Overwriting the Return-Path Header on Your Phishing Tests

The below steps will show you how to overwrite the return-path header on your KnowBe4 account. It is vital to do this if you're using a mail provider like Google Workspace (formerly G Suite), which will display "via KnowBe4" next to the sender address in your phishing tests if you do not.

If you're not using Google Workspace and not experiencing issues with "via KnowBe4" next to your incoming phishing test emails, leave the return-path header as-is.

1. Log in to your KnowBe4 admin account.
2. Click your email address on the top-right of the screen, then click Account Settings.
3. Navigate to the Phishing Settings section.
4. Under the Phishing Email Headers subsection, click the checkbox next to Overwrite Fixed Return-path Address with Sender Address.
   
5. Save your settings by clicking Save Changes at the bottom of the page.
