ProSignature is an email signature platform for professionals and small teams: design a branded signature in minutes, install it into Gmail in one click, roll it out to your whole team.

ProSignature is an email signature generator and management platform at prosignature.co. It does three things. First, it builds a professional email signature from your brand automatically: you enter your work email, and your logo, brand colours and social links are imported from your website rather than assembled by hand. Second, it installs that signature directly into Gmail through Google's API in one click, which removes the copy-paste step where most signatures are broken; Outlook, Microsoft 365 and Apple Mail are supported through clean copy-paste HTML. Third, it deploys signatures across a team: an administrator locks the design, branding and disclaimer while each employee's own name, title and phone are filled in, and every person connects their own mailbox in a click — with no Google Workspace or Microsoft 365 admin access required.

AI Banner Maker, handwritten signature maker, out-of-office message generator, email disclaimer generator and email sign-off generator — all free and client-side.
WiseStamp, Exclaimer, MySignature, Newoldstamp, HubSpot's free generator and Maileroo. We publish dated, verified comparisons rather than claiming to win every case.
Every competitor claim we publish is checked against that company's live pricing or feature page on the day of writing, and the date is printed on the page. Where a competitor is genuinely the better choice we say so explicitly — for example, Exclaimer is a better fit than we are for large, IT-administered organisations needing server-side enforcement, and WiseStamp has a deeper add-on ecosystem than ours. We do not publish invented ratings, fabricated reviews or unsubstantiated superlatives. Our full honest roundup of the market is at best email signature generators, and the market's watermark policies are compared at free with no watermark.
Written and maintained by the ProSignature team. Competitor pricing and feature claims on this site are verified against each vendor's live page on the day of writing — last verified 26 July 2026. No affiliate links. How we work.
