Raw Header

The Raw Header tab shows the complete email headers for the message. You can review header fields, search for specific values, and analyze authentication results.

In the Raw Header tab, you can do the following actions:

  • Copy raw headers: Click Copy raw headers to copy all message headers so you can paste them into another tool for further analysis.
  • AI Analysis: Click AI Analysis to generate an AI summary of the message headers. For more information, see AI Analysis.
  • Search keyword: Search for specific header names or values in the Search keyword field.
  • Sort headers: Click the column headers to sort the table.

Header details

The Raw Header tab lists all header fields detected in the message.

The table includes the following columns:

  • No.: The sequence number of the header entry.
  • Header Name: The name of the header field.
  • Header Value: The value associated with the header field.

These headers provide technical information about how the message was transmitted and processed by different mail servers.

AI Analysis

AI Analysis is performed only on the raw headers of the message and not on the message content.

AI Analysis helps you quickly assess whether a message is suspicious by reviewing its email headers and authentication results.

Watch this video or open the guided walkthrough to learn how to generate an AI summary of email headers.

Show me how to generate an AI summary of email headers

When you click AI Analysis in the Raw Header tab, you see an AI-generated summary of the email headers. It shows the results of authentication checks such as SPF, DKIM, and DMARC, and highlights issues including domain alignment issues, missing signatures, or failed policies. The summary also shows the overall authentication status of the message based on these results.

Instead of manually interpreting long and complex header values, you get a clear explanation of which checks passed or failed, and why the message may be risky.

AI Analysis makes it easier to identify spoofing attempts, forwarding issues, or configuration problems without needing deep email-header expertise.
