Email Signature - Clean & Private

Create elegant HTML email signatures. 100% open-source, zero tracking, and absolutely no permissions to read your mailbox.

Create clean, elegant, and professional HTML email signatures in seconds. 100% private, open-source, and strictly requires zero permissions to read your mailbox. Unlike traditional signature extensions that demand invasive access to your Gmail/Google Workspace account ("Read, compose, and send emails on your behalf"), Email Signature Kit operates entirely locally on your device. Key Features: - Zero Mailbox Permissions: We cannot and will never read, scan, or analyze your emails. - Dual-MIME Rich Clipboard: Automatically writes both text/html and text/plain to your system clipboard. When you paste into Gmail, Outlook, or Apple Mail, styles and layouts remain pixel-perfect. - Zero DOM Injection: Does not alter your webmail interface or inject intrusive floating buttons. - Ultra-Lightweight & Instant: Built with native TypeScript and Vite, resulting in a bundle size under 10KB that opens instantly. - Local State Persistence: Your contact info is saved only in your browser's local storage and never leaves your computer. How to Use: 1. Click the extension icon to open the signature generator. 2. Fill in your name, title, company, email, and phone. 3. Click "Copy Signature". 4. Open your email client settings (e.g., Gmail Settings -> General -> Signature) and paste (Ctrl+V or Cmd+V). Looking for team management, logo hosting, and 50+ vector-styled email templates?
