You don't need an account, a credit card, or design skills to get a professional email signature. The generator above does the whole job in your browser: type your name, title, company, email, phone and website, pick one of three templates, choose your brand color, and watch the preview update as you type. When it looks right, click Copy HTML and paste it into your email client's signature settings. That's it — it works today, and it's free.
Why does the output actually render properly everywhere? Because it's built the boring, correct way: tables and inline styles, the same technique professional signature tools use, so it holds together in Gmail, Google Workspace, Outlook (desktop, web and Microsoft 365) and Apple Mail instead of breaking apart the first time someone opens your email on a phone.
A few honest details. Everything runs locally in your browser — your details are never sent anywhere. There is no watermark on your information. Free signatures do include one small "Created with FlatSign" line at the bottom; that's the trade, and it's disclosed rather than hidden. If you're creating a signature for just yourself, you're done — enjoy it, no catch and no follow-up sales sequence.
Where a free generator stops being enough is the moment there's a team. One signature is a two-minute job. Twenty-five signatures — kept consistent every time someone is hired, promoted, or the logo changes — is an ongoing chore that usually lands on whoever manages ops or IT, and it quietly drifts until half the company is emailing under three different versions of the brand.
That's what FlatSign, the manager behind this tool, is being built for: one template, every employee's signature generated and deployed centrally, banner campaigns when you want them — all for one flat price per company with unlimited seats, instead of the category's usual $4–$12 per user/month (at a typical $6 a seat, 25 people = $150/mo). FlatSign is in beta now; waitlist members get first access and founding pricing locked in.
Build your free signature above — and if a whole team needs matching ones, join the beta waitlist.
