An open-source email signature generator for Gmail, Outlook, Apple Mail, etc.
Build a sleek, professional-looking signature that enhances your brand.

Creating an email signature is not a trivial task, especially for non-technical people. Most existing solutions are either paid or closed-source.

MySigMail makes it easy, free, and open-source. Let’s make creating professional signatures accessible for everyone!

• Customization – fonts, colors, avatar shapes, social icons, custom fields
• Templates – ready-to-use layouts for quick start
• Add-ons – disclaimer, call-to-action, and more

The project uses Bun for building and running. Please make sure you have Bun installed.

git clone https://github.com/antonreshetov/mysigmail
