **Entire organization**, or a smaller group if you want to pilot first. 4. Accept the permission request and click **Next**, then **Finish deployment**. 5. Back in Scribe, confirm with **Yes I installed it**. 6. Wait for Microsoft validation. Scribe's docs say this can take up to 72 hours and that you are notified by email when it's done. 7. Open your signatures list and install signatures for everyone at once, or one signature at a time for a progressive rollout ([Install signatures](https://help.scribe-mail.com/en/install-signatures)). What users see: nothing to install. Scribe states that teammates don't need to take any action, and that the signature appears in the compose window on Outlook web, desktop, iOS and Android ([Scribe docs](https://help.scribe-mail.com/en/integrations/signatures/microsoft-365-client-side)). In the Scribe dashboard a Microsoft 365 signature shows **Pending** until the person next composes an email, because that is when Outlook installs it ([Installation statuses](https://help.scribe-mail.com/en/signature-installation-statuses-and-errors)). Two behaviors worth knowing before you announce the rollout: - **Manual edits don't stick.** Scribe re-inserts the approved signature each time the compose window opens, so a teammate who edits their local signature only changes that one email ([Scribe docs](https://help.scribe-mail.com/en/what-if-my-teammates-manually-edit-their-email-signature)). - **Replies and internal mail can use lighter variants.** On-reply and internal variants work in Outlook on paid plans ([Signature variants](https://help.scribe-mail.com/en/signature-variants)). Signature priority decides which signature is the default when someone has more than one ([Signature priority](https://help.scribe-mail.com/en/signature-priority)). ### How do you add server-side coverage with connectors and a mail flow rule? The add-in covers every Outlook client. It does not cover Apple Mail, other third-party mail apps, or tools that send through the mailbox without opening an Outlook compose window. For those, add server-side routing. With Scribe it takes four parts: an outbound connector, an inbound connector, a mail flow rule and DKIM ([Scribe: Microsoft 365 server side](https://help.scribe-mail.com/en/integrations/signatures/microsoft-365-server-side)). 1. **Outbound connector.** In the Exchange admin center, go to **Mail flow > Connectors > Add a connector**. From **Office 365** to **Partner organization**. Name it `Scribe signature outbound`. 2. **Use of connector.** Choose **Only when I have a transport rule set up that redirects messages to this connector**. 3. **Routing.** Choose **Route email through these smart hosts** and add `smtp.server.scribe-mail.com`. 4. **Security.** Choose **Always use Transport Layer Security (TLS)**, **Issued by a trusted certificate authority (CA)**, and require the subject name or SAN to match `smtp.server.scribe-mail.com`. 5. **Validate.** Use `scribe-o365-test@scribe-mail.com` as the test address. Scribe notes that Microsoft's probe doesn't always complete even when routing is correct, and that you can save and continue. 6. **Inbound connector.** Add a connector from **Your organization's email server**, named `Scribe signature inbound`, that authenticates by sender IP: `15.236.243.144` and `51.44.50.107`. 7. **Mail flow rule.** Under **Mail flow > Rules**, create `Route outbound mail via Scribe Signature`: apply if the sender is located **InOrganization**; redirect the message to the `Scribe signature outbound` connector; except if the message header `X-Scribe-Processed` matches `Processed`. Save and enable it. 8. **DKIM.** In Scribe, click **Configure DKIM** and publish the `scribe._domainkey` record for each sending domain. Scribe treats this as required: inserting a signature changes the body, which breaks the original DKIM signature, so Scribe re-signs the message and adds an ARC chain (RFC 8617). 9. **Install signatures** from the Scribe signatures list, then send a real test email to an external mailbox and check for the `X-Scribe-Processed` header. | Network item | Value | | --- | --- | | Outbound smart host | `smtp.server.scribe-mail.com` (TLS, CA-issued certificate, SAN match) | | Inbound source IPs | `15.236.243.144`, `51.44.50.107` | | Loop prevention | Rule exception on `X-Scribe-Processed`, plus a body check for an existing signature | | Rollback | Disable the mail flow rule; connectors can stay in place unused | When both the add-in and server-side routing are connected, Scribe defaults to the add-in so people see their signature while composing, and server-side keeps covering clients the add-in can't reach ([Integrations overview](https://help.scribe-mail.com/en/integrations-overview)). A note on sales tools: mail that a CRM or sequencer sends through the user's Exchange Online mailbox passes the rule and gets the signature. Scribe's docs give HubSpot one-to-one and sequence emails as an example, and note that mail a tool sends from its own servers, such as HubSpot marketing email, never reaches the rule and gets no signature ([Scribe docs](https://help.scribe-mail.com/en/integrations/signatures/hubspot-server-side)). ### How do you feed signatures with Microsoft Entra ID data? The signature is only as good as the directory behind it. Connect Entra ID once and let it drive both content and assignment. 1. In Scribe, go to **Settings > Integrations** and click **Connect** on Microsoft Entra ID. 2. Sign in with a Global Admin and accept the permissions. Scribe describes the access as read-only ([Connect Microsoft Entra ID](https://help.scribe-mail.com/en/teammates/connect-microsoft-entra-id)). 3. Select who to sync, by person, by administrative unit, or by group. Groups can be filtered by type: Microsoft 365 groups, mail-enabled security groups, security groups and distribution groups. 4. Keep **Import email aliases** and **Import shared mailboxes** on (both are on by default) if aliases and shared mailboxes need signatures. 5. Set auto-sync per unit or group so new hires appear without manual work. The Microsoft Graph permissions Scribe requests, from its [scopes page](https://help.scribe-mail.com/en/security/scopes-used-from-microsoft-entra-id): | Permission | Type | Used for | | --- | --- | --- | | `User.Read.All` | Application | Sync user profiles | | `Group.Read.All`, `GroupMember.Read.All` | Application | Groups and memberships | | `AdministrativeUnit.Read.All` | Application | Create departments from administrative units | | `Domain.Read.All` | Application | Import your domains | | `openid`, `profile`, `email`, `User.Read`, `offline_access` | Delegated | Sign-in and keeping the connection alive | The fields Scribe stores include profile picture, first and last name, job position, mobile, work phone, fax, department, office, street address, city, state, postal code, country, group and administrative-unit memberships, and domains. Fields sync once a day in your time zone, and an admin can force a refresh ([Smart Fields](https://help.scribe-mail.com/en/smart-fields)). If a value is empty, Scribe drops that block and closes the layout around it, which fixes the "empty label" problem of transport-rule tokens. For assignment, the scalable setup is a rule rather than a list: assign a signature by Smart Field condition (for example "Department is Sales") and tick "auto-assign this signature to all future teammates" ([Assign teammates](https://help.scribe-mail.com/en/assign-teammates-to-a-signature)). When HR is the better source for titles or phone numbers, Scribe can pull fields from HRIS tools such as Workday, BambooHR, Rippling, HiBob or UKG ([Integrations overview](https://help.scribe-mail.com/en/integrations-overview)). Scribe syncs from Entra ID; it does not document a connector for on-premises Active Directory. ### What does a phased rollout look like for 100 to 5,000 mailboxes? Microsoft's own recommendation for add-ins is staged: a small set of stakeholders and IT first, then a wider group, then everyone ([Microsoft Learn](https://learn.microsoft.com/en-us/microsoft-365/admin/manage/manage-deployment-of-add-ins)). A schedule that works for most tenants: | Phase | Scope | What to do | Exit criteria | | --- | --- | --- | --- | | 0. Prepare (week 0) | None | Audit Entra ID fields, approve templates and variants, decide on server-side, publish DKIM | Missing-field list under 5% of users | | 1. Pilot (week 1) | 10-30 users across departments, OS and phones | Deploy add-in to a pilot group; enable the server-side rule scoped to pilot senders if you test it | Test matrix below passes; no deliverability changes | | 2. Early departments (week 2) | One or two teams that email customers most (often Sales and Support) | Assign by department condition, notify teammates from the install modal | Installed status above 95% for the group | | 3. Company-wide (week 3) | Entire organization | Switch the add-in to everyone; enable auto-assign for future hires | Help-desk tickets back to baseline | | 4. Steady state | Everyone | Marketing owns templates and banners; IT owns integrations and the rule | Quarterly data audit scheduled | Scribe's install modal has a **Notify teammates via email about their new signature** option that sends each person a preview and tells them no action is needed ([Install signatures](https://help.scribe-mail.com/en/install-signatures)), which saves writing the announcement yourself. For a single-tenant setup Scribe estimates the technical part at around 10 minutes for IT and 15 to 20 minutes for Marketing; the calendar time comes from Microsoft's add-in propagation and internal sign-off ([Scribe docs](https://help.scribe-mail.com/en/how-long-does-it-take-to-set-up-scribe)). ### How do you verify the rollout? Don't trust "deployed" in an admin center. Check from the recipient side, on each client. | Test | Expected result | | --- | --- | | New message in Outlook on the web | Signature in compose window | | New message in new Outlook for Windows and in classic Outlook | Signature in compose window (classic needs a supported build) | | New message in Outlook for Mac (new Outlook) | Signature in compose window | | Outlook for iOS and Android | Signature inserted by the add-in | | Apple Mail or a phone's native mail app | Signature only if server-side routing is on | | Reply, and email to a colleague | On-reply and internal variants if published | | Send from an alias and from a shared mailbox | The signature assigned to that address | | External recipient, view headers | `X-Scribe-Processed: Processed` on server-side mail; DKIM and DMARC pass | In Scribe, each teammate shows Installed, Pending, Not activated, Not installed, Failed, Not supported or Access lost, and you can filter the signature's teammate list by installation status and by missing information ([Statuses and errors](https://help.scribe-mail.com/en/signature-installation-statuses-and-errors), [Assign teammates](https://help.scribe-mail.com/en/assign-teammates-to-a-signature)). ### How do you troubleshoot common Microsoft 365 signature problems? | Symptom | Likely cause | Fix | | --- | --- | --- | | Add-in still not validated after 72 hours | Wrong account or domain chosen; not deployed to the entire organization; installed in one Outlook account instead of as an integrated app | Check the account, the "Entire organization" choice and **Settings > Integrated apps** ([Scribe docs](https://help.scribe-mail.com/en/troubleshooting/outlook-add-in-installation-not-validating)) | | Signature missing in classic Outlook or Outlook for Mac | Build below the supported minimum, or legacy Outlook for Mac | Update the channel build, or switch to the new Outlook ([Scribe docs](https://help.scribe-mail.com/en/troubleshooting/switch-to-new-outlook-version)) | | Integrated Apps shows "Upgrade" for the add-in | An update that needs admin consent | Open the add-in in Integrated apps and approve it with **Know more and update**; mobile signatures depend on keeping it current ([Scribe docs](https://help.scribe-mail.com/en/troubleshooting/how-to-update-the-scribe-microsoft-add-in)) | | Outlook on the web install stuck | Stale session | Sign out of Scribe and back in; contact support if it persists ([Scribe docs](https://help.scribe-mail.com/en/troubleshooting/outlook-web-add-in-signatures-not-being-installed)) | | Status "Failed: user not found" | The email doesn't match a mailbox in the tenant | Correct the address or the sync selection | | Signature appears twice | A user default signature or a leftover transport-rule footer plus the managed signature | Remove old rules and personal defaults; keep one source | | Connector validation fails | Microsoft's probe didn't complete | Save, enable the rule, and test with a real email | | DKIM fails at the recipient after enabling server-side | DKIM record not published or not validated for that domain | Publish `scribe._domainkey` per domain before enabling the rule | | Disclaimer repeats in long threads | Mail flow rule without an exception | Add the "subject or body matches" exception Microsoft recommends | ### What will your security review ask? - **Does mail leave Microsoft?** Not with the add-in: Scribe states that with the cloud add-in emails don't go through Scribe servers. With server-side routing, outbound mail from senders inside the organization makes one TLS hop to Scribe and back. - **What does the relay change?** Scribe's documentation says it inserts the signature and adds its own headers (`X-Scribe-Processed`, a routing header, a fresh `DKIM-Signature`, an ARC chain and the matching `Content-Type`), and passes recipients, subject, attachments and body text through unchanged. - **SPF and DMARC?** SPF is unaffected because Exchange Online still makes the final delivery; DKIM is re-signed by Scribe once the record is validated. - **Directory access?** Read-only Graph application permissions listed above; nothing is written back to Entra ID. - **Certifications?** Scribe states it is SOC 2 Type II and GDPR compliant, publishes a [Trust Center](https://security.scribe-mail.com), and shares its report under NDA ([Scribe security](https://help.scribe-mail.com/en/what-scribe-does-concerning-security)). Sign-in supports SSO (SAML) and 2FA. - **Exit plan?** Disable the mail flow rule and remove the add-in from Integrated Apps. More detail for the review is on Scribe's [security page](https://www.scribe-mail.com/en-US/solutions/security). ### What about Exchange on-premises, hybrid and edge cases? - **Exchange Server on-premises mailboxes** don't get roaming signatures and aren't covered by Exchange Online mail flow rules. For Windows users without a Microsoft 365 cloud license, Scribe documents a desktop app deployed through your RMM tool with a `DomainToken` registry key at `HKLM:\SOFTWARE\Policies\Scribe\Config` and a silent installer (`/S`) ([Scribe docs](https://help.scribe-mail.com/en/integrations/signatures/outlook-windows-rmm)). Ask Scribe for a hybrid design review before committing. - **Shared mailboxes** can be imported from Entra ID and assigned their own signature; shared mailbox signatures are on every Scribe plan ([pricing](https://www.scribe-mail.com/en-US/pricing)). - **Aliases** can each have their own signature at no extra cost, because Scribe bills per primary address ([Scribe docs](https://help.scribe-mail.com/en/how-do-scribe-email-signatures-work-with-email-aliases)). - **Government clouds** (GCC, GCC High, DoD) have different add-in and connector availability. Confirm support with your vendor before planning a rollout there. ### Where does Scribe fit in a Microsoft 365 tenant? Scribe gives Microsoft 365 tenants the two deployment paths above from one dashboard: the [Microsoft 365 add-in](https://www.scribe-mail.com/en-US/integrations/microsoft-365) and [server-side routing](https://www.scribe-mail.com/en-US/integrations/microsoft-365-server-side), both fed by [Microsoft Entra ID sync](https://www.scribe-mail.com/en-US/integrations/microsoft-entra-id). Two things are specific to Scribe. First, the whole workspace can be run from an AI assistant: the hosted MCP server is listed in the Claude directory and ChatGPT, with read actions auto-approved and write actions confirmed, so "which signatures are published, who are they assigned to, and are any integrations failing?" is a one-line audit ([Scribe MCP](https://www.scribe-mail.com/en-US/mcp)). Second, signatures, installs and teammates are exposed through a REST [API](https://www.scribe-mail.com/en-US/api), including per-email installation state, so you can wire signature checks into onboarding. Pricing is per user with a free plan for two users and a 14-day trial ([pricing](https://www.scribe-mail.com/en-US/pricing)). ### Frequently asked questions #### Can I set one email signature for all users in Office 365? Natively, only in transit: an Exchange Online mail flow rule with the Apply disclaimers action appends one HTML block, personalized with directory tokens such as %%DisplayName%% and %%Title%%, to matching messages. Users don't see it while composing. For a signature that appears in Outlook's compose window for everyone, deploy a signature add-in to the whole organization from Integrated Apps. #### Do roaming signatures break centrally managed signatures? They break file-based and PowerShell-based approaches, because Outlook now stores signatures in the mailbox. Microsoft's PostponeRoamingSignaturesUntilLater setting disables roaming signatures in Outlook on the web and the new Outlook so Set-MailboxMessageConfiguration works again. Admin-deployed add-ins and server-side relays don't depend on that setting. #### Do signature tools work in the new Outlook for Windows? Only if they use web add-ins or server-side routing. The new Outlook doesn't run COM or VSTO add-ins. Microsoft supports the OnNewMessageCompose event