Ensuring that phishing simulations and human risk training emails reach your users without being blocked is essential for an effective security awareness program. Google Workspace's built-in security features can sometimes filter these emails as spam or phishing attempts. To prevent this, you need to whitelist the designated IP addresses for the Human Risk Module.
This guide will walk you through the process of whitelisting these IPs in Google Workspace step by step.
By adding these IPs to your Google Workspace allowlist, you ensure:
Phishing simulations are delivered to employees for training purposes.
Human risk training emails reach inboxes without being marked as spam.
Security awareness programs function without interference from email filtering.
Go to admin.google.com.
Sign in using your administrator credentials.
Click on Apps.
Select Google Workspace.
Choose Gmail.
Scroll down and select Spam, phishing, and malware.
Locate the Email allowlist section.

198.21.6.191
168.245.56.242

By implementing these whitelisting rules, you ensure that security awareness training emails and phishing simulations are effectively delivered to your users, allowing them to build stronger cybersecurity habits without interference from spam filters.
