Email header parser

Paste the raw headers from any email and we'll trace the Received: chain, parse SPF / DKIM / DMARC results, and surface the from/return-path/reply-to triple so you can spot spoofing.

Runs entirely in your browser. Files and inputs never leave this page.

Need to run 100 of these at once?

The paid Tracelight platform runs this and 30+ other OSINT checks against a list of subjects with citation receipts for every claim.