that signature add-ins use in the new and classic Outlook for Windows, Outlook on the web, the new Outlook for Mac, and Outlook for iOS and Android. #### How long does it take to deploy a signature add-in in Microsoft 365? Microsoft says admin-deployed add-ins can take 24 to 72 hours to appear for users, and Scribe's documentation also allows up to 72 hours for Microsoft validation. The admin steps themselves take minutes. In Scribe, a Microsoft 365 signature shows Pending until the person next composes an email. #### Do I need Global Admin rights? For Scribe, yes: a Microsoft 365 Global Administrator must deploy the add-in and authorize the Entra ID connection. Server-side routing also needs Exchange admin permissions to create connectors and the mail flow rule. #### Will signatures work in Outlook for iPhone and Android? With Scribe's add-in, yes: it supports Outlook on the web, desktop, iOS and Android, and Scribe notes some add-in updates must be approved in Integrated Apps to enable mobile installation. Apple Mail and other non-Outlook apps need server-side routing. #### Does server-side routing affect deliverability? It changes the message body, which breaks the original DKIM signature, so the relay must re-sign. Scribe adds a new DKIM signature with a key published at scribe._domainkey and an ARC chain, and SPF is unaffected because Exchange Online still delivers the message. Publish and validate the DKIM record before enabling the rule. #### Does Scribe sync from on-premises Active Directory? Scribe documents directory sync with Microsoft Entra ID. It doesn't document an on-premises Active Directory connector. For Windows users without a Microsoft 365 cloud license, Scribe offers a desktop app deployed through RMM tools. ### Related Handbook guides - [Client-side vs server-side email signatures](https://www.scribe-mail.com/en-US/handbook/client-side-vs-server-side-email-signatures) - [Google Workspace company-wide signatures](https://www.scribe-mail.com/en-US/handbook/google-workspace-email-signatures) - [Email disclaimers by country and industry](https://www.scribe-mail.com/en-US/handbook/email-disclaimers) - [Company email signature policy and templates](https://www.scribe-mail.com/en-US/blog/best-practices-for-company-wide-email-signature-management) ### How to Manage and Audit Company Email Signatures from Claude, ChatGPT and Copilot (MCP Guide, 2026) Source: https://www.scribe-mail.com/en-US/handbook/manage-email-signatures-with-ai-mcp Topic: AI & automation Published: 2026-10-24 The hands-on IT guide to managing email signatures from an AI assistant: connecting Claude, ChatGPT, Microsoft Copilot, Gemini, Cursor and the Scribe CLI, what the OAuth connection can do, copy-paste audit prompts mapped to real MCP tools, a draft-to-publish change workflow and governance rules. > **TL;DR:** You can audit and manage company email signatures from Claude, ChatGPT, Microsoft Copilot, Gemini or Cursor by connecting them to an email signature MCP server. With Scribe, Claude and ChatGPT connect in one click from their directories, other assistants use the endpoint `https://mcp.scribe-mail.com/mcp`, and sign-in is OAuth with no API key. The assistant acts as the signed-in admin in one workspace: reads such as "which signatures are published and are any integrations failing?" run immediately, and every create, update, publish or delete asks for confirmation. Decide who may connect, keep integrations and directory data in their source systems, and log what changes. *Last reviewed: October 2026. Covers the Scribe hosted MCP server (57 tools in 15 areas), the Scribe CLI's local MCP server, and connection steps for Claude, ChatGPT, Microsoft Copilot, Gemini Enterprise, Cursor, Claude Code and Codex.* This is the hands-on guide for IT admins and marketing operations leads who want to run signature audits and routine changes from an AI assistant instead of an admin console. It covers connecting each assistant, what the connection can and cannot do, copy-paste audit workflows built on the documented tools, change workflows with an approval step, and the governance rules worth writing down before anyone connects. For the definition of an email signature MCP server and a comparison of which vendors offer one, read [what is an email signature MCP server](https://www.scribe-mail.com/en-US/email-signature-mcp-server). For the product overview, see [Scribe MCP](https://www.scribe-mail.com/en-US/mcp). ### What can an AI assistant do with your email signatures? Once connected, the assistant calls the same operations an admin performs in the dashboard. Scribe's MCP server exposes 57 tools across signatures, reply and internal variants, recipients, teammates, emails, Smart Fields, folders, assets, integrations, analytics, visitors, marketing campaigns, the workspace and billing documents ([Scribe MCP tools reference](https://help.scribe-mail.com/en/ai-agents/tools)). Each tool is marked by access level: - **Read** tools, such as `list_signatures`, `list_teammates`, `list_integrations` and `get_analytics_clicks`, run automatically and never change data. - **Write** tools, such as `create_signature`, `publish_signature`, `update_teammate` and `schedule_marketing_campaign`, ask you to confirm first. - **Delete** tools, such as `delete_signature` and `delete_teammate`, also ask you to confirm and are destructive. Every action is scoped to the workspace you signed in to. In practice IT uses the connection for three jobs: audits that would otherwise mean exporting and cross-referencing lists, bulk fixes such as filling missing titles, and reporting for marketing. Design work also fits, because `create_signature` and `update_signature` stage changes as a draft until someone publishes. If you would rather not connect an outside assistant, the [Scribe AI agent](https://www.scribe-mail.com/en-US/scribe-ai-agent) handles many of the same requests inside the Scribe web app, with nothing to connect. Owners and admins on the Business and Enterprise plans, and during the free trial, open it with the **Ask AI** button or ⌘J (Ctrl+J on Windows). It reads your signatures, teammates, Smart Fields, campaigns, integrations and analytics, builds signature drafts in the editor, and shows an approval card before any change outside the editor. It never changes billing, manages members, sets up SSO or deletes in bulk, and it isn't available in the desktop app or the Outlook add-in ([Scribe AI agent documentation](https://help.scribe-mail.com/en/scribe-ai-agent)). Use MCP when you want Scribe inside the assistant your team already works in, or in scripts. ### Who should connect, and with which account? Settle this before the first connection, because the assistant inherits the identity of whoever signs in. - **The connection acts as you.** Scribe's FAQ says the connection acts as you in one workspace, can read signatures, teammates, Smart Fields, folders, assets, integrations, campaigns and analytics, and makes changes only after you confirm each write ([Scribe MCP FAQ](https://help.scribe-mail.com/en/ai-agents/faq)). - **Only admins can manage the workspace.** In Scribe, Owners and Admins manage signatures, campaigns and settings, while the Member role can only edit and install its own signature ([Scribe members and roles](https://help.scribe-mail.com/en/members)). Give the connection to the same small group that already holds Admin. - **The CLI has explicit requirements.** The signed-in member must be a workspace owner or admin, the plan must include API access, and one login is bound to one workspace ([Scribe CLI](https://help.scribe-mail.com/en/ai-agents/cli)). - **No API keys sit in the assistant.** Every connection signs in with your Scribe account through OAuth and forwards your own access token ([Scribe MCP FAQ](https://help.scribe-mail.com/en/ai-agents/faq)). - **Several workspaces mean several connections.** Agencies and groups with one workspace per brand should connect each one deliberately, and name the workspace in every prompt. One more decision belongs here: the assistant's own data terms. Teammate names, emails, phone numbers and Smart Field values returned by read tools pass through the AI provider you use. Use the business or enterprise tier your company has already approved for internal data, not a personal account. ### How do you connect Claude? Scribe is listed in the Claude directory as Scribe Mail, and it works on all Claude plans on web and desktop ([Scribe: connect your assistant](https://help.scribe-mail.com/en/ai-agents/connect)). 1. Open the [Scribe Mail listing in the Claude directory](https://claude.ai/directory/scribe-mail) and click **Connect to Claude**. 2. Sign in with your Scribe account if prompted, choose the organization, review the access, and click **Allow access**. 3. The listing shows **Connected**. Open a new chat and ask Claude to use the Scribe connector. For Claude Code, add the hosted server and check it, then sign in on first use: ``` claude mcp add --transport http scribe https://mcp.scribe-mail.com/mcp claude mcp list ``` ### How do you connect ChatGPT? Scribe is in the ChatGPT plugin store, so no Developer Mode is needed. Sign in to ChatGPT on the web first ([Scribe: connect your assistant](https://help.scribe-mail.com/en/ai-agents/connect)). 1. Open the Scribe plugin page, or open **Plugins** in the sidebar and search for Scribe, then click **Install plugin**. 2. In **Add Scribe to ChatGPT**, click **Sign in with Scribe**, sign in, review the access and click **Allow access**. 3. In any chat, type `@Scribe` followed by your request, or select the Scribe plugin from the plus menu. ### How do you connect Microsoft Copilot, Gemini and other assistants? **Microsoft Copilot** is a two-role setup. An admin or maker builds a Scribe agent once in Copilot Studio, then the team chats with the published agent. Plain Copilot chat doesn't get the Scribe tools on its own. Each user needs a Microsoft 365 Copilot seat, the builder needs Copilot Studio capacity, and the agent needs generative orchestration ([Scribe: connect your assistant](https://help.scribe-mail.com/en/ai-agents/connect)). 1. In Copilot Studio, open or create an agent, then go to **Tools**, **Add a tool**, **New tool**, **Model Context Protocol**. 2. Set the server name to `Scribe`, add a description, and paste `https://mcp.scribe-mail.com/mcp` as a streamable endpoint. 3. Set authentication to **OAuth 2.0** with **Dynamic discovery**, since Scribe supports OAuth dynamic client registration. Create and enable the tool. 4. Enable generative orchestration, publish the agent, and make it available in Microsoft Teams or the Microsoft 365 Copilot app under **Channels**. These steps follow Microsoft's [add an existing MCP server to an agent](https://learn.microsoft.com/en-us/microsoft-copilot-studio/mcp-add-existing-server-to-agent) guide. Scribe notes that a tenant-wide federated connector surfaces Scribe for retrieval in Copilot chat, but the published-agent route is what enables actions such as creating signatures. **Gemini** is set up by a Google Workspace admin in Gemini Enterprise from the Google Cloud console: add a custom MCP server data store with the Scribe URL, register an OAuth client and authorize it, then enable the Scribe tools for users. **Cursor, Codex and other clients** take the same endpoint. For Cursor, add this to `~/.cursor/mcp.json` (all projects) or `.cursor/mcp.json` (one project), reload, and sign in on connect: ``` { "mcpServers": { "scribe": { "type": "http", "url": "https://mcp.scribe-mail.com/mcp" } } } ``` For Codex: ``` codex mcp add scribe --url https://mcp.scribe-mail.com/mcp ``` Scribe also documents flows for Mistral Vibe, Grok, Qwen Code, Hermes and OpenClaw. If you add Scribe by URL and the tools don't appear, check that your assistant plan allows custom connectors; some assistants gate them behind paid or developer settings ([Scribe MCP troubleshooting](https://help.scribe-mail.com/en/ai-agents/troubleshooting)). ### How do you run Scribe tools from the terminal or a local agent? The Scribe CLI (`@scribemail/cli`, MIT licensed) serves the same tools as the hosted server to any agent that can launch a command, and turns every tool into a shell subcommand with JSON output ([Scribe CLI documentation](https://help.scribe-mail.com/en/ai-agents/cli), [Scribe CLI page](https://www.scribe-mail.com/en-US/cli)). It needs Node.js 20 or newer. ``` npm install -g @scribemail/cli scribe login # opens your browser, no API key scribe whoami # signed-in user, workspace and token state claude mcp add --scope user scribe -- scribe mcp ``` Credentials are stored in `~/.config/scribe/credentials.json` with owner-only permissions and refresh automatically. Exit codes are `0` for success, `1` for an API or tool error, `2` for a usage error and `3` when not signed in, which makes the CLI usable in scheduled scripts. On a remote machine, forward the callback port and use `scribe login --no-browser`. Use the hosted endpoint for chat assistants and the CLI for coding agents and scripts. ### Which audits can IT run from an assistant? Each workflow below lists the prompt, the tools the assistant should call, and what to check in the answer. All of them are read-only, so nothing changes until you ask for a fix. Scribe's skill files describe the same patterns, and you can paste the core Scribe skill into your assistant so it uses the fewest calls ([Scribe skills](https://help.scribe-mail.com/en/ai-agents/skills)). #### 1. Deployment health ``` Audit our Scribe workspace. List every signature, say whether it is published and installation is activated, how many recipients each one covers, and whether any integration is in an error state. Put the result in a table and list the problems first. ``` The assistant calls `list_signatures`, then `list_signature_recipients` for each signature, then `list_integrations`, which returns each integration's status (active or error) and any error details. An integration in error is the most urgent finding: when Scribe loses access to a connected integration, installs and teammate syncs through it pause until an admin reconnects ([Scribe webhook events](https://help.scribe-mail.com/webhooks/events)). Reconnecting happens in the dashboard; the API and MCP can read integrations but never run OAuth. For per-mailbox installation state, with the device, email client and a failure code such as `user_not_found` or `forbidden`, use the CLI command `scribe signatures installations` or the API endpoint `GET /v1/signature_installations?status=failed`. See the Handbook guide to [the signature API and webhooks](https://www.scribe-mail.com/en-US/handbook/email-signature-api-webhooks). #### 2. Missing teammate data ``` List teammates who are missing a job title, a phone number or a LinkedIn URL. Group them by department and include their primary email. Don't change anything. ``` The assistant calls `list_smart_fields` to find the field catalog, then `list_teammates`, which returns each teammate's emails and Smart Field values. Missing data matters because Scribe doesn't render a block whose Smart Field is empty ([Scribe Smart Fields](https://help.scribe-mail.com/en/smart-fields)), so a missing title or license number vanishes rather than showing as a gap. Fix the gap in the right place. If the field syncs from Microsoft Entra ID, Google Workspace or an HRIS, correct it in that system, because directory data flows one way into Scribe and the API doesn't write back to synced directory fields ([Scribe API use cases](https://help.scribe-mail.com/api-reference/use-cases)). Use `update_teammate` only for manual Smart Fields stored in Scribe. Related reading: [Entra ID attributes](https://www.scribe-mail.com/en-US/handbook/entra-id-email-signatures) and [HRIS as the source of truth](https://www.scribe-mail.com/en-US/handbook/hris-email-signatures). #### 3. Assignment coverage ``` Which teammates are not assigned to any signature? Which directory groups or org units does each signature target, and is any signature set to auto-assign future teammates? ``` The assistant compares `list_teammates` with `list_signature_recipients` (which returns the targeting rules) and `list_integration_entities` (directory org units and groups). This catches the new office or acquired team that never got a template. Remember the billing side: in Scribe a paid user is a teammate assigned to a signature, so unassigned people cost nothing, and assigned people who never installed still count ([Scribe billing](https://help.scribe-mail.com/en/pricing)). #### 4. What a recipient actually sees ``` Show me the real installed signature HTML for jordan@acme.com on the "Sales 2026" signature, and tell me if the phone number, title and disclaimer are present. ``` `get_signature_html` returns the live HTML for a specific recipient with their real values, while `preview_signature` renders a draft with placeholder values. Use the first for audits and complaints ("my title is wrong"), the second before publishing. #### 5. Policy check ``` Compare every published signature with this policy: logo, name, title, phone, legal disclaimer at the bottom, at most one banner, no personal social links. List each signature that breaks a rule and why. ``` This works because the assistant can read each signature's content tree. Paste your [email signature policy](https://www.scribe-mail.com/en-US/handbook/email-signature-policy) into the prompt, or keep it in a project or skill so every audit uses the same rules. For regulated firms, add the disclosure rules from the [disclaimers guide](https://www.scribe-mail.com/en-US/handbook/email-disclaimers) or the [financial services guide](https://www.scribe-mail.com/en-US/handbook/financial-services-email-signatures). ### How do you make changes safely from an assistant? Writes always pause for confirmation, but a confirmation dialog for each call is not a review process on its own. Use a draft, preview, approve, publish sequence. 