The Best Free Email Signature Generators in 2026

Search “free email signature generator” and you’ll find dozens of tools. The trouble is that “free” often comes with strings: watermarks, tracking, locked exports, or a per-user bill the moment you add your team. Here’s how to judge them properly.

What “free” should actually mean

• Free to design and export working HTML — not a preview you can’t use.
• No watermark or forced branding in your signature.
• No tracking pixels quietly added to your emails.
• Cross-client output that renders in Outlook, Gmail and Apple Mail.

The catches to watch for

Per-user pricing. Many tools are free for one signature but charge monthly per employee — costs escalate fast for teams. Tracking. “Free” tools sometimes monetise by embedding open-tracking, which is a GDPR risk. Lock-in. Some won’t let you export clean HTML, so you can’t leave.

How Mirosign compares

Mirosign is free to design and export a working signature, adds no tracking, and — unusually — doesn’t charge per user for teams. You can also import your own HTML if you already have a design.

Choosing the right one

For a single freelancer, almost any reputable tool works — just avoid tracking and watermarks. For a team, the deciding factor is usually pricing model and consistency: a per-user tool that looks cheap at five people is expensive at fifty.
