Exclaimer alternative
A simpler Exclaimer alternative for Google Workspace
Exclaimer is a capable enterprise platform - built for large organizations with IT teams and annual contracts. If you're a Google Workspace team that wants professional signatures without the complexity or the mail routing, SignStampd is the faster path.
Why teams choose SignStampd over Exclaimer
No mail routing
SignStampd uses Google's Gmail API to set signatures directly. Your email never passes through our servers - it stays entirely within Google's infrastructure.
2-minute setup
No IT ticket. No mail server changes. One domain-wide delegation step in your Google Admin console and you're connected.
Built for Google Workspace
SignStampd is built exclusively for Google Workspace teams. Not a Microsoft 365 tool with Google support bolted on.
No seat minimum, no annual lock-in
Start with 2 users or 200. Cancel any time from your billing page. No 30-day cancellation notice required.

What teams run into with routing-based tools
Bloated HTML hits Gmail's limit
Server-side tools often generate nested tables with repeated inline styles. When a signature has to sync into Gmail (for example with S/MIME) rather than being added after send, that bulk can blow past Gmail's ~10,000-character limit and get cut off. SignStampd produces lean, Gmail-safe HTML built to stay under it.
Routing is a single point of failure
Appending signatures by routing every outgoing message through a vendor means changing MX or SPF records and trusting a third party with all of your mail. SignStampd never routes email - it writes the signature directly through the Gmail API, so delivery stays in Google.
No surprise tracking pixels
Some signature vendors quietly add a tracking pixel to every outbound email, which can alarm security-conscious recipients. SignStampd adds none - it only sets the signature field and touches nothing else in your mail.
How SignStampd works
Step 1
Connect your Workspace
One admin login, then authorize domain-wide delegation in Google Admin console. Takes about 2 minutes.
Step 2
Build your template
Logo, merge fields, accent color, font. Live preview shows exactly how signatures will look in Gmail.
Step 3
Push to everyone
Select users, click push. Signatures appear in Gmail compose within seconds. Employees don't do anything.

FAQ
Does SignStampd route email like Exclaimer does?+-
No. SignStampd uses the Gmail API to update each user's signature field directly. Your email never passes through our servers.
What's the minimum number of users?+-
No minimum. SignStampd works for a team of 2 or a team of 500.
Is there an annual contract?+-
No. Pay month to month, cancel any time from your billing page.
How long does setup take compared to Exclaimer?+-
Exclaimer's server-side routing typically requires IT involvement and a security review process. SignStampd's domain-wide delegation setup takes about 2 minutes in your Google Admin console.
Will my signatures hit Gmail's size limit?+-
Gmail caps a signature at about 10,000 characters, and heavily generated signatures full of nested tables and repeated inline styles can get cut off. SignStampd generates lean, table-based Gmail-safe HTML that stays well under that limit.
Does SignStampd add tracking pixels to our outgoing email?+-
No. SignStampd only sets the signature field; it never routes your mail or injects tracking pixels. Some signature vendors add a per-sender pixel to every outbound message - SignStampd does not, and your email stays entirely within Google.