1. **Draft.** "Create a signature called Support 2026 based on Sales 2026, without the banner. Don't publish it." The assistant calls `get_content_schema` first, then `create_signature`, which stages content as a draft. 2. **Preview.** "Preview the draft and show me the HTML for one support teammate." (`preview_signature`.) 3. **Assign.** "Target it at the Support group in Entra ID and auto-assign future members." (`add_signature_recipient_entities`, `set_signature_recipient_rules`.) 4. **Publish.** "Publish Support 2026." `publish_signature` makes the draft live and installs it, so this is the step to approve deliberately. Campaigns follow the same pattern: `create_marketing_campaign` creates a draft with a name and time window, and `schedule_marketing_campaign` activates it. Pause and resume are separate writes. The Handbook guide to [banner campaigns](https://www.scribe-mail.com/en-US/handbook/email-signature-banner-campaigns) covers targeting and measurement. Reply and internal variants apply only on paid plans with Microsoft 365 or with server-side installation on Google Workspace or Microsoft 365, not with the standard Gmail integration ([Scribe signature variants](https://help.scribe-mail.com/en/signature-variants)). When variants aren't available in the workspace, variant writes return a 409 `variants_unavailable` ([Scribe MCP tools reference](https://help.scribe-mail.com/en/ai-agents/tools)). For a rebrand or a large reassignment, have the assistant produce the plan as a table first, review it with the owner of the change, then run it in batches by folder or department. The [rollout playbook](https://www.scribe-mail.com/en-US/handbook/email-signature-rollout-playbook) describes the pilot-first sequence. ### How do you report on signature performance from an assistant? ``` Rank our signatures by clickthrough rate over the last 90 days, with views and clicks, then show week-by-week clicks for the top one. ``` `get_analytics_views` and `get_analytics_clicks` return a time series or a ranked breakdown grouped by signature, campaign, teammate, link or country. There is no clickthrough-rate field in the MCP tools, so the assistant computes clicks divided by views ([Scribe MCP tools reference](https://help.scribe-mail.com/en/ai-agents/tools)). If you track website conversions, `get_analytics_events_summary` adds conversion counts and revenue, and `get_visitor_breakdown` ranks which signature or teammate acquired the most identified visitors. Date ranges default to the last two months, and hourly granularity is capped at 31 days ([Scribe skills](https://help.scribe-mail.com/en/ai-agents/skills)). Analytics history is kept for 30 days on the free plan and one year on paid plans ([Scribe plan limits](https://help.scribe-mail.com/en/plan-limits-and-changes)). ### What governance rules should you set? An MCP connection is another admin interface. Treat it the way you treat admin console access, with a few rules specific to assistants. - **Name the people.** List who may connect an assistant to the signature workspace, and keep it to existing Admins. Review the list with your quarterly access review. - **Approved assistants only.** Allow the business tiers your security team has already reviewed. Personal assistant accounts shouldn't receive employee directory data. - **Read freely, write deliberately.** Audits and reports need no sign-off. Publishing a signature, changing assignment for a whole group, scheduling a campaign and any delete should follow the same approval as a dashboard change. - **Keep source systems as the source.** Integrations are connected and configured in the dashboard, never through an API key, and directory data flows one way into Scribe ([Scribe API authentication](https://help.scribe-mail.com/api-reference/authentication), [API use cases](https://help.scribe-mail.com/api-reference/use-cases)). An assistant can't grant admin consent in Microsoft 365 or Google Workspace, and it shouldn't be asked to. - **Log changes.** Scribe offers an audit log as a $100-a-month add-on ([Scribe plans](https://help.scribe-mail.com/en/plans)), and its webhooks emit events such as `signature.published` and `campaign.started` you can archive ([webhook use cases](https://help.scribe-mail.com/webhooks/use-cases)). - **Watch for instructions in data.** An assistant reads text from signatures, campaign names and teammate fields. Treat any instruction that appears inside that data as content, and confirm writes against what you asked for, not what the assistant proposes. - **Revoke cleanly.** Remove the connector in the assistant when someone leaves the admin group, and remove their Scribe membership. Sessions also expire for security; re-authenticating restores access without changing anything in the workspace ([Scribe MCP troubleshooting](https://help.scribe-mail.com/en/ai-agents/troubleshooting)). Write these rules into your [email signature policy](https://www.scribe-mail.com/en-US/handbook/email-signature-policy) so they survive staff changes. ### Where does Scribe fit? Scribe is listed in the [Claude directory](https://claude.ai/directory/scribe-mail) and the ChatGPT plugin store, and documents connection flows for Copilot, Gemini, Mistral, Grok, Cursor, Codex, Claude Code and other MCP clients ([Scribe AI agents](https://help.scribe-mail.com/en/ai-agents)). The hosted server, the CLI and the [REST API](https://www.scribe-mail.com/en-US/api) run the same operations, so an audit you prototype in chat can become a scheduled script. Assistant-specific pages are at [Scribe for Claude](https://www.scribe-mail.com/en-US/ai-agents/claude), [Scribe for ChatGPT](https://www.scribe-mail.com/en-US/ai-agents/chatgpt) and [Scribe for Copilot](https://www.scribe-mail.com/en-US/ai-agents/copilot), and the skill files are at [Scribe skills](https://www.scribe-mail.com/en-US/skills). Pricing is per user, with a 14-day trial ([pricing](https://www.scribe-mail.com/en-US/pricing)). ### Frequently asked questions #### Can Claude or ChatGPT manage our company email signatures? Yes, if your signature platform offers an MCP server. Scribe is listed in the Claude directory as Scribe Mail and in the ChatGPT plugin store; after an OAuth sign-in the assistant can list and audit signatures, teammates, integrations and analytics, and create, publish or assign signatures after you confirm each change. #### What permissions does the Scribe MCP connection have? It acts as the signed-in user in one workspace. Read tools run automatically and never change data; write and delete tools ask for confirmation first. No API key is created or stored in the assistant. Only workspace Owners and Admins can manage signatures, campaigns and settings, so connect with an Admin account. #### Can an AI assistant connect Microsoft 365 or Google Workspace to Scribe? No. Integrations are connected and configured in the Scribe dashboard. The API and MCP tools can read integrations and their status, including errors, but cannot activate, edit or remove them, and an assistant can't grant admin consent in your tenant. #### Does Microsoft Copilot work with the Scribe MCP server? Yes, through Copilot Studio. An admin or maker adds Scribe as a Model Context Protocol tool with the URL https://mcp.scribe-mail.com/mcp and OAuth 2.0 dynamic discovery, publishes the agent, and makes it available in Teams or the Microsoft 365 Copilot app. Plain Copilot chat doesn't get the Scribe tools on its own. #### How do I find teammates with missing signature data? Ask: "List teammates who are missing a job title or phone number." The assistant calls list_smart_fields and list_teammates and returns the gaps without changing anything. Fix synced fields in Entra ID, Google Workspace or your HRIS, since directory data flows one way into Scribe; use update_teammate only for manual fields. #### Can the assistant check whether signatures are installed in each mailbox? The MCP tools report which signatures are published, who they're assigned to and whether integrations are failing. Per-mailbox installation state, with device, email client and failure code, is available from the Scribe CLI (scribe signatures installations) and the API endpoint GET /v1/signature_installations. #### Is there an audit trail of changes made through an assistant? Scribe offers an audit log as a $100-a-month add-on on any plan, and its webhooks emit events such as signature.published and campaign.started that you can archive. Confirm with Scribe how MCP-initiated changes are attributed in the audit log before relying on it for compliance. #### What is the difference between the hosted MCP server and the Scribe CLI? The hosted server at https://mcp.scribe-mail.com/mcp is for chat assistants such as Claude on the web, ChatGPT and Copilot. The CLI (@scribemail/cli) serves the same tools locally over stdio for coding agents such as Claude Code and Cursor, and turns each tool into a shell command for scripts. Both sign in with your Scribe account. #### Does Scribe have an AI assistant built in? Yes. The [Scribe AI agent](https://www.scribe-mail.com/en-US/scribe-ai-agent) sits on every page of the Scribe web app, opened with the Ask AI button or ⌘J (Ctrl+J on Windows). Owners and admins on the Business and Enterprise plans can ask questions, build signatures and approve changes there without connecting an outside assistant. The MCP server is for using Scribe from Claude, ChatGPT, Copilot or another assistant you already use. ### Related Handbook guides - [Automate signatures with the API and webhooks](https://www.scribe-mail.com/en-US/handbook/email-signature-api-webhooks) - [Email signature policy template](https://www.scribe-mail.com/en-US/handbook/email-signature-policy) - [Rollout and rebrand playbook](https://www.scribe-mail.com/en-US/handbook/email-signature-rollout-playbook) - [Microsoft 365 company-wide signatures](https://www.scribe-mail.com/en-US/handbook/microsoft-365-email-signatures) - [Google Workspace company-wide signatures](https://www.scribe-mail.com/en-US/handbook/google-workspace-email-signatures) - [Signature banner campaigns and attribution](https://www.scribe-mail.com/en-US/handbook/email-signature-banner-campaigns) ### Law Firm Email Signatures and Disclaimers: An IT and Marketing Guide (2026) Source: https://www.scribe-mail.com/en-US/handbook/law-firm-email-signatures Topic: By industry Published: 2026-10-24 For law firm IT, marketing and risk teams: what attorney signatures must include under the advertising rules, what privilege footers can and can't do, multi-office and SRA requirements, banners, and firm-wide Microsoft 365 deployment. > **TL;DR:** A law firm signature is a communication about the firm's services, so the lawyer advertising rules apply to it: it must not be false or misleading, specialist claims are restricted, and promotional content needs a responsible lawyer named. Some states add more; New York, for example, requires "ATTORNEY ADVERTISING" in the subject line of email that is an advertisement. Privilege and confidentiality footers don't create privilege, but a short one helps put a mistaken recipient on notice. UK firms regulated by the SRA must show their SRA number and "authorised and regulated by the Solicitors Regulation Authority" on emails. Manage all of it centrally: per-lawyer admissions from directory fields, per-office and per-entity templates, banners only after review, and a deployment that covers phones and keeps the filed copy in mind. *Last reviewed: October 2026.* **This is general information, not legal advice. Professional conduct rules differ by state and country and change over time; confirm the rules for each jurisdiction where your lawyers are admitted and your offices are located.** The ABA Model Rules are cited as the common baseline; your state's version controls. This guide is for the IT directors, marketing and business development teams, and general counsel or risk partners who run email signatures at law firms with more than a handful of lawyers. It covers what a firm signature should contain under the professional rules, what privilege disclaimers can and can't do, how to handle multi-office and multi-entity firms, how to use banners without creating advertising problems, and how to deploy on Microsoft 365, which most firms use. For disclaimer rules outside legal practice, see the Handbook's [email disclaimers guide](https://www.scribe-mail.com/en-US/handbook/email-disclaimers). ### What must a law firm email signature include? #### Signatures are communications about legal services Under ABA Model Rule 7.1, a lawyer must not make a false or misleading communication about the lawyer or the lawyer's services, and the comment states that firm names, letterhead and professional designations are communications concerning a lawyer's services ([ABA Model Rule 7.1, comment [5]](https://www.americanbar.org/groups/professional_responsibility/publications/model_rules_of_professional_conduct/rule_7_1_communication_concerning_a_lawyer_s_services/comment_on_rule_7_1/)). An email signature is the modern letterhead, so the same reasoning applies. Rule 7.2 adds two rules that matter for signatures ([ABA Model Rule 7.2](https://www.americanbar.org/groups/professional_responsibility/publications/model_rules_of_professional_conduct/rule_7_2_advertising/)): - **Specialist claims (7.2(c)).** A lawyer may not state or imply certification as a specialist unless certified by an organization approved by a state authority or accredited by the ABA, and the certifying organization is clearly named in the communication. "Board Certified in Civil Trial Law, [certifying body]" is acceptable where true; "Personal injury specialist" on its own is the kind of line to remove. - **Responsible lawyer (7.2(d)).** Any communication made under Rule 7.2 must include the name and contact information of at least one lawyer or law firm responsible for its content. A normal signature already identifies the sender; a promotional banner that links to a campaign page should keep that identification visible. #### State variations: the "Attorney Advertising" label States adopt their own versions of these rules, and some go further. New York's rules require email that is an attorney advertisement to carry "ATTORNEY ADVERTISING" in the subject line under Rule 7.1(f), and define an advertisement as a communication about the lawyer's or firm's services whose primary purpose is retention of the lawyer or firm, excluding communications to existing clients or other lawyers ([NYSBA Ethics Opinion 1016](https://nysba.org/ethics-opinion-1016/)). A signature on ordinary correspondence about a matter isn't an advertisement under that definition. A signature with a promotional banner, sent by a business development partner to prospective clients, may change the primary purpose of the message. Ask your ethics counsel where the line sits in each state you practice in, and design templates so that promotional elements appear only on the signatures and audiences you've cleared. #### Field checklist for a firm signature | Field | Why | Source | | --- | --- | --- | | Full name and post-nominals | Identity; avoid unearned titles | Directory | | Title (Partner, Associate, Of Counsel, Paralegal) | Rule 7.1: don't imply a role the person doesn't hold; non-lawyer staff must be clearly identified as such | Directory or HRIS | | Firm name and legal form (LLP, PC, PLLC) | Identification; firm-name rules | Template per entity | | Office address and phone | Contact; office of the sender, not head office, where offices differ | Directory (office field) | | Bar admissions ("Admitted in NY and NJ") | Avoid implying admission where the lawyer isn't licensed | Custom field | | Certification, with certifying body | Rule 7.2(c) | Custom field, filled only when verified | | Confidentiality or privilege notice | Notice to mistaken recipients (see below) | Template, approved by risk or GC | | Regulator statement (UK, other jurisdictions) | Mandatory where the regulator requires it | Template per entity | Per-lawyer fields like admissions don't usually exist in Entra ID. In Scribe you can create custom Smart Fields (text, image or link) whose data comes either from a connected directory or HRIS, or is stored in Scribe and filled manually or by CSV; a block whose field is empty is left out of that person's signature ([Scribe: Smart Fields](https://help.scribe-mail.com/en/smart-fields)). That lets the admissions line appear only for lawyers, and the certification line only where it's been verified. ### Privilege and confidentiality disclaimers: do they work? A footer cannot make a communication privileged. Attorney-client privilege depends on the content and circumstances of the communication, and a notice stapled to every email, including lunch orders and marketing, says little about any particular message. What footers can do: - **Put a mistaken recipient on notice.** ABA Model Rule 4.4(b) requires a lawyer who receives a document or electronically stored information relating to the representation of the lawyer's client, and knows or reasonably should know it was inadvertently sent, to promptly notify the sender ([ABA Model Rule 4.4](https://www.americanbar.org/groups/professional_responsibility/publications/model_rules_of_professional_conduct/rule_4_4_respect_for_rights_of_third_persons/)). A clear notice makes "should have known" easier to establish. - **Support the "reasonable steps" story.** In federal proceedings, an inadvertent disclosure doesn't waive privilege if the holder took reasonable steps to prevent it and promptly took reasonable steps to rectify it ([Federal Rule of Evidence 502(b)](https://www.law.cornell.edu/rules/fre/rule_502)). A footer is a minor part of that; how the firm handles email and responds to a misdirected message matter far more. - **Show the firm takes confidentiality seriously.