What Is Email Signature Generator?

The Email Signature Generator creates professional, responsive HTML email signatures that work across all major email clients including Gmail, Outlook, Apple Mail, and Thunderbird. A well-designed email signature serves as a digital business card in every email you send — it reinforces your brand, provides contact information, and can include social media links. This tool generates table-based HTML (the most compatible format for email clients) with your custom brand color, avatar initial, name, title, company, contact details, and social links. The visual preview shows exactly how your signature will appear.

Technical Guide

Email HTML is fundamentally different from web HTML. Email clients have inconsistent rendering engines, with Outlook using Microsoft Word's HTML renderer. For maximum compatibility, our signatures use: inline CSS (no external stylesheets), table-based layout (not flexbox/grid), web-safe fonts, and avoid CSS properties like float, position, and media queries. The generated HTML uses the table element for layout structure, inline styles on every element, and system font stacks. Colors are applied as inline hex values. Links use the appropriate protocol prefix (mailto:, tel:). The signature is designed to be compact — email signatures should be 3-4 lines visually to remain professional.

Tips & Best Practices

1
Keep signatures to 3-4 lines of information maximum
2
Use your brand color consistently for recognition
3
Include only essential contact information — quality over quantity
4
Test your signature by sending emails to different clients (Gmail, Outlook, mobile)
5
Update your signature when your role or contact info changes
