Email signature software
Email signature software without the enterprise bloat.
Most signature tools charge per user, per month, forever. SignatoryGrid is a one-time purchase with a free tier for small teams.

Frequently asked
How is this different from Exclaimer or WiseStamp?
SignatoryGrid focuses on simple team rollout — no Exchange integration, no per-user subscription. Pay once for slots and use them forever.
Is there a free plan?
Yes, free for 3 users. Bigger teams buy a one-time slot pack.
Do I need to install a plugin?
No plugins, no browser extensions, no admin agents. Each teammate pastes their signature into their mail client.
Does it work with Google Workspace and Microsoft 365?
Yes — the signatures render cleanly in both, plus Apple Mail, Superhuman, and Outlook.com.
