Email Signature Generator Online

Building an email signature that actually renders correctly across Gmail, Apple Mail, and Outlook is notoriously frustrating because email clients use outdated rendering engines. This generator is built to output perfectly structured, battle-tested HTML signatures without you needing to write a single line of inline CSS.

The Outlook Rendering Problem

Modern CSS like Flexbox or Grid completely breaks in desktop versions of Microsoft Outlook, which still uses the Microsoft Word rendering engine to display HTML emails. To solve this, all the templates generated by this tool rely on heavily nested HTML <table> structures and strict inline CSS tags (style="color: #000"). This guarantees your signature won't collapse or break when sent to corporate clients.

Hosting Your Logo

The biggest mistake people make is trying to drag-and-drop a .png file into their email client's signature box. This attaches the image as a bulky file on every single email you send. Instead, this tool requires an image URL. You must host your logo on a public server (like your website) so the email client simply references the image instead of attaching it.

Retina Display Trick

To prevent your logo from looking blurry on high-density mobile screens (like iPhones), upload a logo to your server that is twice the size you want it to appear (e.g., 400x400px), but constrain the signature template settings to display it at 200x200px.
