Best practices for email signature deliverability
Email signatures are appended to every email you send. Badly coded signatures with broken HTML or heavy uncompressed images can trigger spam filters or distort message rendering.
HTML Table Layouts
Email clients like Microsoft Outlook still use the Microsoft Word HTML rendering engine. Using bulletproof table-based layouts ensures your signature never breaks.
Hosted Images
Never attach image files directly to every email signature. Always host your avatar and company logo on a fast public CDN (HTTPS) to keep message sizes under 100KB.
Clean Tracking Links
Ensure links to your website and social profiles use direct HTTPS URLs. Broken redirects or suspicious shortlinks inside signatures can increase your spam score.
