For an email that you've received in Gmail, you can see where the email came from by looking at its headers, including how it got from the sender to your organisation’s mail servers. When it comes to spam and phishing, you may be requested to provide email headers to your IT or Information Security Management department for investigation.


How to:


  1. In Gmail, select or open a message.

  2. In the top right, tap the three dots and then click “Show original”.

  3. The headers will appear in a new tab. From here, you can obtain the full message header by clicking “Download original”. 

  4. Use the paperclip icon to attach the downloaded file to an email.