** Model Rule 1.6(c) requires reasonable efforts to prevent the inadvertent or unauthorized disclosure of client information ([ABA Model Rule 1.6](https://www.americanbar.org/groups/professional_responsibility/publications/model_rules_of_professional_conduct/rule_1_6_confidentiality_of_information/)). ABA Formal Opinion 477R treats unencrypted email as generally acceptable for routine communication, with stronger measures such as encryption warranted for especially sensitive information ([ABA Formal Opinion 477R](https://www.americanbar.org/content/dam/aba/administrative/professional_responsibility/ethics-opinions/aba-formal-opinion-477.pdf)). A footer is not one of those measures. Practical rules for firm footers: 1. **Keep it short.** Two sentences beat a paragraph. Readers and judges skim boilerplate. 2. **External only.** Use an internal variant without the notice for mail between firm lawyers and staff. 3. **Don't put it on marketing.** A privilege notice on a newsletter or event invitation undermines the notice on real advice. 4. **Label privileged content in the message,** for example in the subject line or first line ("Privileged and confidential: attorney-client communication"), when the communication really is privileged. Template (adapt with your risk partner or GC): ``` This email is from [Firm name] and may contain confidential or privileged information. If you received it in error, please tell the sender and delete it without reading, copying or forwarding it. ``` More wording options are in our [confidentiality disclaimer samples](https://www.scribe-mail.com/en-US/blog/4-essential-confidentiality-disclaimer-samples-for-your-emails). ### Multi-office, multi-jurisdiction and multi-entity firms - **Office-specific signatures.** Each lawyer's signature should show the office they work from. Pull the office from the directory rather than building one template per office by hand. - **Jurisdictional limitations.** The ABA Model Rules say a firm with offices in more than one jurisdiction may use the same name in each ([Rule 7.1, comment [6]](https://www.americanbar.org/groups/professional_responsibility/publications/model_rules_of_professional_conduct/rule_7_1_communication_concerning_a_lawyer_s_services/comment_on_rule_7_1/)). Several states still have rules or comments requiring a firm to show the jurisdictional limitations of lawyers who aren't licensed where their office is located, and lawyers often add lines such as "Admitted in California only" or "Not admitted in the District of Columbia" for that reason. Fill these from the admissions field so they're never forgotten. - **Remote lawyers.** ABA Formal Opinion 495 addresses lawyers who work remotely from a jurisdiction where they aren't admitted, and cautions against holding out a presence there, for example by listing a local address ([ABA Formal Opinion 495](https://www.americanbar.org/content/dam/aba/administrative/professional_responsibility/ethics-opinions/aba-formal-opinion-495.pdf)). Signatures for remote lawyers should show the firm office they're attached to, not their home city. Check your states' own rules and opinions on remote practice. - **International firms and separate entities.** Many firms practice through several legal entities (a US LLP, a UK LLP, a European partnership). Each entity's employees need that entity's identification block, chosen by who employs the sender. In the UK, an SRA-authorised body's letterhead and emails must show its SRA authorisation number and the words "authorised and regulated by the Solicitors Regulation Authority" ([SRA Transparency Rules, rule 4.2](https://www.sra.org.uk/solicitors/standards-regulations/transparency-rules/)), and UK company and LLP disclosure rules also apply; see the [disclaimers guide](https://www.scribe-mail.com/en-US/handbook/email-disclaimers). In Scribe, each template can be assigned by Smart Field condition (for example, office or company from Entra ID), by group or by administrative unit, with an option to auto-assign it to future hires, and signature priority settles which template wins when a lawyer matches more than one ([Scribe: assign teammates](https://help.scribe-mail.com/en/assign-teammates-to-a-signature); [signature priority](https://help.scribe-mail.com/en/signature-priority)). ### Practice-area banners, awards and rankings Signature banners are attractive to business development teams and the part of the signature most likely to cause a professional-conduct question. - **Rankings and awards.** The ABA comment warns that truthful reports of results can mislead if they create unjustified expectations, and that unsubstantiated comparisons with other lawyers can be misleading; appropriate disclaimers or qualifying language may prevent that ([Rule 7.1, comment [3]](https://www.americanbar.org/groups/professional_responsibility/publications/model_rules_of_professional_conduct/rule_7_1_communication_concerning_a_lawyer_s_services/comment_on_rule_7_1/)). Some states require specific disclosures about the basis of an award or ranking. Show awards with the year and the awarding body, and only where your state's rules allow. - **Case results and testimonials.** Keep them out of signatures. They're the content most likely to need state-specific disclaimers, and a signature has no room for them. - **Audience targeting.** A thought-leadership banner (a new client alert, a webinar) is lower-risk than a "hire us" banner. Restrict promotional banners to business development staff and to external, non-client correspondence where possible, and never put them on mail to opposing counsel or courts. - **Review and retention.** Treat signature banners as advertising for review purposes. Some states require advertising to be retained or filed; keep a copy of each banner with its dates of use. In Scribe, banners run as marketing campaigns with start and end dates, targeted by signature or by Smart Field such as department or location ([Scribe: marketing campaigns](https://help.scribe-mail.com/en/marketing-campaign)); record the approval yourself, because an approval step isn't part of the documented workflow. See [banner campaigns](https://www.scribe-mail.com/en-US/handbook/email-signature-banner-campaigns) for the mechanics. ### Deploying firm-wide on Microsoft 365 Most firms run Exchange Online and Outlook, often with a document management system's Outlook add-in for filing email to matters. Signature deployment choices interact with both. | Option | Covers | What it means for a firm | | --- | --- | --- | | Client-side add-in | Outlook desktop, web, iOS and Android (supported builds) | Lawyers see the signature while writing; the Sent Items copy, and so the copy filed to the matter, matches what the recipient got; email doesn't pass through the vendor | | Server-side relay | Every client and device, including Apple Mail and mail sent through the mailbox by other tools | Full coverage, but the signature is added after sending, so the Sent Items copy doesn't show it ([Scribe: Microsoft 365 server-side](https://help.scribe-mail.com/en/integrations/signatures/microsoft-365-server-side)); outbound client email transits the vendor | | Both | Client-side where supported, server-side for the rest | Scribe documents that when both are connected it defaults to client-side so people see their signature, and the server side skips messages that already carry it | Two firm-specific points follow: - **The filed record.** If your DMS files the Sent Items copy, a server-side-only deployment means the filed email lacks the signature and notice the client saw. If the matter file must reflect exactly what was sent, use client-side for Outlook and keep server-side as the fallback for phones. - **Vendor due diligence.** With server-side routing, client confidential email passes through the signature vendor. Scribe's documentation states that the connection is TLS-enforced in both directions, that its return connector accepts only Scribe's two fixed IP addresses, that message content is passed through unchanged, and that Scribe "cannot read or edit your emails" (same source); its Trust Center lists SOC 2 Type II ([Scribe Trust Center](https://security.scribe-mail.com)). Your risk team will also want to know whether content is stored on the relay, where it's hosted, and the subprocessors involved, which the public documentation doesn't spell out. Rule 1.6(c) and Opinion 477R frame that review as part of the firm's reasonable efforts. Mobile matters: client-side installation doesn't reach Gmail for Android or Apple Mail ([Scribe: mobile](https://help.scribe-mail.com/en/do-scribe-email-signatures-work-on-mobile)), so either standardize lawyers on Outlook mobile through device management or add server-side coverage. Setup steps are in the [Microsoft 365 guide](https://www.scribe-mail.com/en-US/handbook/microsoft-365-email-signatures), the trade-offs in [client-side vs server-side signatures](https://www.scribe-mail.com/en-US/handbook/client-side-vs-server-side-email-signatures), and delegated, shared and assistant mailboxes in [shared mailbox and alias signatures](https://www.scribe-mail.com/en-US/handbook/shared-mailbox-alias-reply-signatures). ### Who should approve signature content at a firm? 1. **General counsel or risk partner:** confidentiality notice, regulator statements, the rules for admissions and certification lines, and which banners count as advertising. 2. **Marketing or business development:** design, banners and campaign calendar, inside the rules above. 3. **IT:** deployment, coverage of phones and other tools, directory fields, and the vendor security review. 4. **HR or lawyer onboarding:** keeping admissions, titles and offices current in the source system when lawyers join, are promoted, are admitted in a new state or leave. Write these into a firm signature policy; a template is in the [email signature policy guide](https://www.scribe-mail.com/en-US/handbook/email-signature-policy). ### Frequently asked questions #### What should an attorney email signature include? Name, title, firm name and legal form, office address and phone, and where relevant bar admissions and any certification with the certifying body named. Add a short confidentiality notice on external email and any regulator statement your jurisdiction requires. This is general information, not legal advice. #### Is an attorney-client privilege disclaimer in an email legally binding? No. A footer can't make a communication privileged; privilege depends on the communication itself. A short notice helps put a mistaken recipient on notice, which supports ABA Model Rule 4.4(b) and the reasonable-steps analysis under Federal Rule of Evidence 502(b). #### Does a lawyer's email signature count as advertising? Signatures are communications about a lawyer's services, so the truthfulness rules apply. Whether an email is an advertisement depends on state rules; New York, for example, treats communications whose primary purpose is retention as advertisements and requires ATTORNEY ADVERTISING in the subject line. Promotional banners can change that analysis. #### What must a UK solicitors' firm put in its emails? Under SRA Transparency Rules rule 4.2, an authorised body's letterhead and emails must show its SRA authorisation number and the words "authorised and regulated by the Solicitors Regulation Authority". Company or LLP registration details under the UK disclosure regulations also apply. #### Can law firms put awards and rankings in email signatures? Carefully. The ABA comment to Rule 7.1 warns that unsubstantiated comparisons can mislead, and some states require specific disclosures about rankings. Show the year and awarding body, have the risk partner approve each banner, and keep a copy with its dates of use. #### Should law firms use server-side email signatures? Server-side covers every device, but the Sent Items copy lacks the signature, so a DMS that files from Sent Items stores a different version than the client received, and client email transits the vendor. Many firms use client-side Outlook signatures with server-side only as a fallback for phones, after a vendor security review. #### How do I add bar admissions to each lawyer's signature automatically? Store admissions in a directory, HRIS or signature-tool field and bind the template to it. In Scribe, a custom Smart Field can come from a connected source or be filled in Scribe or by CSV, and the line is left out for anyone whose field is empty. ### Related Handbook guides - [Email disclaimers: legal requirements by country and industry](https://www.scribe-mail.com/en-US/handbook/email-disclaimers) - [Microsoft 365 and Exchange Online company-wide signatures](https://www.scribe-mail.com/en-US/handbook/microsoft-365-email-signatures) - [Client-side vs server-side email signatures](https://www.scribe-mail.com/en-US/handbook/client-side-vs-server-side-email-signatures) - [Email signatures for financial services](https://www.scribe-mail.com/en-US/handbook/financial-services-email-signatures) - [Email signature policy template](https://www.scribe-mail.com/en-US/handbook/email-signature-policy) ### HRIS as the Source of Truth for Email Signatures: Workday, BambooHR, Rippling, HiBob and More (2026) Source: https://www.scribe-mail.com/en-US/handbook/hris-email-signatures Topic: Employee data Published: 2026-10-24 How to keep email signature titles, departments and phone numbers correct by reading each field from the system that owns it: directory vs HRIS ownership, the 14 HR and identity tools Scribe connects to, record matching, precedence, sync timing, the employee lifecycle and unsupported HR systems. > **TL;DR:** In most companies over 100 people, HR owns job titles and departments, IT owns mailboxes, and a phone system owns direct lines. Signatures stay correct when each field is read from the system that owns it. Scribe can pull Smart Field data from 14 HR and identity tools (BambooHR, Ceridian Dayforce, ChartHop, Deel, Gusto, HiBob, Lattice, Lucca, Okta, PayFit, Rippling, UKG, Workday, Workleap Pingboard), plus phone systems, calendars and Outreach. Each Smart Field has exactly one data source, so you decide ownership field by field. Teammates themselves still come from Google Workspace, Microsoft Entra ID or Zoho Mail, and data syncs once a day or on demand. *Last reviewed: October 2026. Covers Scribe's HRIS, phone-system, calendar and sales-tool Smart Field integrations, and Microsoft Entra inbound HR provisioning.* This guide is for IT and People Ops teams who are tired of signature titles that lag behind promotions. It explains how to decide which system owns each field, which HR tools Scribe connects to and how each one is set up, how records are matched and refreshed, what happens at onboarding and offboarding, and what to do if your HRIS isn't supported. If your directory is the source of truth and you only need Microsoft's side, read [Sync signatures from Microsoft Entra ID](https://www.scribe-mail.com/en-US/handbook/entra-id-email-signatures) instead. ### Directory or HRIS: which system should own signature data? A signature is a public copy of a few employee attributes. The question is not "directory or HRIS" but "who updates this field first when it changes". In most organizations the answer looks like this: | Signature field | Usual owner | Why | | --- | --- | --- | | Name, email address, aliases | Directory (Entra ID, Google Workspace) | IT creates the mailbox; the address must match the mailbox exactly | | Job title, department, division | HRIS | Promotions and transfers are HR transactions; the directory is often updated later, or never | | Office location and address | HRIS or directory | Whichever system facilities and HR keep current | | Direct line | Phone system (Aircall, Dialpad, CloudTalk, Nextiva) | Numbers are assigned and reassigned in the phone system | | Mobile number | HRIS or the employee | Often absent from both; collect it from the person | | Booking link | Calendar tool (Calendly, Chili Piper, Cal.com) | The link belongs to the scheduling account | | Photo, pronouns, certifications | Employee or HRIS | Personal or role data the directory rarely holds | Scribe's own documentation frames HRIS sync the same way: it is useful "when your directory isn't up to date but your HRIS data is", and fields synced from an HRIS are locked on the teammate profile just like directory fields ([Teammate profile](https://help.scribe-mail.com/en/teammates/teammate-profile)). There is a second architecture worth considering if you run Microsoft 365: make Entra ID accurate by provisioning it from HR, then let the signature tool read Entra ID only. Microsoft Entra supports inbound user provisioning from cloud HR apps such as Workday and SuccessFactors, including creating accounts for new hires ([Plan cloud HR application to Microsoft Entra user provisioning](https://learn.microsoft.com/en-us/entra/identity/app-provisioning/plan-cloud-hr-provision)), and API-driven inbound provisioning for any other system of record, including CSV extracts ([API-driven inbound provisioning concepts](https://learn.microsoft.com/en-us/entra/identity/app-provisioning/inbound-provisioning-api-concepts)). Microsoft lists an Entra ID P1 or P2 license as a requirement for the cloud HR integration. The trade-off is simple: HR-to-directory provisioning fixes data for every app that reads Entra ID, while a direct HRIS connection in the signature tool fixes only signatures but takes minutes to set up. ### Which HR tools does Scribe connect to, and how is each set up? Scribe's Smart Fields page lists 14 tools in its HRIS category: BambooHR, Ceridian