About
MySigMail builds open-source tools for professional email design.
Our projects
MySigMail Card is a production-grade visual email builder with reusable blocks, responsive previews, JSON import and export, and clean HTML output. Use it online for free or self-host it.
MySigMail is a free and open-source email signature generator for Gmail, Outlook, Apple Mail, and other email clients. It makes polished, brand-ready signatures accessible without a closed platform.
Both projects are released under AGPL-3.0. They provide independent, transparent alternatives to subscription-only email tools.
What contributions fund
Contributions support ongoing development across both projects:
- email-client compatibility and export quality;
- new production-ready blocks, templates, and signature layouts;
- accessibility, documentation, testing, and infrastructure;
- long-term maintenance of Card's free hosted app and both open-source codebases.
