Free Email Signature Generator / Compare / Exclaimer
Exclaimer is enterprise signature infrastructure: centrally applied signatures, disclaimers, compliance controls and analytics for organisations with hundreds or thousands of mailboxes, priced per user. SignatureGen is at the opposite end on purpose — one person, one signature, 30 seconds, $0.
There are workplaces where a signature is a compliance surface: legal disclaimers must appear, designs must be locked, and signatures must apply identically from every device whether employees cooperate or not. Exclaimer exists for exactly that world, integrating with Google Workspace, Microsoft 365 and Exchange with minimum seat counts and serious admin tooling. That is a legitimate enterprise purchase.
It is also irrelevant to most signature searches, which come from individuals. SignatureGen makes the personal version of the same asset: a circular transparent headshot, name, title, website and social links, exported as robust table HTML for Gmail, Outlook and Apple Mail. It's free because it's a webpage, not a platform — no seats, no minimums, no procurement.
| What matters | SignatureGen | Exclaimer |
|---|---|---|
| Price for one professional signature | Free — $0, no paid tier required for the core tool | Per-user enterprise subscription, typically with a minimum number of users |
| Sign-up / account required | No — open the page and build | Yes — organisation account, admin setup |
| Watermark or branding on free use | None | Signatures (and disclaimers) are centrally designed by your organisation |
| Circular headshot with transparent background | Yes — circular crop, border ring, transparent PNG download | Photos supported within managed designs |
| Social links (TikTok, LinkedIn, Facebook, Instagram, X) | Yes — TikTok, LinkedIn, Facebook, Instagram, X (handle or URL) | Social icons and banners supported in designs |
| Raw HTML export | Yes — copy rich signature, copy raw HTML, or download HTML file | Signatures are applied centrally/server-side rather than pasted by each user |
| Photo privacy (nothing uploaded) | Yes — photo is processed in your browser, never uploaded | Organisation mail flow and data sit inside an enterprise service |
| Central team management / admin console | Not built for that — each person makes their own in 30 seconds | Yes — central application across clients and mobile devices |
| Banner campaigns & signature analytics | No — this is a generator, not a campaign platform | Yes — scheduling, targeting, analytics and A/B testing on higher tiers |
| Best for | Individuals, freelancers, creators and small teams who want it done now | Global and regulated enterprises needing governed, compliant signatures at scale |
Competitor details reflect public product positioning at the time of writing and change often — check Exclaimer directly for current plans, pricing and features. This is a comparison, not a hands-on review.
Upload a square headshot, add your name, title, website and socials, and copy a signature that works in Gmail, Outlook and Apple Mail. It takes about 30 seconds — and unlike a paid plan, there's nothing to cancel.

Exclaimer sells ongoing central management, application and governance for every mailbox in a company. SignatureGen is a one-time generator in your browser — there's no service running for you afterwards, so there's nothing to charge rent on.
Not automatically. You can paste your own disclaimer text under the signature in your email client's signature editor. If disclaimers must be enforced company-wide, that's an Exclaimer-style job.
For small teams, yes — everyone makes their own in 30 seconds. Once you need central enforcement, disclaimers and analytics, you've outgrown a generator and should look at enterprise platforms.