Dayforce, ChartHop, Deel, Gusto, HiBob, Lattice, Lucca, Okta, PayFit, Rippling, UKG, Workday and Workleap Pingboard ([Smart Fields](https://help.scribe-mail.com/en/smart-fields)). Okta is an identity provider rather than an HRIS, but it is grouped there and works the same way. Setup differs by tool, and for several of them it starts with a support request rather than a button: | Tool | How it connects | Admin role needed | Scribe doc | | --- | --- | --- | --- | | BambooHR | Subdomain plus an API key; optional custom report ID for extra and custom fields | API key access | [BambooHR](https://help.scribe-mail.com/en/integrations/smart-fields/bamboohr-smart-fields) | | Ceridian Dayforce | Activated by Scribe support | Dayforce Admin | [Dayforce](https://help.scribe-mail.com/en/integrations/smart-fields/ceridian-dayforce-smart-fields) | | ChartHop | Install the Scribe app in Apps & Bundles, then paste its API token and your org nickname | Access to Apps & Bundles | [ChartHop](https://help.scribe-mail.com/en/integrations/smart-fields/charthop-smart-fields) | | Deel | OAuth from the Deel Marketplace listing | Deel Admin | [Deel](https://help.scribe-mail.com/en/integrations/smart-fields/deel-smart-fields) | | Gusto | Activated by Scribe support | Not stated | [Gusto](https://help.scribe-mail.com/en/integrations/smart-fields/gusto-smart-fields) | | HiBob | Activated by Scribe support | Not stated | [HiBob](https://help.scribe-mail.com/en/integrations/smart-fields/hibob-smart-fields) | | Lattice | Activated by Scribe support | Not stated | [Lattice](https://help.scribe-mail.com/en/integrations/smart-fields/lattice-smart-fields) | | Lucca | Instance domain plus an API key with the Co-workers scope; listed on the Lucca Marketplace | Lucca admin | [Lucca](https://help.scribe-mail.com/en/integrations/smart-fields/lucca-smart-fields) | | Okta | An OIDC single-page app in Okta with the `okta.users.read` and `okta.schemas.read` scopes granted | Okta admin console | [Okta](https://help.scribe-mail.com/en/integrations/smart-fields/okta-smart-fields) | | PayFit | OAuth, read-only scopes | PayFit Admin | [PayFit](https://help.scribe-mail.com/en/integrations/smart-fields/payfit-smart-fields) | | Rippling | Install from the Rippling App Shop, authorize read-only scopes | Rippling Admin | [Rippling](https://help.scribe-mail.com/en/integrations/smart-fields/rippling-smart-fields) | | UKG | Activated by Scribe support | Not stated | [UKG](https://help.scribe-mail.com/en/integrations/smart-fields/ukg-smart-fields) | | Workday | Activated by Scribe support | Not stated | [Workday](https://help.scribe-mail.com/en/integrations/smart-fields/workday-smart-fields) | | Workleap Pingboard | A Pingboard API service account; paste its client ID and secret | Pingboard admin | [Pingboard](https://help.scribe-mail.com/en/integrations/smart-fields/workleap-pingboard-smart-fields) | For Workday, UKG, HiBob, Gusto, Lattice and Dayforce, Scribe's public docs stop at "contact support", so they don't say which fields are available or what access your HR admin will need to grant. Ask for that list during evaluation, and put the HRIS admin in the setup call. Where Scribe publishes a data-collection page, it lists exactly what is stored: | Tool | Fields Scribe stores (from its data-collection page) | | --- | --- | | BambooHR | Photo, first and last name, job title; work phone, extension, mobile and home phone; department, division, location; address; age and date of birth; LinkedIn, Facebook, Instagram, Twitter and Pinterest URLs. With a report ID, only the fields in that report ([source](https://help.scribe-mail.com/en/security/data-collection/bamboohr)) | | Rippling | First, last and full name, job title, work email, work location (street, city, state, zip, country code, phone, nickname) ([source](https://help.scribe-mail.com/en/security/data-collection/rippling)) | | Okta | First, last and middle name, honorific prefix and suffix, title, display name, nickname, secondary email, mobile and primary phone, address, employee number, cost center, organization, division, department, manager ([source](https://help.scribe-mail.com/en/security/data-collection/okta)) | | ChartHop | Photo, names, job title, work and mobile phone, department name, personal and work address ([source](https://help.scribe-mail.com/en/security/data-collection/charthop)) | | Dayforce | First and last name, job title, mobile phone, work location ([source](https://help.scribe-mail.com/en/security/data-collection/dayforce)) | One privacy point for your review: BambooHR's default sync stores age, date of birth and home phone, which no signature needs. BambooHR's custom report option exists for adding custom fields, but Scribe also states that with a report ID it stores only the fields in that report ([Scribe docs](https://help.scribe-mail.com/en/security/data-collection/bamboohr)). Build a report with work email plus the fields you will actually show, and you get data minimization for free. The [GDPR guide](https://www.scribe-mail.com/en-US/handbook/gdpr-email-signatures) covers the wider question. ### How are HRIS records matched to mailboxes? An HRIS doesn't create Scribe teammates. Scribe's automated teammate sources are Google Workspace, Microsoft Entra ID and Zoho Mail; manual entry and CSV upload cover the rest ([Teammates overview](https://help.scribe-mail.com/en/teammates/teammates-overview)). The HRIS then fills Smart Fields for teammates who already exist, so every HR record has to be matched to a teammate. For BambooHR, Scribe documents the rule: it matches the teammate's primary email in Scribe with the **work email** field in BambooHR. If work email is empty, the person doesn't sync, and a custom report must include work email ([BambooHR sync not working](https://help.scribe-mail.com/en/troubleshooting/bamboohr-teammate-sync-not-working)). Scribe doesn't document the matching key for the other tools; plan as if it is the work email and confirm with Scribe. Before connecting any HRIS, check three things: - Every active employee has a work email in the HRIS. - It is the **primary** address of their mailbox, not an alias or a pre-rename address. - Contractors and employees of acquired entities use the same convention, or you know which ones will not match. ### What happens when the directory and the HRIS disagree? Nothing is merged. In Scribe, each Smart Field has one **data source** and one **source field**, chosen on the Smart Fields page. A field can come from Google Workspace, Microsoft Entra ID, Zoho Mail, any connected HRIS, phone, calendar or sales tool, or from Scribe itself as a manually filled value ([Smart Fields](https://help.scribe-mail.com/en/smart-fields)). Whatever that source says is what the signature shows. That makes precedence a design decision you take once, per field: 1. List the fields your templates use (only those count; Scribe recommends marking only used fields as required). 2. For each, pick the owner from the table above and set it as the data source. Default fields such as First name, Job Position and Work phone number can't be deleted or renamed, but their data source can be changed ([Smart Fields](https://help.scribe-mail.com/en/smart-fields)). 3. Check the **Information completion** column. If the HRIS fills job title for 98% of people but the directory filled it for 70%, you have your answer. 4. Write the decision down in your [signature policy](https://www.scribe-mail.com/en-US/handbook/email-signature-policy), so nobody "fixes" a title in the wrong system. Scribe's docs don't describe a fallback, such as "use the HRIS title, and the directory title if it's empty". If a source is empty for someone, the block is left out of their signature rather than borrowed from another source ([Smart Fields](https://help.scribe-mail.com/en/smart-fields)). If you need fallback logic, ask Scribe, or fix the gap at the owning source. ### How fresh is HRIS data in the signature? Each HRIS page says changes "auto-sync to Scribe", and the Smart Fields page gives the mechanism: connected sources sync automatically once a day based on your time zone, and **Refresh** triggers a manual sync of all sources at any time ([Smart Fields](https://help.scribe-mail.com/en/smart-fields)). Hovering a field's data source icon shows when it was last refreshed. For most changes a day is fine: a promotion doesn't need to be in the signature within the hour. For the ones that do (a new executive's first day, a corrected phone number on a customer-facing team), update the HRIS and click Refresh. If you chose HR-to-Entra provisioning instead, add that pipeline's own interval in front of the signature sync. ### How do signatures follow onboarding, transfers and offboarding? Put together, the employee lifecycle runs like this: | Lifecycle event | What has to happen | How it happens in Scribe | | --- | --- | --- | | New hire | Mailbox created by IT, HR record created by HR | Directory sync imports the teammate (auto-sync per scope); HRIS fills their fields on the next sync; a rule-based signature with "auto-assign to all future teammates" picks them up ([Assign teammates](https://help.scribe-mail.com/en/assign-teammates-to-a-signature)) | | Promotion or transfer | HR updates title and department | Smart Field values change on the next HRIS sync; the signature follows | | New phone number | Number reassigned in the phone system | Phone-system Smart Field updates on the next sync | | Departure | Account disabled, license removed | Scribe's pricing FAQ: deactivating the license in Google Workspace or Entra ID removes the signature from Scribe and the seat from billing ([pricing](https://www.scribe-mail.com/en-US/pricing)) | If other systems need to react to the same events, subscribe to Scribe's `teammate.created` and `teammate.deleted` webhooks. They fire whether the change came from the dashboard, the API or a directory sync, and Scribe's use-case page shows them driving ITSM tickets and offboarding records ([Webhook use cases](https://help.scribe-mail.com/webhooks/use-cases)). A Rippling-specific note: during installation Rippling asks who should get a Scribe account and when. Scribe's recommended answers are "Everyone except contractors" and "As soon as they've signed their offer letter or agreement" ([Rippling setup](https://help.scribe-mail.com/en/integrations/smart-fields/rippling-smart-fields)). Decide deliberately: contractors who send external email under your brand may need signatures too. ### Can phone systems, calendars and sales tools feed signatures too? Yes, through the same Smart Field mechanism ([Smart Fields](https://help.scribe-mail.com/en/smart-fields)): - **Business phone systems:** Aircall, CloudTalk, Dialpad and Nextiva, for direct lines. Aircall connects by OAuth with an Aircall admin; Dialpad is activated by support ([Aircall](https://help.scribe-mail.com/en/integrations/smart-fields/aircall-smart-fields), [Dialpad](https://help.scribe-mail.com/en/integrations/smart-fields/dialpad-smart-fields)). - **Calendars:** Cal.com, Calendly and Chili Piper, so each person's booking link stays current ([Calendly](https://help.scribe-mail.com/en/integrations/smart-fields/calendly-smart-fields), [Chili Piper](https://help.scribe-mail.com/en/integrations/smart-fields/chili-piper-smart-fields)). - **Sales execution:** Outreach. Note that this connection asks for read and write access to mailboxes, unlike the read-only HR connectors, so expect a closer look from security ([Outreach](https://help.scribe-mail.com/en/integrations/smart-fields/outreach-smart-fields)). Scribe does not pull Smart Field data from CRMs: there is no Salesforce or HubSpot data sync. Its Salesforce integration installs signatures in Salesforce on the web, set up by a Salesforce admin ([Scribe: Salesforce](https://help.scribe-mail.com/en/integrations/signatures/salesforce-client-side)); it is not a CRM data source, and there is no HubSpot integration. ### What if your HRIS isn't on the list? You still have four options, in order of how much they automate: 1. **Provision your directory from HR.** Microsoft's API-driven inbound provisioning accepts data from any system of record, including CSV or SQL exports moved by your own automation ([Microsoft Learn](https://learn.microsoft.com/en-us/entra/identity/app-provisioning/inbound-provisioning-api-concepts)). Once Entra ID is right, the [Entra ID sync](https://www.scribe-mail.com/en-US/handbook/entra-id-email-signatures) carries it into signatures. 2. **Push values with the Scribe API.** `PATCH /v1/teammates/{id}` sets a teammate's Smart Field values; an unknown field returns a 422 ([API reference](https://help.scribe-mail.com/api-reference/teammates/update-a-teammates-smart-fields)). Run it from your iPaaS when the HR record changes. Scribe's docs don't say whether the API can overwrite a field whose data source is a synced integration, so target custom fields stored in Scribe. 3. **Upload a CSV** of Smart Field values on a schedule ([Smart Fields](https://help.scribe-mail.com/en/smart-fields)). 4. **Invite teammates** to fill their own missing fields from a restricted profile view ([Smart Fields](https://help.scribe-mail.com/en/smart-fields)). ### What will security and HR ask before connecting an HRIS? - **Access level.** Rippling and PayFit setups state Scribe has read-only access ([Rippling](https://help.scribe-mail.com/en/integrations/smart-fields/rippling-smart-fields), [PayFit](https://help.scribe-mail.com/en/integrations/smart-fields/payfit-smart-fields)). API-key tools (BambooHR, Lucca, ChartHop, Pingboard) inherit the key's permissions, so create a dedicated key or service account named for Scribe; Lucca's setup asks for the Co-workers scope with "Consult / create / modify users", which is broader than reading. - **Data stored.** Use the data-collection pages above, and restrict BambooHR with a custom report. - **Certification.** Scribe states it is SOC 2 Type II compliant and publishes a [Trust Center](https://security.scribe-mail.com) ([Scribe security](https://help.scribe-mail.com/en/what-scribe-does-concerning-security)). - **Write-back.** None of the HRIS pages describes writing back to the HRIS. Synced data flows one way, into Scribe ([Teammates overview](https://help.scribe-mail.com/en/teammates/teammates-overview)). ### Where does Scribe fit? Scribe treats HR, phone and calendar tools as Smart Field sources alongside the directory, so one template can carry the HRIS title, the Aircall direct line and the Calendly link. Website pages exist for [Workday](https://www.scribe-mail.com/en-US/integrations/workday), [BambooHR](https://www.scribe-mail.com/en-US/integrations/bamboo-hr), [Rippling](https://www.scribe-mail.com/en-US/integrations/rippling), [HiBob](https://www.scribe-mail.com/en-US/integrations/hibob), [UKG](https://www.scribe-mail.com/en-US/integrations/ukg) and the others in the table. The [HR solution page](https://www.scribe-mail.com/en-US/solutions/hr) covers what People Ops can do with signatures once the data is right, and the [API](https://www.scribe-mail.com/en-US/api) covers the long tail. Plans are per user, billed only for people whose primary email has a signature ([pricing](https://www.scribe-mail.com/en-US/pricing)). ### Frequently asked questions #### Which HRIS tools can sync with Scribe email signatures? Scribe's Smart Fields documentation lists 14 tools in its HRIS category: BambooHR, Ceridian Dayforce, ChartHop, Deel, Gusto, HiBob, Lattice, Lucca, Okta, PayFit, Rippling, UKG, Workday and Workleap Pingboard. Workday, UKG, HiBob, Gusto, Lattice and Dayforce are activated through Scribe support; the others are self-serve with OAuth, an API key or a service account. #### Should job titles come from the directory or the HRIS? From whichever system HR updates first when someone is promoted, which in most companies over 100 people is the HRIS. Keep name, email and aliases on the directory, direct lines on the phone system, and booking links on the calendar tool. In Scribe each Smart Field has one data source, so you set this per field. #### What happens if the HRIS and Entra ID have different titles? Scribe doesn't merge them. Each Smart Field reads from the one data source you chose for it, and the signature shows that value. If that source is empty for a person, the block is left out of their signature rather than filled from another source. #### How does Scribe match HRIS employees to mailboxes? For BambooHR, Scribe matches the teammate's primary email with BambooHR's work email field, and employees without a work email don't sync. Scribe doesn't document the key for other tools, so make sure every HR record carries the mailbox's primary address and confirm with Scribe. #### How often does HRIS data update in signatures? Connected sources sync automatically once a day based on your workspace time zone, and an admin can click Refresh to sync all sources immediately. #### Does the HRIS create or remove teammates in Scribe? Teammates come from Google Workspace, Microsoft Entra ID or Zoho Mail, or are added manually or by CSV; HRIS integrations fill their Smart Fields. Departures are driven by the directory: Scribe's pricing FAQ says deactivating a license in Google Workspace or Entra ID removes the signature and the billed seat. #### Can Scribe pull signature data from Salesforce or HubSpot? No. Scribe has no CRM data sync and no HubSpot integration. Its Salesforce integration installs signatures in Salesforce on the web; it doesn't read CRM records into Smart Fields. #### What if our HR system isn't supported? Provision Entra ID from HR with Microsoft's API-driven inbound provisioning and sync signatures from Entra ID, push values to custom Smart Fields with Scribe's API (PATCH /v1/teammates/{id}), upload a CSV, or invite employees to fill missing fields themselves. ### Related Handbook guides - [Sync signatures from Microsoft Entra ID](https://www.scribe-mail.com/en-US/handbook/entra-id-email-signatures) - [Rollout and rebrand playbook](https://www.scribe-mail.com/en-US/handbook/email-signature-rollout-playbook) - [Google Workspace company-wide signatures](https://www.scribe-mail.com/en-US/handbook/google-workspace-email-signatures) - [Email signature API and webhooks](https://www.scribe-mail.com/en-US/handbook/email-signature-api-webhooks) - [GDPR and email signatures](https://www.scribe-mail.com/en-US/handbook/gdpr-email-signatures) ### HIPAA and Email Signatures: A Governance Guide for Healthcare Organizations (2026) Source: https://www.scribe-mail.com/en-US/handbook/healthcare-hipaa-email-signatures Topic: Compliance Published: 2026-10-24 For healthcare IT and privacy leads: what HIPAA does and doesn't say about email signatures, keeping PHI out of signatures and banners, when a signature vendor becomes a business associate, tracking on patient email, and mobile coverage. > **TL;DR:** HIPAA doesn't regulate what goes in an email signature, and it doesn't require a disclaimer. It does regulate protected health information (PHI) and every vendor that handles it. For a healthcare organization the signature questions that matter are: keep PHI out of signatures and banners, decide whether signature tracking belongs on mail to patients, and, before you route outbound email through any signature service, establish whether that vendor becomes a business associate and will sign a business associate agreement (BAA). If you can't get a BAA, use a deployment where mail never passes through the vendor. *Last reviewed: October 2026.