Email Header Analyzer
Analyze raw email headers to trace the routing path, inspect authentication results (SPF/DKIM/DMARC), and troubleshoot deliverability issues.
How the Email Header Analyzer Works
Paste the raw source code of an email. The tool parses the standard RFC headers, reading the "Received" lines backwards to map the journey, and extracts the "Authentication-Results" headers.
✅ Key Features
- Hop Extraction
- Delay Calculations
- Auth Results Parsing
- Spam Score Extraction
Frequently Asked Questions
How do I get my email headers?
In Gmail, click the three dots next to reply and select "Show original". In Outlook, go to File > Properties and look at "Internet headers".
What should I look for in the analyzer?
Look for the "Authentication-Results" section. You want to see "pass" for SPF, DKIM, and DMARC. Also look at the time delays between hops to identify bottlenecks.
