Create a professional email signature in seconds
Create professional HTML email signatures for free. Works with Gmail, Outlook, Apple Mail, and more. Just fill in your details, preview, and copy to your clipboard.
A professional email signature is a digital business card attached to every message you send. It reinforces your brand, provides recipients with contact information, and adds credibility. Good signatures include name, title, company, phone, and one or two relevant links. Bad ones include inspirational quotes, giant logos, animated GIFs, and ten social media icons. This generator creates clean, cross-client-compatible HTML signatures that render correctly in Gmail, Outlook, Apple Mail, and mobile email apps. Email HTML is notoriously tricky — what works in a browser often breaks in Outlook's Word-based renderer. The templates use table-based layouts and inline styles for maximum compatibility.
Outlook uses Microsoft Word's rendering engine, not a browser engine. This means no CSS flexbox, grid, or many modern properties. Table-based layouts with inline styles are the only reliable approach — which is what this generator uses.
Keep it under 10KB for fast loading. Use small, optimized images (max 200px wide for logos). Include 3-5 lines of essential info. Anything longer gets ignored or, worse, triggers spam filters.
Only include platforms you actively use professionally. LinkedIn is almost always appropriate for business. Twitter/X for public figures and media. Skip personal Instagram, TikTok, or Facebook in professional contexts.
Go to Gmail Settings → See all settings → Scroll to Signature → Create new → Paste the HTML signature. This generator copies rich HTML that preserves formatting when pasted.
Heavy signatures with large images, external links, and complex HTML can slightly increase spam scores. Keep images small, host them reliably, and avoid using too many different fonts or colors.