* **This is general information, not legal advice. HIPAA obligations depend on whether you're a covered entity or business associate and on how each system handles PHI; confirm requirements for your organization and any state law with your privacy officer and counsel.** Sections of the HIPAA Rules are linked to the eCFR text, and HHS guidance to hhs.gov. This guide is for IT, security and privacy leads at hospitals, health systems, clinic groups, payers and health-tech companies who are standardizing email signatures. It covers governance: what may and may not appear in a signature, how signature vendors fit into your business associate inventory, patient-facing versus internal signatures, and mobile. For copy-ready disclaimer wording (provider, billing, business associate and patient-portal templates), use our [HIPAA email disclaimer templates](https://www.scribe-mail.com/en-US/blog/10-essential-email-disclaimers-for-hipaa-compliance); for disclaimer rules outside healthcare, the Handbook's [email disclaimers guide](https://www.scribe-mail.com/en-US/handbook/email-disclaimers). ### What does HIPAA actually say about email and signatures? Nothing about signatures specifically. Three parts of the HIPAA Rules shape how you manage them: - **Email with patients is allowed with safeguards.** HHS says covered health care providers may communicate electronically with patients, for example by email, provided they apply reasonable safeguards, such as checking the address before sending and limiting the amount or type of information in unencrypted email ([HHS FAQ: email with patients](https://www.hhs.gov/hipaa/for-professionals/faq/does-hipaa-permit-health-care-providers-to-use-email-to-discuss-health-issues-with-patients/index.html)). Patients can also request communication by alternative means or at alternative locations ([45 CFR 164.522(b)](https://www.ecfr.gov/current/title-45/subtitle-A/subchapter-C/part-164/subpart-E/section-164.522)). - **Electronic PHI needs technical safeguards.** The Security Rule requires access controls, audit controls, integrity controls and transmission security for ePHI sent over a network ([45 CFR 164.312](https://www.ecfr.gov/current/title-45/subtitle-A/subchapter-C/part-164/subpart-C/section-164.312)). A disclaimer is none of these: it's a notice to a mistaken recipient. - **Vendors that handle PHI are business associates.** A person or company that creates, receives, maintains or transmits PHI on behalf of a covered entity is a business associate ([45 CFR 160.103](https://www.ecfr.gov/current/title-45/subtitle-A/subchapter-C/part-160/subpart-A/section-160.103)), and the covered entity needs satisfactory assurances in a written contract before disclosing PHI to it ([45 CFR 164.502(e)](https://www.ecfr.gov/current/title-45/subtitle-A/subchapter-C/part-164/subpart-E/section-164.502); contract terms in [164.504(e)](https://www.ecfr.gov/current/title-45/subtitle-A/subchapter-C/part-164/subpart-E/section-164.504); Security Rule equivalent in [164.308(b)](https://www.ecfr.gov/current/title-45/subtitle-A/subchapter-C/part-164/subpart-C/section-164.308)). So the signature itself is a low-risk object. The risk sits in two places: content that someone adds to it, and the path outbound email takes through the signature vendor. ### What must not go in a healthcare email signature? A standard staff signature (name, credentials, role, department, location, work phone) is not PHI. The definition of PHI excludes employment records held by a covered entity in its role as employer ([45 CFR 160.103](https://www.ecfr.gov/current/title-45/subtitle-A/subchapter-C/part-160/subpart-A/section-160.103)), and staff contact details are about the workforce, not patients. PHI gets into signatures in less obvious ways: - **Personalized links.** A "manage your appointment" or portal link with a patient identifier, medical record number or appointment ID in the URL puts PHI into every copy of the email and into whatever system logs the click. Keep patient-facing links generic and let the patient authenticate on arrival. - **Condition-specific banners.** A banner like "Living with diabetes? Join our program" is harmless on a newsletter page. Attached to a one-to-one email from a clinician to a patient, it can imply something about the recipient's health. Keep clinical-service banners off patient-facing signatures, or restrict them to general service announcements. - **Free-text fields.** Signature fields filled from the directory sometimes carry notes someone typed into a profile. Map only the fields the template needs. - **Pasted content.** Staff who build their own signatures sometimes paste in a "PS" from a previous email. Central templates that overwrite local edits remove the problem. The minimum necessary standard requires covered entities to limit uses and disclosures of PHI to the minimum necessary for the purpose ([45 CFR 164.502(b)](https://www.ecfr.gov/current/title-45/subtitle-A/subchapter-C/part-164/subpart-E/section-164.502)). Applied to signatures, the practical reading is simple: a signature should never carry PHI at all, so nothing about it should vary by patient. #### Marketing banners and the HIPAA definition of marketing Under the Privacy Rule, "marketing" is a communication that encourages recipients to buy or use a product or service, with exceptions that include communications about the covered entity's own health-related products and services, unless the covered entity receives financial remuneration from a third party for making the communication ([45 CFR 164.501](https://www.ecfr.gov/current/title-45/subtitle-A/subchapter-C/part-164/subpart-E/section-164.501)). Using PHI for marketing generally requires the individual's authorization ([45 CFR 164.508(a)(3)](https://www.ecfr.gov/current/title-45/subtitle-A/subchapter-C/part-164/subpart-E/section-164.508)). For signatures that means: a banner promoting your own new urgent care location is a different case from a banner a device or drug manufacturer pays you to run. Route any sponsored or third-party banner to your privacy officer before it goes on patient-facing email. #### Substance use disorder programs Programs covered by 42 CFR Part 2 have an additional requirement: disclosures made with patient consent must be accompanied by a specific notice about redisclosure ([42 CFR 2.32](https://www.ecfr.gov/current/title-42/chapter-I/subchapter-A/part-2/subpart-C/section-2.32)). Some programs place that notice in a footer on email that may contain Part 2 records. Whether a footer is the right vehicle, and the exact wording, is a question for counsel; if you do use it, apply it centrally to the relevant mailboxes only. ### Server-side signatures and PHI: what does the vendor touch? How a signature tool is deployed decides whether it ever sees email content, and that decides whether it belongs in your business associate inventory. | Deployment | What the vendor handles | Does email content pass through the vendor? | | --- | --- | --- | | Client-side add-in or API (Outlook add-in, Gmail signature settings) | Staff directory data and the signature HTML; the signature is inserted in the mail client | No. Scribe documents that with its Microsoft 365 cloud-based installation, emails don't go through Scribe's servers ([Scribe: Microsoft 365 client-side](https://help.scribe-mail.com/en/integrations/signatures/microsoft-365-client-side)) | | Server-side relay (mail flow rule to a smart host) | Every routed outbound message: headers, body and attachments | Yes. Scribe's documentation says the relay inserts the signature and passes recipients, subject, attachments and body through unchanged ([Scribe: Microsoft 365 server-side](https://help.scribe-mail.com/en/integrations/signatures/microsoft-365-server-side)) | | Native mail flow rule or footer (Exchange Online, Google Workspace) | Nothing outside your email platform | No; it stays within the platform you already have a BAA for, if you have one | With server-side routing, outbound email that contains PHI is received and transmitted by the signature vendor on your behalf. Don't assume the "conduit" exception covers it. HHS describes that exception as limited to transmission-only services, and says a cloud service provider that creates, receives or maintains ePHI is a business associate even if it can't view the data because it's encrypted ([HHS: HIPAA and cloud computing](https://www.hhs.gov/hipaa/for-professionals/special-topics/health-information-technology/cloud-computing/index.html)). A relay that rewrites the message body and re-signs it is doing more than carrying it. Whether a particular signature relay is a business associate is a determination for your privacy officer and counsel, but the conservative default is to treat it as one. #### Where Scribe stands, from its published documentation - Scribe publishes no business associate agreement. Its Trust Center lists SOC 2 Type II and GDPR as its frameworks and offers a GDPR data processing agreement ([Scribe Trust Center](https://security.scribe-mail.com)); it doesn't list HIPAA. - Scribe's help center states that "Scribe does not collect or process personal health information (PHI)" ([Scribe: data collected overview](https://help.scribe-mail.com/en/security/data-collected-overview)). That statement describes Scribe's intended data; it doesn't by itself settle the status of a relay that PHI-bearing email passes through. - Scribe's server-side documentation says it "cannot read or edit your emails", that the connection to Scribe is TLS-enforced in both directions, and that the return connector accepts mail only from two fixed Scribe IP addresses ([Scribe: Microsoft 365 server-side](https://help.scribe-mail.com/en/integrations/signatures/microsoft-365-server-side)). It doesn't document how long, if at all, message content is held on the relay. **Confirm BAA availability with Scribe before enabling server-side routing for any mailbox that may send PHI.** Ask, in writing: will Scribe sign a BAA, for which deployment types, whether message content is stored on the relay and for how long, where the relay is hosted, and which subprocessors handle routed mail. If the answer is no, or until it's yes, use client-side deployment only for those mailboxes. The same questions apply to any signature vendor with a server-side option. For the architecture itself, see [client-side vs server-side signatures](https://www.scribe-mail.com/en-US/handbook/client-side-vs-server-side-email-signatures). ### Should signature tracking be on for email to patients? Most signature tools count views and clicks. Scribe documents that tracking of signature openings and clicks starts when signatures are installed, that it records an anonymized IP address, the country derived from it, the email client and version, and the device type, and that it can be switched off in workspace settings ([Scribe: how Scribe tracks and stores data](https://help.scribe-mail.com/en/security/how-does-scribe-track-and-store-data)). The setting is workspace-wide in the documentation; per-signature or per-recipient opt-outs aren't described. HHS's bulletin on online tracking technologies addresses websites and mobile apps, not email, and part of it was vacated by a federal court in June 2024 as it applied to unauthenticated public webpages ([HHS: online tracking technologies](https://www.hhs.gov/hipaa/for-professionals/privacy/guidance/hipaa-online-tracking/index.html)). Its central concern still carries over by analogy: data such as IP address, device and timing, collected in the context of a patient's relationship with a provider, may be individually identifiable health information. Signature views on clinician-to-patient email reveal who opened mail from which practice and when. Practical options, from most to least conservative: 1. Turn signature tracking off for the workspace that serves clinical and patient-facing staff. 2. Run patient-facing staff in a separate workspace with tracking off, and keep tracking for corporate, recruiting or B2B teams in another. Scribe's paid plans allow multiple workspaces ([Scribe: Plans](https://help.scribe-mail.com/en/plans)); confirm with Scribe that your directory and mail integration can be split this way before you plan on it. 3. Keep tracking on only where your privacy officer has documented why it's acceptable, and avoid personalized tracking links on patient-facing templates. ### Patient-facing vs internal and partner signatures Most healthcare organizations need at least three signature types: | Audience | Include | Avoid | | --- | --- | --- | | Patients | Name, credentials, role, location, a general phone number, portal link without identifiers, a short notice asking mistaken recipients to delete the message, a line that email isn't for emergencies | Direct mobile numbers, condition-specific or sponsored banners, tracking links, long legal text | | Payers, vendors and business associates | Name, role, department, direct line, entity name, confidentiality notice | Marketing banners | | Internal | Name, role, department, extension, pager or on-call information if your workflow uses it | The external legal block, which only lengthens threads | Scribe's internal variant applies when every recipient is on the sender's domain; it works in Outlook and with server-side routing, but not with the client-side Gmail install, where one signature serves all mail ([Scribe: signature variants](https://help.scribe-mail.com/en/signature-variants)). Groups that use several domains (a hospital domain and a medical group domain, for example) should check whether "internal" in their tool means same domain or same organization. Patient-facing signatures should be assigned by role rather than by hand. Assign them to the clinical departments or groups synced from your directory, and set the auto-assign option so new hires pick up the right template on day one ([Scribe: assign teammates](https://help.scribe-mail.com/en/assign-teammates-to-a-signature)). ### Mobile devices and coverage gaps Clinicians send a large share of their email from phones. Client-side signature tools can't reach every mobile app: Scribe documents that its client-side installation works in the Gmail iOS app and the Outlook apps for iOS and Android, but not in the Gmail Android app or Apple Mail ([Scribe: mobile](https://help.scribe-mail.com/en/do-scribe-email-signatures-work-on-mobile)). Server-side routing closes the gap but raises the BAA question above. If you're client-side only, close the gap another way: - Require the Outlook mobile app for corporate mail through your mobile device management policy, so mobile mail goes through a supported client. - Add the essential notice with a native rule: Exchange Online's "Apply disclaimers" mail flow rule ([Microsoft Learn](https://learn.microsoft.com/en-us/exchange/security-and-compliance/mail-flow-rules/disclaimers-signatures-footers-or-headers)) or Google Workspace's footer setting ([Google Workspace Admin Help](https://knowledge.workspace.google.com/admin/gmail/advanced/add-a-standard-footer-to-outgoing-emails)). These run inside the platform, so no additional vendor sees the mail. Add an exception so messages that already carry the signature don't get a second notice. More detail in [mobile email signatures](https://www.scribe-mail.com/en-US/handbook/mobile-email-signatures). ### How do you roll out signatures across clinics and locations? 1. **Inventory mail paths.** List every way email leaves the organization: Outlook and Gmail clients, mobile, the EHR's patient messaging, the patient portal's notifications, CRM and marketing platforms. Signature tools only cover the first two or three; the rest have their own footer settings. 2. **Decide the deployment per population.** Client-side for anyone who may send PHI unless a BAA is in place for the server-side relay; server-side only where it's approved. 3. **Clean the directory.** Location, department, credentials and phone numbers come from Entra ID, Google Workspace or your HRIS. In Scribe a block whose field is empty is omitted from the signature, so missing credentials don't print as a blank label ([Scribe: Smart Fields](https://help.scribe-mail.com/en/smart-fields)). See [Entra ID attributes](https://www.scribe-mail.com/en-US/handbook/entra-id-email-signatures). 