The shortlist
Seven Exclaimer alternatives, and who each is for
We make Scribe, so it is listed first. Every tool, ours included, is described from its vendor's public pricing and product pages as of October 2026, with its main limitation.
Scribe
Best for: Teams of 50 to 5,000+ where Marketing runs signatures and IT sets them up once
Centralised signatures for Google Workspace and Microsoft 365, installed client-side so people see them while composing, with server-side as an option. Campaign banners, click and conversion analytics, and a full developer stack: REST API, webhooks, CLI and an MCP server for Claude and ChatGPT.
- Pricing
- Free for 2 users; $116/month for 50 users billed yearly; Enterprise quote from 100 users.
- Watch out for
- Costs more per user than the cheapest tools on this list, and does not support on-premises Exchange.
CodeTwo
Best for: Microsoft-only organisations that want a low per-user price and 24/7 support
A Microsoft 365 specialist with server-side cloud mode, an Outlook add-in, ISO/IEC 27001 certification, and a choice of Azure region for stored settings.
- Pricing
- $0.81 to $1.36 per user/month depending on volume, 10-licence minimum.
- Watch out for
- No Google Workspace support, no public API, and analytics rely on UTM tags in your own tools.
Letsignit
Best for: Mid-size and large companies on Microsoft 365 or Google Workspace that want campaigns and A/B tests
A French signature platform with add-in deployment, campaign scheduling and A/B testing, a click analytics dashboard and a Salesforce connector. It also sells a Slides product for presentations.
- Pricing
- $2 per user/month on an annual subscription.
- Watch out for
- Exchange, server-side (SMTP) deployment and on-premises AD are Enterprise-only; the public API covers signature retrieval.
WiseStamp
Best for: Small businesses and freelancers who start from a personal signature generator
The best-known signature generator, with company plans that add Google Workspace and Microsoft 365 integration, employee sync and, on higher tiers, banners, analytics and server-side deployment.
- Pricing
- From $19/month plus $1 per employee (Basic), billed annually.
- Watch out for
- Banners and analytics start on Grow, server-side on Platform ($189/month base); no public API.
Opensense
Best for: B2B revenue teams that want signature banners targeted by account and CRM stage
Signature management plus account-based banner targeting, A/B tests and CRM integrations, sold alongside a separate email tracking product.
- Pricing
- $1 to $5 per user/month, with a $500/month minimum plus a service plan.
- Watch out for
- The $500 monthly minimum makes it expensive below a few hundred users; targeting features need the upper plans.
Xink
Best for: Budget-conscious teams under 300 users that want directory-driven signatures
A Danish signature manager that syncs from Entra ID, Google Directory, on-premises AD or SQL, with scheduled campaigns, built-in statistics and a REST API.
- Pricing
- About $0.55 to $1.10 per user/month, volume-based, up to 300 users.
- Watch out for
- Above 300 licences pricing is by quote; server-side deployment is not documented.
Rocketseed
Best for: Companies that want a managed, done-for-you setup including banner design
A server-side signature and banner platform for Microsoft 365 and Google Workspace, sold with a one-time setup service and 24/7 support.
- Pricing
- About $1.02 to $1.18 per user/month billed yearly for 50 to 200 users, plus a setup fee.
- Watch out for
- Server-side only, so people do not see the signature while composing; setup fee not published.
How to switch
How to switch from Exclaimer to Scribe
Five steps. Run both tools side by side until the pilot group signs off, so nobody sends an email without a signature.
Connect your email platform and directory
Start a free trial, connect Google Workspace or Microsoft 365, and sync teammates from Entra ID, Google Directory, Okta or your HRIS. Names, titles and phone numbers fill in automatically.
Rebuild your Exclaimer template
Recreate your current signature in the no-code editor or start from a template, then map each Exclaimer field to a Scribe Smartfield. Add reply and internal variants if you used them.
Test with a pilot group
Publish to one team first and check rendering in Outlook, Gmail and on mobile. Choose client-side, server-side or both.
Turn off Exclaimer signatures
Once Scribe signatures are live for a group, remove those users from your Exclaimer signature rules. If you used Exclaimer server-side, remove its mail-flow connector and transport rule; if you used the Outlook add-in, unassign it in the Microsoft 365 admin centre. This avoids double signatures.
Roll out and move your campaigns
Publish to everyone, recreate active banner campaigns, and add the Scribe SDK to your website so signature clicks are tied to conversions from day one.
FAQ
Exclaimer alternatives: common questions
The most common Exclaimer alternatives are Scribe (Marketing-run signatures with conversion analytics, API and MCP), CodeTwo (Microsoft 365 only, low price), Letsignit (add-in deployment with A/B-tested campaigns), WiseStamp (small teams), Opensense (account-based banners, $500/month minimum), Xink (low-cost, directory-driven) and Rocketseed (managed server-side setup).
On published list prices, Xink (about $0.55 to $1.10 per user per month up to 300 users) and CodeTwo ($0.81 to $1.36, Microsoft 365 only) are the cheapest. Exclaimer itself starts at $0.90 per user per month on its Starter plan, billed annually, with campaigns on Standard ($1.45) and analytics on Pro ($1.75).
Scribe, Letsignit, WiseStamp, Opensense, Xink and Rocketseed all support Google Workspace. CodeTwo does not: it is built for Microsoft 365.
Scribe has a public REST API, webhooks, a CLI and a hosted MCP server for AI assistants such as Claude and ChatGPT. Xink documents a REST API, and Letsignit has a public API for retrieving signatures. Exclaimer does not publish a public developer API reference.
Not on list price. Scribe costs about $2.32 per user per month at 50 users billed yearly, against $0.90 to $1.75 for Exclaimer. Scribe includes campaigns, click analytics and conversion tracking without a plan upgrade, is free for up to 2 users, and has no 10-user minimum.
Connect the new tool to Microsoft 365 or Google Workspace, sync your directory, rebuild your templates, test on a pilot group, then remove those users from Exclaimer's signature rules (and its mail-flow connector or Outlook add-in) so nobody gets two signatures. With Scribe, most teams publish a first signature in under 30 minutes.
