Email Signature Generator creates HTML email signatures that render consistently across Gmail, Outlook, Apple Mail, and Thunderbird. It produces table-based layouts (the only reliable method for cross-client compatibility) with inline CSS styles, properly sized social media icons, and formatted contact information. The tool handles the notorious Outlook rendering quirks including its use of the Microsoft Word HTML engine, which ignores modern CSS and requires VML for some formatting.
Marketing teams standardizing company email branding, professionals creating personal signatures, and IT administrators deploying organization-wide email signature templates. The tool runs entirely in your browser — your data never leaves your device.
