Email header analyzer

Paste an email’s raw headers to see its route, SPF, DKIM, DMARC results and phishing signs.

You can paste the whole message. The body is skipped, never read or stored.

Where do I find the raw headers?
  • Gmail: open the message → three dots → "Show original".
  • Outlook: open the message → three dots → View → "View message details".
  • Thunderbird / Apple Mail: open the message → "View source" (Ctrl+U).

Paste the raw email headers and press Analyze.
