Comparison
Free Exclaimer alternative: mailimza
Exclaimer is a paid platform for managing signatures centrally across Microsoft 365, Google Workspace and Exchange, with a 10-user minimum. Smaller teams often look for a free alternative. mailimza needs no account and builds a signature and setup page for everyone on an Excel or CSV list.
mailimza fits better for small teams or one-off projects that want free signatures without an account or a central setup. As of October 2026, Exclaimer may fit better if you need server-side or client-side signatures applied automatically to every email, rules by department, banners and engagement analytics.

Yes. There is no sign-up and no limit on the number of people. mailimza does not host images, so for Gmail and Outlook on the web you enter image URLs from your own server.
