Email Header Analyzer
Paste raw email headers to trace delivery, auth, and routing
How to get raw headers
- •Gmail: Open the email → ⋮ (three dots) → Show original → copy everything above the blank line
- •Outlook: File → Properties → Internet headers box
- •Apple Mail: View → Message → All Headers, then cmd+A to copy
- •Thunderbird: View → Message Source (Ctrl+U), copy the header section
Header parsing runs entirely in your browser. The live DNS check for SPF/DKIM/DMARC records uses Google's public DNS-over-HTTPS API — only the sender domain is queried, never the email contents.
