Stop fighting Gmail's signature editor. ProSignature designs your signature and writes it straight into your Gmail settings — logo, photo, links and all.
Gmail's signature box is a plain text field. Getting a logo, a photo and neatly aligned social icons to look right means wrestling with copy-paste, and the formatting often breaks the moment you send. ProSignature skips all of that — it builds the signature and installs it for you.
Instead of copying HTML and hoping it survives, ProSignature connects to Gmail and writes the signature directly into your account settings. It appears on new emails automatically — on desktop and the mobile app.
You can also copy the finished signature and paste it into Gmail's signature settings manually — ProSignature formats it so it holds together. Either way you end up with a clean, professional result. Setting up a whole company? Use the team plan to deploy signatures across everyone's Gmail at once.
Three classic failures: pasted signatures lose their formatting (Gmail's editor rewrites messy markup), images break (they must be hosted on public HTTPS, not attached), and the signature silently doesn't apply to replies (a separate default nobody notices). ProSignature sidesteps all three — it puts clean, hosted, inline-styled HTML into every Gmail compose via a no-permission Chrome extension, and can optionally write it into Gmail's signature setting for new mail and replies in one action. And with the free Chrome extension, the signature also appears in every compose window automatically — no Google permission needed.
