About this tool
Paste the raw headers from any email — available via 'Show original' in Gmail or 'Properties → Internet headers' in Outlook — and get a clean breakdown of key fields, SPF/DKIM/DMARC authentication results, spam score, and a hop-by-hop delivery timeline with timestamps and inter-hop delays. Diagnose delivery problems, spot suspicious relays, and verify authentication without decoding the raw header blob manually.
