Animated email signatures that actually render.
Pick a design, add your details, and get a signature with an animated avatar and a hand-inked mark that works in Gmail, Outlook and Apple Mail, on desktop and on your phone. Everything runs in your browser.
Every design keeps frame 1 complete (classic Outlook shows only that frame), stays under 10,000 characters, and ships GIFs of 300 KB or less at 12 fps or less.

Sixteen designs, all real output
Every card below is generated by the same renderer and serializer the builder uses: table-based HTML with hosted GIFs, nothing mocked up.

Built for the inbox, not the browser
Email clients are hostile places. MailMotion works within their rules instead of hoping for the best.
It renders for real
Table layouts, inline styles, hosted GIFs and PNG icons. No SVG, no <style>, no data URIs that Gmail strips.
Private by default
No tracking pixels, no read receipts, no accounts. Photos are processed in your browser and metadata is stripped.
Open source
Self-host it with Docker, use the CLI in CI, or fork a design. The engine is MIT, the apps are AGPL.
Security built in
Everything is HTML-escaped, links are https-only, uploads are re-validated and the builder ships a strict CSP.
From idea to installed in a few minutes
Design
Pick a design, enter your name and photo, and tweak colours, fonts, socials and your signature mark.
Host the images
Gmail needs public image URLs. Run your own storage server in one command.
Install
Copy the signature into Gmail or Outlook, or use the Apple Mail file and the send-to-phone page.
Hosting the images
| Your storage | |
|---|---|
| For | Technical users and teams |
| How | docker compose up with disk, S3, R2 or MinIO |
| Image URL | https://img.yourdomain.com/<hash>.gif |
| Cost | Your own storage (often free) |
Prefer not to host anything yourself? Download a ZIP, host the files anywhere, and MailMotion regenerates the HTML with your base URL.
