Exclaimer & CodeTwo alternative

A free Exclaimer alternative for teams that just need consistent signatures

Enterprise signature suites bill per mailbox every month and route your mail through their servers to do it. SignatoryGrid gives you the part most teams actually want — one branded template, rolled out to everyone — for free, with no connector and no admin consent.

When to pick which

Pick SignatoryGrid if…

  • You have 3–500 people and want one on-brand signature everywhere.
  • You don't want a per-mailbox subscription forever.
  • You'd rather not change mail routing or get a security review.
  • Your team is mixed: Gmail, Outlook, Apple Mail, Superhuman.

Pick a server-side suite if…

  • You must legally guarantee a disclaimer on every outbound mail.
  • You run signature ad campaigns with per-recipient targeting.
  • You need Exchange-level enforcement across thousands of mailboxes.
  • Compliance requires signatures applied outside the user's control.

Frequently asked

Is SignatoryGrid really a free Exclaimer alternative?

Yes. Exclaimer and CodeTwo bill per mailbox, per month. SignatoryGrid is completely free with unlimited signatures and unlimited teammates — there is no paid tier to upgrade to.

What does Exclaimer do that SignatoryGrid doesn't?

Exclaimer injects signatures server-side at the Microsoft 365 or Google Workspace transport layer, which enforces signatures on every device automatically. SignatoryGrid uses a paste-based workflow instead: each teammate claims a personal link and pastes their signature once. That means no tenant-wide admin consent, no mail routing changes, and no connector to maintain.

Do I need admin access to Microsoft 365 or Google Workspace?

No. Because nothing is injected into your mail flow, you don't need Global Admin, an Exchange connector, or a security review. Anyone on the team can set it up.

How do I migrate from Exclaimer or CodeTwo?

Rebuild your signature in the brand editor (it takes a few minutes), import your roster by CSV, and share the claim links. Then cancel your seats — nothing is locked to a mail server, so there is no cutover window.

Can I still update everyone's signature at once?

Yes. Change the brand, logo, colours, or disclaimer in the editor and every claim link renders the new version instantly. Teammates re-paste once after a rebrand.
