About This Tool
A clean email signature is a small thing that quietly signals you are a real professional, not a spammer, and it gives every reply a clear next step (your phone, your site, your LinkedIn). This free email signature generator builds one in under a minute. Enter your name, title, company, phone, email, website, and LinkedIn, then pick one of four templates (Minimal, Modern, Compact, or Bold accent) and an accent color.
You see a live preview update as you type. When you are happy, copy the rendered signature with one click and paste it into Gmail, Outlook, or Apple Mail, or copy the raw HTML source if you prefer to drop it into a signature manager. Every signature is built with email-client-safe inline styles, so it renders consistently across inboxes instead of breaking the way CSS-heavy signatures often do.
No signup, no watermark, no card. The tool runs entirely in your browser, so none of your details are stored or sent anywhere. A signature is the last touch on an email; the first touch is reaching the right person. That is what Cleanlist does for sales and GTM teams: find and verify prospect emails and direct dials across 15+ providers (98% email accuracy, 85% phone) and enrich every contact with AI columns so outreach is personalized at scale.
Polish your signature here, then build a verified contact list to send from it.

Frequently Asked Questions
Is this email signature generator free?
+
Yes, completely free with no signup, no watermark, and no card. Build as many signatures as you want. The tool runs in your browser, so your details are never stored or sent anywhere.
Will the signature work in Gmail and Outlook?
+
Yes. The signature is generated with email-client-safe inline styles so it renders consistently in Gmail, Outlook, and Apple Mail. Use the Copy signature button to paste the formatted version directly into your email client's signature settings, or copy the raw HTML source for signature managers.
How do I add the signature to Gmail?
+
Generate your signature, click Copy signature, then in Gmail go to Settings, scroll to the Signature section, create a new signature, and paste. Save changes at the bottom of the settings page. The formatting, links, and accent color carry over.
Can I customize the colors and layout?
+
Yes. Choose from four templates (Minimal, Modern, Compact, and Bold accent) and pick an accent color, including presets. The live preview updates as you type so you can see exactly how the finished signature looks before you copy it.
What should a professional email signature include?
+
Keep it to the essentials: full name, job title, company, one phone number, and one or two links (website and LinkedIn). Avoid large images, long quotes, and multiple competing calls to action, which can hurt deliverability and look cluttered. A clean, text-light signature renders reliably and reads well on mobile.
