Email Header Analyzer
Trace email routing paths, detect spoofing attempts, and analyze authentication with our comprehensive email header analysis tool. Perfect for investigating suspicious emails and understanding email delivery.
Analyze Email Headers
How to find email headers:
- Gmail: Open email → 3 dots → Show original
- Outlook: Open email → File → Properties → Internet headers
- Apple Mail: View → Message → All Headers
- Yahoo: Actions → View Full Header

Frequently Asked Questions
How do I find email headers?
Email headers location varies by client: Gmail - open email, click 3 dots, "Show original"; Outlook - File → Properties → Internet headers; Apple Mail - View → Message → All Headers; Yahoo - Actions → View Full Header.
What can email headers tell me?
Email headers show the complete routing path, including all servers the email passed through, timestamps, IP addresses, authentication results (SPF, DKIM, DMARC), and potential spoofing indicators.
How does spoofing detection work?
Our tool analyzes SPF/DKIM/DMARC authentication results, checks for domain mismatches between sender and Message-ID, examines routing inconsistencies, and identifies suspicious header patterns commonly used in phishing attempts.
What are SPF, DKIM, and DMARC?
SPF (Sender Policy Framework) verifies sending server authorization, DKIM (DomainKeys Identified Mail) ensures message integrity through cryptographic signatures, and DMARC (Domain-based Message Authentication) provides policy-based authentication combining SPF and DKIM.
Is it safe to paste email headers here?
Yes, we only analyze the routing and authentication information. However, email headers may contain email addresses and server names. We recommend removing sensitive content if analyzing confidential emails.
Why might an email show no routing path?
Missing routing paths typically indicate stripped headers (common with forwarded emails), direct server injection, or potentially suspicious email modifications. This can be a spoofing indicator but may also occur with legitimate internal systems.
