Paste the full raw headers from any email to check SPF, DKIM, DMARC and ARC authentication results, view relay hops with delay timings, and parse all individual header fields.
The email header analyzer parses raw email headers (from Gmail, Outlook, Exchange or any mail client) to show SPF, DKIM, DMARC and ARC authentication results, trace each relay hop with timestamps and delay calculations, and display all header fields in an easy-to-read table. Useful for diagnosing email delivery failures, spam filtering issues and authentication problems.
