MailSign review (2026): is the free plan enough?
Company email signatures for Gmail and Outlook, with a free generator
Black Friday: is there a MailSign sale?
Our verdict
Third of our top three email signature tools
For: One person who wants a free signature for Gmail or Outlook
MailSign's free generator lets anyone build a signature from 10 layouts with their own logo, colors and links, then copy it into Gmail or Outlook. Unlike WiseStamp's free plan, its listing does not limit it to personal webmail. It is third because it does far less than a managed service: you paste the signature in yourself, deployment, directory sync and audit logs are team features, team pricing is not published so the step up needs a quote, the Outlook route for teams needs its add-in and the Gmail route needs Google Workspace, and it runs in a browser only.

Best for a free signature generator with team deployment
MailSign is a free signature generator for one person, plus a paid Teams product for Gmail and Outlook deployment, directory sync and audit logs. Team prices are not published, and the free version means pasting the signature in yourself.
Who MailSign is for
- Fits if you are one person who wants a tidy signature without paying
- Works for companies that want to talk to sales about a deployed signature
Who MailSign is not for
- Skip it if you want a team price on the page, because none is published
- Tight if you use the free generator, since you copy the signature into Gmail or Outlook yourself
- Watch out: deployment, sync and audit logs are team features only
- Watch out: Outlook signatures need the MailSign add-in, and the Gmail route needs Google Workspace

Keep MailSign, or make your own?
Your call
You could make the core of MailSign for yourself: email signature and templates.
What you would give up is listed below. Whether that is worth the price is your call.
What you could make
- Email signature and templates: an app builder makes these well.
- It runs in a browser, which is where something home-made would run too.
What you could not
- It plugs into other products, Google Workspace, Gmail and Microsoft 365 among them.
- What a company asks for before it lets staff use something: audit logs and roles and permissions.
What this rests on. MailSign’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is MailSign?
MailSign has a free signature generator that anyone can use and copy into Gmail or Outlook, and a team product that deploys one company signature to Google Workspace mailboxes and to Outlook through an add-in. Teams set up locked templates, field permissions, directory sync and audit logs. Team pricing is not published.
Worth knowing
- Team pricing is not published; companies contact the vendor and are set up by hand.
- The free generator produces a signature you paste in yourself; deployment, sync and audit logs are team features.
- Outlook signatures depend on the MailSign add-in being installed, and the Gmail path needs Google Workspace.
Key features
- Free signature generator
- Anyone can build a signature from 10 layouts with their own logo, colors and links, then copy it into Gmail or Outlook.
- Gmail deployment
- After connecting Google Workspace, an admin edits the template and deploys it, and every mailbox gets the new signature.
- Outlook add-in
- Outlook users sign in with a Microsoft account and the add-in, listed on Microsoft AppSource, adds the right signature.
- Locked fields and permissions
- Admins choose which fields staff can edit, such as name or phone, while logo, layout and colors stay locked.
- Directory sync
- Titles, phone numbers and photos can be entered in MailSign or synced from Azure AD or SFTP, and new hires get a first signature from the company default.
- Audit log
- Team accounts include an audit log of changes.