4. **Build templates per audience and location.** One patient-facing template can cover many clinics if the location block comes from the directory. 5. **Have the privacy officer approve** the notice wording, the tracking decision and the banner rules, and record the decision. 6. **Pilot one clinic,** check mail from desktop and each mobile app, then roll out by department. See the [rollout playbook](https://www.scribe-mail.com/en-US/handbook/email-signature-rollout-playbook). 7. **Audit monthly:** coverage, failed installs, missing data and template versions; see the [email signature policy guide](https://www.scribe-mail.com/en-US/handbook/email-signature-policy). For the platform setup itself, see the [Microsoft 365](https://www.scribe-mail.com/en-US/handbook/microsoft-365-email-signatures) and [Google Workspace](https://www.scribe-mail.com/en-US/handbook/google-workspace-email-signatures) guides. ### Questions to ask any signature vendor before a healthcare deployment - Will you sign a BAA, and does it cover server-side routing, client-side deployment, or both? - Does message content pass through your systems in each deployment type? Is any of it stored, logged or queued, and for how long? - Where are the relay and the signature service hosted, and which subprocessors touch routed mail? - Is transport encryption enforced, and how is the return path restricted? - Can view and click tracking be disabled per workspace, per signature or per audience? - What directory fields do you import, and can we limit them? - What audit trail exists for template and setting changes? - What independent assurance do you have (for example SOC 2 Type II), and will you share the report under NDA? ### Frequently asked questions #### Does HIPAA require an email signature or disclaimer? No. HIPAA requires safeguards for protected health information, such as transmission security for ePHI, and HHS allows email with patients when reasonable safeguards are applied. A disclaimer is a notice, not a safeguard. Templates are in our [HIPAA email disclaimer guide](https://www.scribe-mail.com/en-US/blog/10-essential-email-disclaimers-for-hipaa-compliance). This is general information, not legal advice. #### Is a staff email signature PHI? Generally not. A staff member's name, credentials, role, location and work phone describe the workforce, and the HIPAA definition of PHI excludes employment records a covered entity holds as an employer. PHI enters signatures through personalized patient links, condition-specific banners or pasted content. #### Do I need a BAA with my email signature vendor? If outbound email that may contain PHI is routed through the vendor (server-side signatures), treat the vendor as a likely business associate and get a BAA before enabling it; HHS describes the conduit exception as limited to transmission-only services. Client-side deployments that never receive email content raise a different, smaller question. Confirm with your privacy officer. #### Does Scribe sign a BAA? Scribe doesn't publish a BAA, and its Trust Center lists SOC 2 Type II and GDPR rather than HIPAA. Confirm BAA availability with Scribe directly before routing PHI-bearing mail through its server-side relay. Its documentation says client-side Microsoft 365 installation doesn't route email through Scribe's servers. #### Should email signature tracking be used on patient email? Be cautious. View and click tracking records data such as IP-derived location, device and timing for each recipient. On clinician-to-patient email, many organizations switch it off or keep it to non-clinical teams. Scribe documents a workspace-level setting to opt out of tracking. #### Can healthcare marketing banners go in email signatures? Banners about your own services are generally treated differently under HIPAA from third-party or sponsored promotions, which can fall within the Privacy Rule's definition of marketing. Keep condition-specific and sponsored banners off patient-facing signatures and have the privacy officer approve banner rules. #### How do I cover signatures on clinicians' phones? Client-side tools don't reach every app: Scribe's client-side install works in Gmail for iOS and the Outlook apps, but not Gmail for Android or Apple Mail. Either require the Outlook mobile app, add a native Exchange or Google Workspace footer for the essential notice, or use server-side routing once a BAA question is resolved. ### Related Handbook guides - [Email disclaimers: legal requirements by country and industry](https://www.scribe-mail.com/en-US/handbook/email-disclaimers) - [Client-side vs server-side email signatures](https://www.scribe-mail.com/en-US/handbook/client-side-vs-server-side-email-signatures) - [Mobile email signatures](https://www.scribe-mail.com/en-US/handbook/mobile-email-signatures) - [Email signature policy template](https://www.scribe-mail.com/en-US/handbook/email-signature-policy) - [GDPR and email signatures](https://www.scribe-mail.com/en-US/handbook/gdpr-email-signatures) ### Google Workspace Email Signatures: How to Deploy One Signature for All Users (2026 IT Guide) Source: https://www.scribe-mail.com/en-US/handbook/google-workspace-email-signatures Topic: Rollout Published: 2026-10-24 How IT admins roll out one managed signature to every Google Workspace user: what the Admin console and Gmail API can and can't do, directory sync with OUs and groups, server-side routing for Android and Apple Mail, and fixes for the common errors. > **TL;DR:** Google Workspace can't natively push one designed, personalized signature to every user. The Admin console only offers an "Append footer" compliance setting (the same text for everyone, invisible while composing), and the Gmail API can write signatures per user if you build the tooling. To roll out company signatures at scale, install a Marketplace signature app as a super admin, sync users, OUs and groups from the Google directory, and add server-side routing if you need Gmail on Android, Apple Mail and other clients covered. *Last reviewed: October 2026. Covers Gmail on the web, Gmail for iOS and Android, Apple Mail and other IMAP clients on Google Workspace accounts.* This guide is for Google Workspace admins who need every employee to send the same, correct signature: right title, right phone number, right legal text, on every device. It explains what Google gives you natively, where those tools stop, and how to deploy and verify a managed rollout step by step. If you only need to add a signature to your own Gmail account, see [how to add a signature in Gmail](https://www.scribe-mail.com/en-US/blog/how-to-add-signature-on-gmail-a-step-by-step-guide). ### Can Google Workspace set one signature for all users? Partly. Google's own admin documentation lists three routes for setting up user signatures: a default footer added in the Admin console, the Gmail API, and third-party apps from the Google Workspace Marketplace ([Set up Google Workspace user signatures in Gmail](https://knowledge.workspace.google.com/admin/gmail/set-up-google-workspace-user-signatures-in-gmail)). | Option | How it works | Seen while composing | Users can change it | Personalized per user | | --- | --- | --- | --- | --- | | Append footer (Admin console) | Gmail adds the same footer text to outgoing mail for an organizational unit | No | No | No | | Gmail API | Your script writes each user's signature into their Gmail settings | Yes | Yes | Yes, if you build it | | Marketplace signature app | A vendor app, installed by an admin, writes and maintains signatures from directory data | Yes | Overwritten by the app on update | Yes | | Server-side routing | Gmail routes outbound mail through a signature relay that inserts the signature in transit | No | No | Yes | #### The Append footer setting Append footer lives under **Admin console > Apps > Google Workspace > Gmail > Compliance** and needs the Gmail Settings administrator privilege. Per Google ([Add a standard footer to outgoing emails](https://knowledge.workspace.google.com/admin/gmail/advanced/add-a-standard-footer-to-outgoing-emails)): - It applies to an organizational unit; child OUs inherit it. - Footer text can be up to 10,000 characters. The editor doesn't accept raw HTML, and images must be hosted on a public web server (not Google Drive). - By default it applies to messages leaving the organization; a checkbox extends it to internal mail. - Plain-text messages get a plain-text version of the footer. - It isn't supported for messages encrypted with Google Workspace client-side encryption. - Changes can take up to 24 hours. It is the right tool for a single legal disclaimer. It is not a signature system: there are no per-user fields, no visual editor, and the sender never sees it. Disclaimer wording by country is covered in the [email disclaimers guide](https://www.scribe-mail.com/en-US/handbook/email-disclaimers). #### The Gmail API Gmail stores a signature on each "send-as" address. The `users.settings.sendAs` resource lets you read and update that signature for the primary address and for aliases ([Managing aliases and signatures, Google for Developers](https://developers.google.com/workspace/gmail/api/guides/alias_and_signature_settings)). Doing this for a whole domain means a service account with domain-wide delegation, a template engine, a scheduler, and error handling for every user the API rejects. Google notes that signatures set this way remain editable by users ([Google](https://knowledge.workspace.google.com/admin/gmail/set-up-google-workspace-user-signatures-in-gmail)), so you also need to re-apply them on a schedule. That custom build is what Marketplace signature apps package for you. Scribe's Gmail app, for example, requests exactly two Gmail scopes: `gmail.settings.basic` to set signatures on primary addresses and `gmail.settings.sharing` for aliases. Neither scope can read mail ([Scribe: data collected from Gmail](https://help.scribe-mail.com/en/security/data-collection/google-workspace-gmail)). #### Limits that apply to every method - **10,000 characters.** Gmail signatures are limited to 10,000 characters ([Gmail Help](https://support.google.com/mail/answer/8395)). Heavy inline HTML, long legal text and base64 images hit this quickly. When it happens, Gmail rejects the signature; our ["signature too long" fix](https://www.scribe-mail.com/en-US/blog/fix-your-gmail-signature-is-too-long-error-in-4-simple-steps) walks through the usual causes. - **One signature per send-as address in settings.** Users can keep several signatures, but what an admin tool writes is tied to an address. - **Mobile apps.** The Gmail apps have their own signature behavior, covered below. ### What do you need before you start? | Item | Why it matters | | --- | --- | | Super admin account | Scribe's Gmail app and directory sync both require a super admin ([Scribe docs](https://help.scribe-mail.com/en/integrations/signatures/google-workspace-client-side)). If you aren't one, Scribe lets you invite one into the workspace to finish the connection. | | Third-party app access policy | If your organization restricts API access, the connection fails with `Error 400: admin_policy_enforced` until the app is allowed under API controls ([Google: control which apps access Google Workspace data](https://knowledge.workspace.google.com/admin/apps/control-which-apps-access-google-workspace-data)) | | Clean directory data | Job title, department, phones and addresses in user profiles become signature content | | Custom attributes, if needed | Licence numbers, pronouns or booking links can live in custom user attributes ([Google: custom attributes](https://knowledge.workspace.google.com/admin/users/create-custom-attributes-for-user-profiles)) | | Aliases set up as "Send mail as" | Aliases created only in the Admin console can't receive a signature until Gmail knows them as send-as addresses (see troubleshooting) | | A pilot OU or group | Lets you turn the app on for a subset first | | DNS access (server-side only) | Routing through a relay requires a DKIM record for the relay | ### How do you install a signature app for the whole domain? With Scribe, the client-side installation is a Google Workspace Marketplace app. Steps from Scribe's documentation ([Scribe: Google Workspace](https://help.scribe-mail.com/en/integrations/signatures/google-workspace-client-side)): 1. In Scribe, open the Google Workspace integration and click **Install Scribe App**. This opens the Marketplace listing. 2. Click **Install**, then **Continue** in the "Admin install" dialog. 3. Select **Everyone at your organization** and agree to the terms of service. To pilot first, you can later restrict the app to specific OUs or groups (see phased rollout). 4. Click **Done** and return to Scribe. 5. Confirm with **Yes I installed it**. Scribe says Google's validation usually takes a few seconds. 6. Click **Install signature** and deploy all signatures at once or one at a time ([Install signatures](https://help.scribe-mail.com/en/install-signatures)). Scribe's status documentation notes that Gmail installs can take up to 72 hours to show as Installed ([Statuses and errors](https://help.scribe-mail.com/en/signature-installation-statuses-and-errors)). Teammates don't need to do anything; after the first install, design changes you publish are pushed automatically. One design decision to make now: **Gmail's client-side install writes a single signature into Gmail settings, with no separate reply or internal variant** ([Scribe: signature variants](https://help.scribe-mail.com/en/signature-variants)). If you want a shorter signature on replies or a minimal one for internal mail, you need server-side routing, which applies variants per message. ### How do you sync users, OUs and groups from the Google directory? Directory sync is a separate connection from the Gmail app. It imports people and keeps their data current. 1. In Scribe, go to **Teammates > + Add Teammates > Google Workspace**, or **Integrations > Teammates**. 2. Click **Connect Google Workspace** (or **Invite a Super Admin**) and sign in. 3. Accept the read-only directory scopes. 4. Select who to sync: individual teammates, whole organizational units, or Google Groups (which you can expand before syncing). 5. Turn on **Auto-sync new teammates added to Google Workspace** and, if needed, **Import email aliases**. 6. Click **Sync teammates**. Sync runs once a day based on your time zone, plus on demand with **Refresh**. Data flows one way, from Google to Scribe, so fixes are made in Google ([Scribe: Google Workspace directory](https://help.scribe-mail.com/en/editor/google-workspace-directory)). | Directory API scope | Purpose | | --- | --- | | `admin.directory.user.readonly` | Read users | | `admin.directory.orgunit.readonly` | Read organizational units | | `admin.directory.group.readonly` | Read groups | | `admin.directory.domain.readonly` | Read domains | | `admin.directory.userschema.readonly` | Read custom attributes for use in signatures | Scribe lists the stored fields as profile picture, first name, surname, job position, mobile, home and work phones, home, work and other addresses, organizational unit, custom attribute values, group and OU memberships, and domains ([Scribe: scopes used from Google Workspace](https://help.scribe-mail.com/en/security/scopes-used-from-google-workspace)). Assignment works best as a rule: assign a signature to an OU or group, or by Smart Field condition such as "Department is Sales," and tick auto-assign for future teammates so new hires get the right signature on day one ([Assign teammates](https://help.scribe-mail.com/en/assign-teammates-to-a-signature)). Empty fields are dropped from the rendered signature rather than shown as blank lines ([Smart Fields](https://help.scribe-mail.com/en/smart-fields)). ### How do you add server-side routing for Android, Apple Mail and other senders? Client-side coverage on Google Workspace has gaps. Scribe's mobile matrix: the Gmail app for iOS is covered; the Gmail app for Android and Apple Mail are not, because those apps don't let external tools set the compose signature ([Scribe: mobile](https://help.scribe-mail.com/en/do-scribe-email-signatures-work-on-mobile)). Server-side routing, which Scribe offers on the Business and Enterprise plans, closes the gap by inserting the signature after the message leaves the device. The Google side uses three standard Gmail admin features: a mail host (route), the SMTP relay service, and a content compliance rule ([Google: content compliance](https://knowledge.workspace.google.com/admin/gmail/advanced/set-up-rules-for-advanced-email-content-filtering); [Google: SMTP relay service](https://knowledge.workspace.google.com/admin/gmail/advanced/route-outgoing-smtp-relay-messages-through-google)). With Scribe ([Scribe: Google Workspace server side](https://help.scribe-mail.com/en/integrations/signatures/google-workspace-server-side)): 1. **Add a host.** In **Apps > Google Workspace > Gmail > Hosts**, add a route named `Scribe`: single host `smtp.server.scribe-mail.com`, port 25. 2. **Configure the SMTP relay service.** In **Gmail > Routing**, configure **SMTP relay service** with description `Receive from Scribe`, "Only accept mail from the specified IP addresses" set to `15.236.243.144` and `51.44.50.107`, and **Require TLS encryption**. 3. **Create the content compliance rule.** In **Gmail > Compliance > Content compliance**, add `Route to Scribe` for **Outbound** and **Internal - sending** messages, matching if ALL of: Full headers **do not contain** `X-Scribe-Processed` (prevents double processing). 4. Envelope sender **does not match regex** `.*@google\.com$` (excludes Google system mail such as Forms receipts, which Google's relay rejects if routed). 