Be aware that if you are using G Suite Legacy, whitelisting capabilities are limited and you may not be able to properly whitelist KnowBe4.

How to Whitelist by Email Header in Google Workspace
The below instructions will show you how to whitelist KnowBe4's simulated phishing emails and training notifications by email header in your Google Workspace (formerly G Suite) environment. This article reflects our most up-to-date best practices for whitelisting with your provider. Please be aware that your mail service provider may make changes to how their systems analyze our emails at any time. If you are having issues whitelisting using the procedure below, please contact our support team and they will be happy to assist you.
This setting is only recommended if you have a cloud-based spam filter in front of Google Workspace. If you are using Google Workspace for your mail without an additional spam filter, you can instead whitelist by IP address using this tutorial. Remember, you will also need to whitelist KnowBe4's IP addresses or hostnames in your cloud-based spam filter to make sure emails are delivered successfully.
We recommend setting up a test phishing campaign for yourself or a small group after you follow the below steps to ensure your whitelisting was successful. The setting may take up to an hour to propagate to all users so wait at least an hour before testing.
