Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.4
GPA, above 11 of the 22 other email signature tools we grade
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.
To get you started, here are 8 things to know about MailSign, taken from its own pages and our grades.
The generator is quick, but teams need an Outlook add-in, Google Workspace and directory sync.
- 1
Best for a free signature generator with team deployment
Team prices are not published, and the free version means pasting the signature in yourself.
- 2
There is a free plan
The signature generator is free for anyone: 10 layouts, your logo, colors and links, copied into Gmail or Outlook by hand.
- 3
It runs on Web
Web.
- 4
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.
- 5
Gmail deployment
After connecting Google Workspace, an admin edits the template and deploys it, and every mailbox gets the new signature.
- 6
Outlook add-in
Outlook users sign in with a Microsoft account and the add-in, listed on Microsoft AppSource, adds the right signature.
- 7
A 2.4 GPA, above 11 of 22
That is against the other email signature tools we grade, on value, the free plan, features, ease of use and platforms.

The report card
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.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | Team pricing is not published and is arranged through sales, so the category comparison cannot be made. |
| Free plan and trial | B | The generator is free for anyone, with 10 layouts, your logo, colors and links, and one person could live on it. |
| Features | C | Generator, Gmail deployment, Outlook add-in, locked fields, directory sync and audit log. Deployment and sync are team features set up by hand. |
| Ease of use | C | No rating on record. The generator is quick, but teams need an Outlook add-in, Google Workspace and directory sync. |
| Platforms and integrations | B | Web service for Gmail and Outlook with Google Workspace, Microsoft 365, Azure AD and SFTP. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
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 it 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
Good to know
Good for
- Individuals who need a free formatted signature for Gmail or Outlook
- Companies on Google Workspace or Microsoft 365 that want one deployed signature
- Buyers who are happy to get a quote rather than see a price list
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.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
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.