5. **Configure DKIM** in Scribe and publish the `scribe._domainkey` record for each sending domain. Scribe re-signs processed mail and adds an ARC chain, because inserting a signature invalidates Google's original DKIM signature. 6. **Install signatures** and send a test message to an external mailbox. Check for the `X-Scribe-Processed` header. Rolling back means disabling the content compliance rule; the host and relay entries can stay unused. When both client-side and server-side are connected, Scribe uses client-side where it's supported so people see their signature while composing, and server-side covers the rest ([Integrations overview](https://help.scribe-mail.com/en/integrations-overview)). ### What is covered on mobile and third-party senders? | Sending from | Client-side (Gmail app) | Server-side routing | | --- | --- | --- | | Gmail on the web | Yes, visible while composing | Yes | | Gmail for iOS | Yes; Scribe notes the signature is applied after sending, and the app's own "Mobile Signature" must be off ([Scribe docs](https://help.scribe-mail.com/en/troubleshooting/gmail-ios-app-signature-not-showing-up)) | Yes | | Gmail for Android | No | Yes | | Apple Mail (Mac, iPhone) | No (a manual Apple Mail integration exists per user) | Yes | | Outlook or other clients on a Google account | Depends on the client | Yes | | CRM or sequencer sending through the user's Gmail (for example HubSpot one-to-one and sequence emails) | No | Yes, if the From address is a teammate with an installed signature ([Scribe docs](https://help.scribe-mail.com/en/integrations/signatures/hubspot-server-side)) | | Tools that send from their own servers (for example HubSpot marketing email) | No | No; the mail never passes through Google | | Reply and internal variants | No (single signature in Gmail settings) | Yes | ### How do send-as aliases and shared addresses work? Each person can have one signature on their primary address and separate signatures on any number of aliases; Scribe bills per primary address, so aliases don't add cost ([Scribe: aliases](https://help.scribe-mail.com/en/how-do-scribe-email-signatures-work-with-email-aliases)). Aliases are imported from the directory when **Import email aliases** is on, and the right signature appears based on the From address the user selects. The catch is Gmail itself: an alias that exists only in the Admin console can receive mail, but Gmail won't accept a signature for it until the user has added it under **Settings > Accounts > Send mail as**. Until then, the API returns "User not found" ([Scribe docs](https://help.scribe-mail.com/en/troubleshooting/fix-user-not-found-error-for-email-aliases)). Build that step into your alias provisioning. Scribe doesn't import shared mailboxes from Google Workspace. For an address a team sends from, such as support@ or sales@, add it as an alias on each person who sends from it, and make sure each of them has it as a Send mail as address in Gmail ([Scribe: aliases](https://help.scribe-mail.com/en/how-do-scribe-email-signatures-work-with-email-aliases)). ### How do you phase the rollout with OUs? Google Workspace lets you turn a Marketplace app on or off per organizational unit or group under **Apps > Google Workspace Marketplace apps > Apps list > [app] > User access**. Scribe uses the same setting: if the app is off for a user's OU, their install fails with "Google Workspace API has forbidden access to this teammate's signature" ([Scribe docs](https://help.scribe-mail.com/en/troubleshooting/google-workspace-forbidden-access)). That makes OUs a clean rollout lever. 1. **Week 0.** Fix directory data; create custom attributes you need; approve templates. 2. **Week 1: pilot.** Turn the app on for a pilot OU or group of 10 to 30 people on mixed devices. If you test server-side, limit the content compliance rule to the pilot OU. 3. **Week 2: first departments.** Turn the app on for the teams that email customers most and assign their signatures by department condition. Use the install modal's option to email teammates a preview of their new signature. 4. **Week 3: everyone.** Set the app to **On for everyone**, enable auto-assign, and apply the compliance rule at the top-level OU if you use server-side. 5. **Steady state.** Marketing owns templates and campaign banners; IT owns the app, the directory connection and the routing rule. Scribe estimates around 10 minutes of IT work and 15 to 20 minutes of Marketing work for the setup itself; most elapsed time is internal sign-off ([Scribe docs](https://help.scribe-mail.com/en/how-long-does-it-take-to-set-up-scribe)). ### How do you fix the common errors? | Error or symptom | Cause | Fix | | --- | --- | --- | | `Error 400: admin_policy_enforced` | API controls block the app | Allow the app under API controls ([Scribe](https://help.scribe-mail.com/en/troubleshooting/admin-policy-enforced), [Google](https://knowledge.workspace.google.com/admin/apps/control-which-apps-access-google-workspace-data)) | | App not validated after 30 minutes | Wrong Google account or domain; not installed for everyone; not a super admin; a personal Gmail account | Re-check the account and "Everyone at your organization" ([Scribe](https://help.scribe-mail.com/en/troubleshooting/google-add-in-not-validating)) | | Integration shows Access lost | Scopes no longer granted | Admin console > Apps > Google Workspace Marketplace apps > Scribe > **Grant access** ([Scribe](https://help.scribe-mail.com/en/troubleshooting/google-workspace-access-lost)) | | "Forbidden access to this teammate's signature" | App turned off for that OU or group | Set App distribution to On for the OU, then reinstall | | "User not found on Google Workspace" on an alias | Alias not added as Send mail as | Add it in Gmail settings, then push again | | "Signature is too long" | Over Gmail's 10,000-character limit | Remove elements or use hosted images, then reinstall | | Signature missing in Gmail web | Signature defaults not set to "my signature," or Plain text mode on | Fix both settings ([Scribe](https://help.scribe-mail.com/en/troubleshooting/is-your-gmail-settings-correctly-set-up)) | | Signature missing on Gmail iOS | Local mobile signature enabled | Turn off "Mobile Signature" in the app | | Status stays Not installed | Gmail disabled for the user, or account inactive | Enable Gmail for the user in Google Workspace | | Google Forms receipts bounce after enabling routing | System mail routed to the relay | Keep the `.*@google\.com$` envelope-sender exclusion | ### What does the security review need to know? - **Client-side:** Gmail settings scopes only; mail is not routed anywhere and the scopes cannot read mail. - **Directory:** read-only Admin SDK scopes listed above; nothing is written back to Google. - **Server-side:** outbound and internal-sending mail takes one TLS hop to Scribe and returns through the SMTP relay from two fixed IPs. Scribe documents that recipients, subject, attachments and body text pass through unchanged, and that it adds its own headers, a fresh DKIM signature and an ARC chain. SPF is unaffected because Google still makes the final delivery. - **Assurance:** Scribe states it is SOC 2 Type II and GDPR compliant and publishes a [Trust Center](https://security.scribe-mail.com) ([Scribe security](https://help.scribe-mail.com/en/what-scribe-does-concerning-security)). ### Where does Scribe fit in Google Workspace? Scribe covers the three building blocks in this guide from one dashboard: the [Gmail app](https://www.scribe-mail.com/en-US/integrations/google-workspace-gmail), [directory sync](https://www.scribe-mail.com/en-US/integrations/google-workspace-directory) with custom attributes, and [server-side routing](https://www.scribe-mail.com/en-US/integrations/google-workspace-server-side). HR data can come from tools such as BambooHR, Workday, Rippling or HiBob when the directory isn't the system of record. Admins can also audit and update signatures from Claude or ChatGPT through Scribe's [MCP server](https://www.scribe-mail.com/en-US/mcp), or from scripts through the [API](https://www.scribe-mail.com/en-US/api), for example to check per-email install state during onboarding. Plans are per user, with a free plan for two users and a 14-day trial ([pricing](https://www.scribe-mail.com/en-US/pricing)). ### Frequently asked questions #### Can a Google Workspace admin set everyone's Gmail signature? Not with a built-in signature editor. The Admin console's Append footer setting adds the same footer to outgoing mail for an organizational unit, but users don't see it and it can't be personalized. To write a personalized signature into each user's Gmail settings, use the Gmail API or a Marketplace signature app installed by a super admin. #### What is the Gmail signature character limit? 10,000 characters, according to Gmail Help. Google's Append footer is also limited to 10,000 characters. Inline images and long legal text are the usual reasons a signature exceeds it. #### Can users change a signature set by the admin? Signatures written to Gmail settings through the API stay editable by the user, according to Google, so tools re-apply the approved version. The Append footer can't be changed or removed by users. #### Do managed Gmail signatures work on Android? Not client-side: the Gmail app for Android doesn't let signature tools set the compose signature. Scribe supports Gmail for Android only with server-side installation (Business and Enterprise plans), which also covers Apple Mail and other clients because the signature is added after the message is sent. #### Can I give replies or internal emails a different signature in Gmail? Not with a signature stored in Gmail settings, which holds one signature per address. Scribe's client-side Gmail install writes a single signature with no reply or internal variants; its server-side routing chooses the primary, on-reply or internal variant for each message. #### Why do I get "User not found" when installing a signature on an alias? The alias exists in the Admin console but hasn't been added as a Send mail as address in the user's Gmail settings. Add it under Settings, Accounts, Send mail as, then push the signature again. #### How do I roll out to one department first? Turn the signature app on only for a pilot organizational unit or group under Apps, Google Workspace Marketplace apps, then User access. Expand to more OUs, then set it On for everyone. Scribe shows a forbidden-access error for users whose OU doesn't have the app. #### Does a Gmail signature app read my email? It shouldn't need to. Scribe's Gmail app requests only gmail.settings.basic and gmail.settings.sharing, which manage signatures and can't read messages; directory sync uses read-only Admin SDK scopes. ### Related Handbook guides - [Client-side vs server-side email signatures](https://www.scribe-mail.com/en-US/handbook/client-side-vs-server-side-email-signatures) - [Microsoft 365 and Exchange Online company-wide signatures](https://www.scribe-mail.com/en-US/handbook/microsoft-365-email-signatures) - [Email disclaimers by country and industry](https://www.scribe-mail.com/en-US/handbook/email-disclaimers) - [Company email signature policy and templates](https://www.scribe-mail.com/en-US/blog/best-practices-for-company-wide-email-signature-management) ### Gmail "Signature Is Too Long" Error: Why It Happens and How IT Fixes It for Everyone (2026) Source: https://www.scribe-mail.com/en-US/handbook/gmail-signature-too-long Topic: Rendering Published: 2026-10-24 What Gmail's 10,000-character signature limit counts, why signatures from generators, Word and HubSpot hit it, how to measure and shrink a signature, and how IT fixes the error for the whole company with centrally deployed signatures. > **TL;DR:** Gmail accepts signatures of up to 10,000 characters, and that count covers the signature's underlying HTML, not just the text you see. Google also says images count toward the limit. Signatures built in generators or pasted from Word, web pages and design tools hit it because they carry inline CSS on every element, nested tables, long tracking links and sometimes images embedded as data. The fix is to host images and link them, strip repeated styles and wrappers, shorten links and move long legal text out of the signature. Company-wide, deploy signatures centrally so the HTML is generated lean once and a size problem shows up as an install error for IT, not as a pasted signature that silently fails for one user. *Last reviewed: October 2026.* Gmail's "signature is too long" error is one of the most common Gmail signature problems, and it tends to land on IT just when a new company template is being rolled out. This guide explains what Gmail is counting, why signatures that look small fail, how to measure and shrink a signature, and how to fix the problem for the whole company rather than one mailbox at a time. If you only need to add a signature to your own Gmail account, Scribe's step-by-step posts on [adding an HTML signature to Gmail](https://www.scribe-mail.com/en-US/blog/how-to-add-a-html-signature-to-gmail-step-by-step-guide) and [adding an image](https://www.scribe-mail.com/en-US/blog/how-to-add-image-in-gmail-signature-step-by-step-guide-for-marketers) cover that. ### What does Gmail's 10,000-character limit count? Google's help states: "You can put up to 10,000 characters in your signature." It adds that images count toward that limit and that if you get an error you should resize the image ([Gmail Help: create a signature](https://support.google.com/mail/answer/8395)). Three points follow from how Gmail stores signatures: - **Markup counts.** The signature is stored as HTML. Every tag, attribute, inline `style`, link URL and image address uses characters, even though none of it is visible. A signature with 300 visible characters can easily carry several thousand characters of markup. - **Embedded images count heavily.** An image pasted into the editor can end up embedded as encoded data rather than referenced by URL, and encoded image data runs to thousands of characters for even a small logo. That's why Google's advice for the error is to resize the image. - **The limit is per signature, per send-as address.** Gmail keeps a signature on each address a user can send from, and the Gmail API sets them the same way ([Google for Developers: alias and signature settings](https://developers.google.com/workspace/gmail/api/guides/alias_and_signature_settings)). Every signature on every alias has to fit. The limit also applies when signatures are set centrally. Scribe, which writes each teammate's signature into their Gmail settings, reports a failed installation with the message that "the signature is over Gmail's 10,000 character limit" when a template is too large ([Scribe: installation statuses and errors](https://help.scribe-mail.com/en/signature-installation-statuses-and-errors)). Central deployment doesn't bypass the limit; it surfaces it to the admin. ### Why do generator-made signatures hit the limit? Free signature generators, marketing tools and design apps optimize for looking right everywhere, not for size. The usual causes, roughly in order of how much they add: 1. **Images embedded instead of hosted.** A headshot or logo copied from a document or a desktop app is often pasted as image data. One embedded image can use more of the budget than the rest of the signature combined. 2. **Inline styles on every element.** Email HTML has to inline its CSS, and generators repeat the full font, color, size, line-height and margin declarations on every cell, span and link, often with fallbacks for several clients. 3. **Nested layout tables.** Two columns, a divider and a row of icons can produce tables nested three or four levels deep, each with its own attributes. 4. **Long links.** Tracking redirects, UTM parameters and signed image URLs can run to 200 or 300 characters each. A signature with eight social icons has sixteen URLs: one for each link and one for each icon image. 5. **Pasting from Word or a web page.** Copying a signature out of Word, a browser tab or another email client brings along class names, conditional comments and wrapper elements that Gmail keeps. 6. **Long legal text.** A disclaimer of a few hundred words, styled inline, is a large share of the budget on its own. HubSpot's free generator is a frequent example in the wild; its community forum has threads titled "Signature too long with Gmail - using Hubspot free signature tool" ([HubSpot Community](https://community.hubspot.com/t5/Email-Marketing-Tool/Signature-too-long-with-Gmail-using-Hubspot-free-signature-tool/td-p/185091)). The same causes apply to any generator. A note for HubSpot users: Scribe has no native HubSpot integration. Emails sent from HubSpot through a connected Gmail or Outlook inbox pick up the Scribe signature only with server-side routing, and HubSpot marketing emails, which HubSpot sends from its own servers, get no signature ([Scribe: HubSpot server side](https://help.scribe-mail.com/en/integrations/signatures/hubspot-server-side)). ### How do you measure a signature before pasting it? Measure the HTML, not the text. Gmail sanitizes and rewrites what you paste, so its count won't match your file exactly, but the raw size tells you how close you are. 1. Get the HTML. From a generator, use its "copy HTML" or "view source" option. From an existing Gmail signature, open the signature in a message you've sent, right-click and choose **Inspect**, then copy the outer HTML of the signature block. 2. Save it to a file and count characters, for example `wc -m signature.html` on macOS or Linux, or `(Get-Content signature.html -Raw).Length` in PowerShell. 3. Search the file for `data:image`. Any match is an embedded image and the first thing to remove. 4. Count the `style=` attributes and the `
