You can bypass Google Workspace's spam filters by applying a content compliance rule to our IP addresses. This rule will allow our simulated phishing emails to be delivered to your user's inboxes. The Content Compliance whitelisting method involves two steps in Google Workspace: adding KnowBe4's IP addresses to the Email Whitelist, and enabling whitelisting by Content Compliance.
Content compliance is an alternative method to whitelisting by IP address in our Whitelisting by IP Address in Google Workspace article. We recommend using the content compliance method if you have an existing inbound gateway to use the content compliance rule or if you are unable to configure the inbound gateway.
This method of whitelisting is a two-part process. To navigate to the steps for each part of the process, click the jump links below.
- Add KnowBe4's IP Addresses to Your Google Workspace Whitelist
- Enable Whitelisting by Content Compliance
Add KnowBe4's IP Addresses to Your Google Workspace Whitelist
First, you’ll need to add KnowBe4’s IP addresses to your IP allow list for Google Workspace. Once you add KnowBe4’s IP addresses to your IP allow list, you can enable whitelisting by content compliance.
To add KnowBe4’s IP addresses to your Google Workspace whitelist, follow the steps below:
- Log in to the Google Admin portal and click Apps.
- Click Google Workspace.
- Click Gmail.
- Click Spam, Phishing and Malware.
- Under the Organizational Unit section, highlight your domain. Do not select a sub-organizational unit (OU).
Note: Google Workspace does not allow whitelisting by IP address for individual OUs. You can only whitelist by the entire domain.
- In the Email whitelist section, enter our IP addresses. Make sure to separate each IP address with a comma. For a current list of our IP addresses, see the IP Addresses, Hostnames, and Header Information section of our Whitelisting by Content Compliance in Google Workspace article.
