How to View Email Headers in Gmail

Email headers contain important information about an e-mail such as routing, server IPs, Identity of the sender, subject, and tracking information. This data can be used to troubleshoot email problems, or to the origin.

If you report inappropriate messages to the authorities, you’ll need to paste the full header content.

  1. Open the email message in Gmail.
  2. Select the More downward-pointed arrowhead next to the Reply button in the top right corner for the message whose headers you want to see.
  3. Select Show original from the menu that comes up.
