About Email Headers

Email headers contain metadata about the message including sender, recipient, routing path, timestamps, and authentication results. This tool parses headers according to RFC 822/5322 to help you:

  • Trace the route - See all servers the email passed through
  • Identify delays - Find where slowdowns occurred
  • Check authentication - Verify SPF, DKIM, and DMARC results
  • Detect spoofing - Identify potential spam or phishing

What is an Email Header Analyzer?

An Email Header Analyzer is a diagnostic tool that parses and interprets email header metadata. It reveals the complete journey of an email from sender to recipient, including all servers it passed through, timestamps, and authentication results.

Common Use Cases

Detect Phishing

Identify spoofed emails and potential phishing attempts.

Diagnose Delays

Find where email delivery slowdowns occurred in the route.

Trace Email Route

See all mail servers the email passed through with timestamps.

Verify Authentication

Check SPF, DKIM, and DMARC authentication results.

2

Analyze

We parse headers to extract sender, route, and authentication data.
