Analyze an Email Header

Paste the complete raw headers below

In your email client, look for “Show original,” “View source,” or “Internet headers.” Copy the full header section, preserving its line breaks.

Headers are submitted to this server for analysis. They may contain email addresses, IP addresses, and internal hostnames. Only submit information you are authorized to share.

Trace the route

Review the servers listed in the delivery chain and inspect the recorded transfer times.

Investigate delays

Compare hop delays and review the generated timing chart when available.

Review security headers

Inspect the message’s reported authentication and security fields. Header claims are not an independent verification of the sender.
