HTML email signature best practices
A good signature is short, readable, and boring in the best way — it works everywhere and doesn’t fight the email body.
Use tables, not modern CSS layout
Many clients strip flexbox and grid. Nested tables with inline styles remain the most reliable pattern. SigSnap generates table-based HTML for that reason.
Keep it short
- Name, role, company, and two contact methods are enough for most people.
- Avoid giant legal disclaimers in the signature itself; put those in a footer template if required.
- One accent color is plenty.
Images
- Host photos on HTTPS with a stable URL.
- Use a modest size (roughly 64–96px) so mobile views stay clean.
- Never rely on the image alone — include text contact details.
Links and tracking
Link email, website, and LinkedIn with normal https:// or mailto: URLs. Skip heavy tracking pixels in a personal signature unless you truly need them.
Privacy
Prefer tools that build the signature in your browser so your contact details aren’t uploaded to a third-party editor. SigSnap stores nothing on a server — your work stays on your device until you paste it into your mail client.
Test before you ship
Send one test to Gmail, Outlook, and your phone. Check dark mode, reply chains, and whether the photo loads on cellular data.
