How do I check the headers/raw source of an email?

Being able to check the raw headers of an email can be incredibly useful when troubleshooting. Headers contain all sorts of details about a message's security, composition, and even the journey it takes from point A to point B.

Our Support agents may sometimes ask you to give us the raw source or headers of an email to help them solve email issues. Below are a few methods for obtaining headers in some popular mail clients.


Gmail raw headers


Thunderbird raw headers


Outlook raw headers


Look for the option called "View Raw Message" under the More menu (displayed as 3 dots).
