Free Email Header Analyzer
Analyze email headers to trace email delivery path, check authentication, and troubleshoot delivery issues.
What are Email Headers?
Email headers contain metadata about an email's journey from sender to recipient. They include information about servers that handled the email, authentication results, spam filtering decisions, and much more. Analyzing headers helps troubleshoot delivery issues and verify email authenticity.
How to Find Email Headers
Gmail: Open email → three dots menu → "Show original" → copy headers. Outlook: File → Properties → copy "Internet headers" text.
What Our Analyzer Checks
Our tool analyzes SPF/DKIM/DMARC authentication, traces the complete delivery path through all servers, identifies spam filtering results and security threats, and extracts sender information, timestamps, and routing delays.
