Build a clean, branded email signature, preview it exactly as it will look, then copy it straight into Gmail, Outlook, or Apple Mail. Safe HTML, no bloat, no design skills needed.
Safe, email-client HTML
Table-based, inline-CSS signatures that render the same in Gmail, Outlook, and Apple Mail. No scripts, no broken layouts, no surprises.
Live, honest preview
What you see is exactly what you copy. Check it on desktop, mobile, and a dark background before you send.
Eight clean templates
Classic, compact, executive, minimal, soft card, logo banner, campaign CTA, and Arabic/RTL layouts with your logo, color, and social links.
Copy and install
One click copies the formatted signature. Step-by-step guides walk you through Gmail, Outlook Desktop, Outlook Web, and Apple Mail.
Plain-text fallback
Every signature also generates a clean text version, so it looks right even where images are blocked.

Create Free AccountWhat is SignatureKit?
SignatureKit is a free, mobile-first email signature generator built into SmartKit that lets anyone create a clean, professional, branded email signature and install it in Gmail, Outlook, or Apple Mail in minutes. You enter your name, title, company, contact details, and social links, choose one of three safe templates, add your logo and photo, pick an accent color, and see a live preview that is exactly what you copy. There is no design skill required and no risky HTML to hand-write.
What makes SignatureKit different from copy-and-paste HTML is that it produces conservative, email-client-safe HTML on purpose. Email clients are not web browsers, so SignatureKit builds table-based signatures with inline styles only, and never uses scripts, SVG, forms, or modern layout tricks that break in Outlook and Gmail. Every value you type is escaped and every generated signature is passed through a strict safety filter, so your signature stays clean, small, and compatible.
How it works
1. Pick a template
Start with Classic With Photo, Compact No Photo, or a Campaign banner. Each one is tuned to stay light and render correctly across email clients.
2. Enter your details
Add your name, job title, company, email, phone, website, WhatsApp, a booking link, and social profiles. Toggle any part on or off, and set your accent color and font.
3. Preview honestly
The live preview shows your signature on desktop, on mobile width, and on a dark background, with a health indicator that warns you if the signature is getting heavy or if a link is unsafe. What you see is exactly what you copy.
4. Copy and install
One click copies the formatted signature so you can paste it straight into your email signature box, and a built-in guide walks you through Gmail, Outlook Desktop, Outlook Web, and Apple Mail step by step. A plain-text version is generated automatically as a fallback.
