Why traditional signatures fail (and how we fixed them)

Most online generators create messy HTML that breaks in Outlook or ends up in spam. We engineered a bulletproof system.

Word Engine & Outlook Safe

Outlook uses Microsoft Word's rendering engine. We compile strictly nested HTML tables with zero broken flexbox or CSS variables.

Dual-MIME Clipboard API

Copies both rich formatted HTML and plain text simultaneously. Simply press paste (Cmd+V) in Gmail or Apple Mail settings.

Automated UTM Campaign Tags

Automatically tags all your links with UTM tracking so you can monitor clicks and leads directly in Google Analytics.

Frequently Asked Questions

How does the One-Click Copy work?

Our generator compiles your signature into a dual-MIME clipboard format containing both styled HTML and clean plain text. When you click 'Copy Signature', it writes directly to your clipboard so you can paste (Cmd+V or Ctrl+V) into Gmail, Apple Mail, or Outlook settings with zero formatting loss.

Will this signature look good on mobile phones (iPhone & Android)?

Yes! All templates use responsive table constraints with percentage and max-width definitions. We've verified that text, avatar photos, and CTA buttons re-flow cleanly on iOS Mail, Gmail for Mobile, and Outlook mobile apps.

Do I need to sign up or create an account to use the free builder?

No. You can immediately customize and copy your email signature without creating an account. Your draft is automatically saved in your browser's local storage so you won't lose your work.

Where should I host my profile avatar or company logo?

You can host your image on any public image hosting service, your company website, or platforms like Cloudflare R2 / Unsplash / Imgur, and paste the direct image link into the Avatar field.

How do I remove the 'Made with EmailSignatureKit' watermark?

The Free tier includes a discreet link at the bottom. Upgrading to the Pro Lifetime Pass ($29 once) removes all watermarks and gives you complete white-label access.
