Email Header Analyzer
Parse email headers to trace delivery path, check authentication status, and identify issues.
Understanding Email Headers
Email headers contain metadata about the message — who sent it, which servers it passed through, and whether authentication checks passed.
Key Headers
- From / Return-Path — Sender information
- Received — Server hops the email took
- Authentication-Results — SPF, DKIM, DMARC pass/fail
- Message-ID — Unique email identifier
- X-Spam-Status — Spam filtering results
