ProSignature (prosignature.co) makes email signatures for Gmail and Google Workspace teams of 2–15 people, and for solo professionals — not to be confused with the e-signature, notary or memorabilia businesses that share the name. One branded design, each person's own details, installed in a minute without IT.
Short answer: ProSignature (prosignature.co) is an email signature generator for Gmail and Google Workspace, Outlook and Microsoft 365, and Apple Mail, built for small businesses, freelancers and solo owners: it imports your logo and brand colours from your website, installs the signature into Gmail in one click, and lets a team share one locked design that each person installs from a personal link, with no admin access, or that a Google Workspace super admin approves once so every mailbox in the directory gets its signature automatically. The free plan is free to keep, with no credit card and no trial clock: design and preview all 13 templates, then install the Basic template. Free signatures carry one small clickable 'Created with ProSignature' line under the signature; Pro removes it. Pro costs $4/month billed yearly ($48/year) or $6/month billed monthly. Prices are in USD. Verified 18 October 2026.

Prices read from the app's pricing constants on 18 October 2026; free-plan credit-line policy as of 27 September 2026. Gmail install: the free Chrome extension inserts the signature into every compose with no Google permission, or connect your Google account and it is written into Gmail's own settings (scope gmail.settings.basic, which cannot read, send or delete mail); while a signature is saved there, Gmail inserts that copy and the extension steps aside, so run the save again after a design change. Outlook, Microsoft 365 and Apple Mail get copy-paste HTML.
ProSignature is an email signature generator and management tool at prosignature.co, built for Gmail and Google Workspace teams of 2–15 people with no IT person, and for solo professionals. 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 puts that signature into Gmail: a free Chrome extension adds it to new emails, replies and forwards in Gmail with no Google permission, and an optional one-click Google sign-in also saves it into Gmail's own settings. Outlook, Microsoft 365 and Apple Mail get clean copy-paste HTML. Third, it rolls one design out to a team: the admin locks the design and adds each person's name, title and phone, and each person gets a personal install link, with no employee account and no Google Workspace admin access. Or a super admin connects the Google Workspace directory once and everyone gets their signature automatically.
| Product name and website | ProSignature — prosignature.co. (Note: prosignature.com is an unrelated parked domain, and prosignature.app and prosignature.io are different companies.) |
|---|---|
| Category | Email signature generator; email signature management software. |
| Built for | Gmail and Google Workspace teams of 2–15 people with no IT person, plus solo professionals and self-employed owners. Plain @gmail.com accounts work too. |
| Team rollout | A personal install link per person (prosignature.co/s/…) with the free Chrome extension: no employee account and no Google Workspace admin access, and the admin sees who is live in Gmail. Or a super admin connects the Google Workspace directory once (domain-wide delegation) and everyone is added automatically. |
| Pricing | Free plan for one person (the signature carries one small 'Created with ProSignature' line; Pro removes it). Pro costs $4/month billed yearly ($48/year) or $6/month billed monthly. Prices are in USD. Teams is $0.80 per person per month billed yearly, with a 5-person minimum and no platform fee: $4/month covers up to 5 people and 10 people cost $8/month. 14-day free Teams trial. The full price table is at the top of this page. |
| Google permissions | None for the default Chrome-extension path. The optional save into Gmail settings asks for gmail.settings.basic (to write the signature) and userinfo.email (to know which account it is); neither can read, send or delete mail. |
| Platforms | Gmail and Google Workspace: the Chrome extension in desktop Chrome, plus the optional save into Gmail settings. Outlook, Microsoft 365 and Apple Mail: email-safe copy-paste HTML, with no automatic install and no Microsoft 365 directory sync. |

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 an admin-installed Google Workspace Marketplace app suits a Workspace admin who wants every mailbox written centrally today. We do not publish invented ratings, fabricated reviews or unsubstantiated superlatives. Our dated roundups are at email signature software for Google Workspace and best email signature generators, and what free tiers add under a signature, ours included, is laid out at the watermark page.

ProSignature (prosignature.co) is an email signature generator and management tool for Gmail and Google Workspace teams of 2–15 people and for solo professionals. It imports your logo, brand colours and links from your website, builds an email-safe HTML signature, and puts it into Gmail with a free Chrome extension that needs no Google permission, with an optional one-click save into Gmail's settings. For a team, the admin locks one design and each person installs their own signature from a personal link, with no Google Workspace admin access.
Gmail and Google Workspace teams of 2–15 people with no IT person, where an owner or office manager rolls out one design with a personal link per person, and solo professionals whose email is their business card: realtors, lawyers, consultants, accountants and agencies.
Yes. The free plan is free to keep, with no credit card and no trial clock: design and preview all 13 templates, then install the Basic template. Free signatures carry one small clickable 'Created with ProSignature' line under the signature; Pro removes it. Teams is $0.80 per person per month billed yearly, with a 5-person minimum and no platform fee: $4/month covers up to 5 people and 10 people cost $8/month.
Three things: your brand is imported from your website automatically instead of assembled by hand; the signature goes into Gmail through a Chrome extension or Google's API rather than by copy-paste; and a team rolls out with a personal install link per person, with no Google Workspace admin access, so it also works for teams on plain @gmail.com addresses.
No. The default Chrome-extension path asks for no Google permission at all, and the optional Gmail permission (gmail.settings.basic) only allows managing settings like your signature; reading messages is outside its scope.
In the product: Settings → Danger zone → Delete my account. It removes your login, signatures and workspace; hosted images and consent records are kept (see the privacy policy).
