How it works

From blank to every inbox in three steps

01

Pick a layout

Choose one of 10 layouts, then add your logo, colours and links.

Company default
Default
Sales team
Template
Events
Template

02

Make it the company default

Save it as a template once. Everyone who joins later gets a correct signature from it.

Deploy signatureGmail
Every mailbox updated
Deploy

03

Roll it out

One click deploys it to every Gmail mailbox. In Outlook, the add-in takes care of it.

Built for teams

Control without the chasing

Admins set the rules once. MailSign keeps every signature correct after that.

Lock the brand, free the details

Logo, layout and colours stay locked. Names, titles and phone numbers stay editable, if you allow it.

Signed from day one

New people get their signature from the company default, with their real details.

Directory sync

Pull names, titles, phone numbers and photos from Azure AD or SFTP, so a promotion shows up in the signature too.

Audit log

Every edit and every deploy, logged with who did it and when.

Built for real inboxes

Looks the same when it lands

A signature only works if it survives the trip. MailSign builds them the way email clients expect.

Email-safe HTML

Signatures are built from tables and inline styles, the HTML that Gmail and Outlook render most consistently.

Deployed, not pasted

Admins push signatures to Gmail from MailSign and Outlook gets them through the add-in. No copy-paste, no broken formatting.

Hosted icons and links

Contact icons load from MailSign's CDN and long links become short links, so the signature stays light and tidy.

Small details

Every email works a little harder

QR codes

Add a scannable QR code to any signature, so people can reach you straight from their phone.

Short link

Short links

Long campaign URLs turn into short, clean links that fit the signature.

FAQ

Questions before you start?

The short version. More on the FAQ page.

Does MailSign work with Gmail and Outlook?

Yes. Google Workspace admins deploy signatures to every Gmail mailbox from MailSign. Outlook users get theirs through the MailSign add-in, which is listed on Microsoft AppSource.

Do employees need to install anything?

Not for Gmail: the admin deploys from MailSign and the signature appears. For Outlook, the MailSign add-in adds the signature.

Can employees change their own signature?

Only the fields you allow. Admins choose which fields are editable, like name or phone number, and which stay locked, like logo, layout and colours.

Is there a free version?

Yes. The free signature generator lets anyone make a signature and copy it into Gmail or Outlook.

Every email, on brand. Starting with yours.
