MySigMail v2 — Open-Source Email Signature Generator

#vue #opensource #webdev

In 2019, I launched MySigMail, a simple tool to create professional email signatures. It got some traction, but I got swept up in other open-source projects—like my code snippet manager massCode, which has grown a vibrant community. Now, I’m excited to revive app with MySigMail v2, an open-source, client-side email signature generator designed for developers who value transparency and control.

Why MySigMail?

Let’s face it: creating a professional email signature from scratch is not trivial. You’re stuck wrestling with:

  • Table-based layouts: Email clients like Outlook demand clunky HTML tables that are a pain to code.
  • Inconsistent rendering: Your signature looks great in Gmail but breaks in Apple Mail or Thunderbird.
  • Time sinks: Tweaking fonts, spacing, and images to work across clients is a nightmare.
  • Closed-source tools: Most solutions hide their code and lock you into their ecosystem.
  • Overpriced subscriptions: Paying monthly for something so basic feels wrong.

MySigMail solves this. It’s a free, open-source, client-side tool that empowers you to create polished email signatures with ease. I built app to make professional signatures accessible to everyone—especially developers who value customization and openness.

What You Get

  • Deep Customization: Tweak fonts, colors, avatar shapes, social icons, and custom fields to match your style or brand.
  • Ready-to-Use Templates: Kickstart your design with clean, professional layouts.
  • Flexible Add-Ons: Add disclaimers, call-to-action blocks, and more to make your signature stand out.
  • Lightweight & Client-Side: Run it locally with no server setup required, perfect for developers who want simplicity.

Why Open-Source?

Open-source email signature generators are rare. Most tools are proprietary, expensive, or both. MySigMail is my contribution to the developer community—a transparent, customizable tool you can trust and extend. Whether you’re a solo dev or part of a team, MySigMail gives you the freedom to create signatures without the usual headaches.

Let’s Hear from You!

I’d love your feedback:

  • Would you use a client-side, open-source email signature tool?
  • What features would make it even better for your workflow?

Check out the project on GitHub: https://github.com/antonreshetov/mysigmail. I hope MySigMail helps you craft signatures that look great and feel effortless.

Cheers,
Anton
