Best Animated Email Signature Generators in 2026, Compared

The best animated email signature generator depends on one question: do you already have an animation? If you don't, Overbrand makes one from your website today, free during its beta, and DocsAura is opening a similar tool with early access. If you do, WiseStamp, MySignature and Gimmio will host it in a signature for between $4 and $9 a month. Canva is the choice when you want to design the GIF by hand.

Full disclosure: DocsAura is our product, so read our row with that in mind. We checked every other row on the vendor's own pages on 30 October 2026, and we say below where we couldn't confirm something.

If you don't have an animation yet

Most signature tools assume you already have a GIF. Two start from your website instead.

Overbrand asks for your work email and domain, then sends a kit page with a looping card, usually the same day. Its AI agents read your site and animate the card, and a person checks each one. It's free during the beta, with no price announced after that. Its sample cards are good, and it's the one to try if you want a card today.

DocsAura's version takes the same input and aims to show three cards while you wait, with no human in the loop. In our two full test runs on one real company's site, three finished cards took 172 and 82 seconds, and the slower run kept retrying a bad photo. That's too few runs to promise a speed. It's in early access, so you can't make one yet. Free cards carry a small mark.

WiseStamp sits between these and the rest. Its animation feature alternates two photos you upload, at 120 × 120 pixels. That's a simple way to add movement to a headshot or logo, though it won't produce a card with a message on it.

If you want to design it yourself

Canva is the obvious pick. Free accounts can export GIFs up to a minute long at up to 1280 × 720, and paid accounts up to two minutes at 1920 × 1080. You get full control, and you do all the work: layout, timing, keeping the file small, then getting the GIF into your mail app.

Canva also has a free signature maker, though it isn't built around animation. We found no Canva help page covering an animated GIF in a Gmail signature, so test yours by sending it to yourself first.

Keep an eye on file size. Canva's limits are about export, and a 1280 × 720 GIF is far bigger than anything you'd want under an email. Litmus suggests staying under 1 MB for animated GIFs in email, so export at a small size and check the result.

If you have a GIF and need somewhere to put it

These tools are mostly about the signature around the GIF: layout, contact details, and hosting the file so it loads.

• MySignature gives you a gallery of static and animated banners, and lets you upload one of your own. We couldn't confirm whether the free plan includes animated banners.
• Newoldstamp puts banners on its paid plans. It suits people who want one signature for a flat yearly fee.
• Gimmio is the only one here with a one-off option: $7 for a single signature, no subscription. Its domain is gimm.io, because gimmio.com goes to a domain sale page.
• HubSpot's generator is free with no account, and a sound choice for a clean static signature. It doesn't mention GIFs anywhere we looked.

If you need it across a whole company

Exclaimer applies signatures centrally across Microsoft 365 and Google Workspace, so nobody has to paste anything. Animated GIFs are supported for campaign banners, up to 600 pixels on either side. WiseStamp also has higher tiers for this. Both matter more once you have enough people that someone keeps forgetting to update their signature.

What every tool has to work around

No generator can change how mail apps behave, and a few limits apply whichever you pick:

• Outlook on Windows may show only the first frame. Microsoft says newer versions play animations unless they're turned off in Windows, while email testers report first-frame-only behaviour on versions through 2019. Your first frame has to make sense alone.
• Google states a size limit. Its help page gives a maximum signature image of 100 pixels high by 1000 wide. Several tools ship taller cards, ours and Overbrand's included at 160 pixels. Google doesn't say what happens above the limit, and we haven't finished testing it, so send yourself a test.
• Apple says iPhone and iPad signatures are text only. Its iPhone guide says so directly. Vendor guides that describe a workaround go beyond what Apple supports.

Our separate guide covers adding a GIF signature in each mail app, step by step.

What we couldn't confirm

Prices and features change, and a few things stayed out of reach on 30 October 2026. We saw Canva's price only in Polish złoty. WiseStamp's own pages disagree on whether new users can still get its free plan. We didn't submit HubSpot's or Gimmio's forms, so we can't say whether their free output carries branding. And we couldn't find any independent study of how animated signatures affect replies or deliverability, so treat any tool's claims on that with care, including anything you read from us.

How to choose

Run the question in order. No animation and no time: use a tool that starts from your website. A strong idea and an afternoon: design it in Canva. A GIF already made: pick the cheapest signature tool that accepts it. Fifty people to keep in line: look at Exclaimer or WiseStamp's team plans.
