Email header analyzer

Paste raw headers (Gmail “Show original”, Outlook “View source”) or drop a .eml. Get the delivery hop chain, SPF/DKIM/DMARC verdicts, DKIM-Signature details, spoofing indicators, and a derived risk verdict — every result traced to the actual parsed headers.

Runs entirely in your browser — nothing is uploaded and no network request fires on use.

Paste headers above (Gmail “Show original”, Outlook “View source”, or any raw message) — the analysis appears here instantly. Nothing is sent anywhere.
