HTML email signatures allow you to include formatted text, images, links, and social icons in your signature. Here is everything you need to know about creating one that works everywhere.
Why HTML Signatures?
Plain text signatures are limited. HTML lets you add your company logo, headshot, social media icons, and promotional banners — all formatted with consistent branding.
The Easy Way: Use a Generator
The simplest approach is using our free email signature generator. Design your signature visually and export clean, table-based HTML that works across all email clients.
The Manual Way: Write HTML
If you prefer to code your own, use table-based layouts (not divs or flexbox), inline CSS styles, and keep your total width under 600px for best compatibility.
Testing Your Signature
Always send test emails to yourself on multiple devices and email clients to verify your signature renders correctly.
