ProSignature — Gmail signature

Apply your ProSignature email signature to Gmail in one click.

Design a professional email signature on prosignature.co — logo, photo, social links, call-to-action — then install it into Gmail with one click. No copy-paste, no broken formatting. HOW IT WORKS 1. Build your signature at prosignature.co (free plan available). 2. On the Install step, click "Connect Gmail & install". 3. Approve Google's permission once — the extension writes the signature straight into your Gmail settings. 4. Open Gmail, hit Compose, and your signature is there. WHAT IT CAN AND CAN'T DO • Uses one narrow Google permission (gmail.settings.basic): manage basic Gmail settings such as your signature. It cannot read your email. • Your Google sign-in happens directly with Google — ProSignature never sees your password, and your access token never leaves your browser. • Works with personal Gmail and Google Workspace accounts. Made by ProSignature — professional email signatures for individuals and teams.
