Install the email signature you made on fairsig.com into Gmail or Outlook on the web in one click. Fairsig puts the email signature you designed on fairsig.com into Gmail or Outlook on the web, without copy-paste. How it works 1. Make your signature on fairsig.com (free, no sign-up). 2. Click "Install in Gmail" or "Install in Outlook". 3. Your signature settings open with a small Fairsig panel. Click "Insert signature". 4. Check the result and click Save. Fairsig never saves for you. What it does • Opens the signature settings of Gmail (choose which signed-in account) or Outlook on the web (work/school or personal account). • Creates a new signature named "Fairsig", or replaces the one you are editing, and inserts your signature into the editor. • Highlights the Save button and tells you how to make it the default for new emails and replies. • If the editor can't be found, it copies the signature to your clipboard and shows the manual steps, with a link to the illustrated guide. Private by design • No account, no sign-in, no Google or Microsoft permissions (no OAuth). • No analytics, no tracking, no remote code. The extension makes no network requests. • Your signature only travels from the fairsig.com tab to the extension inside your browser, is kept in memory until you insert it, and is then deleted. • It only runs on fairsig.com messages and on the Gmail / Outlook web pages, and only shows its panel when you have a signature waiting. Interface in English, German, French and Arabic (right-to-left). Fairsig is an independent product, not affiliated with Google or Microsoft. Gmail is a trademark of Google LLC; Outlook is a trademark of Microsoft Corporation.
