To ensure that our phishing simulation emails are delivered successfully to your inbox and not marked as spam, you'll need to add our domain and IP address to the allowlist in your Google Workspace Admin Console.
Prerequisites
You will need an administrator role in the Google Workspace Admin Console to perform these steps.
Steps to Allowlist by Domain and IP Address
Log in to the Google Workspace Admin Console: Visit the Admin Console and log in with your administrator account.
Navigate to Gmail settings: From the left side panel, select "Apps". In the dropdown menu, select "Google Workspace" then "Gmail".
Access "Spam, Phishing, and Malware" settings: In the list of settings that appear, find and select "Spam, Phishing, and Malware".
Add Guardz IP to "Email allowlist": Scroll down to the "Email allowlist" section. Click on it, and in the field provided, add the Guardz phishing simulation IP address: "149.72.40.178". After entering, click "Save".
Configure "Inbound gateway": Scroll further to the "Inbound gateway" section. If it's not already enabled, click the "Enable" button. In the "Gateway IPs" list, add the same Guardz IP address: "149.72.40.178". Ensure that "Reject all mail not from gateway IPs" is unchecked. Click "Save".
Do NOT check "Reject all mail not from gateway IPs": This is crucial, as checking this box without specifying all existing gateway IPs, if any, could halt all email delivery. Therefore, leave it unchecked unless you are certain of your settings.
Disable Gmail spam evaluation for Guardz phishing simulation IP: Under "Message Tagging", check the box for "Message is considered spam if the following header regexp matches". In the "Regexp" field, enter some unique text value (e.g., "guardzsomeuniquestring"). Additionally, tick the box for "Disable Gmail spam evaluation on mail from this gateway; only use header value", which will now apply to the Guardz IP address. Click "Save".
Bypass spam filters for Guardz phishing simulation domain: Scroll to the "Spam" section and click "Configure", or "ADD ANOTHER RULE" if rules already exist. Check the box for "Bypass spam filters for messages from senders or domains in selected lists". Then, click "Create or edit list". In the address list, add "mailpercents.com", the domain used by Guardz. After creating the address list, go back and now select "Use existing list" and select the list you just created.
Save your settings: After making all the necessary changes, save your settings by clicking the "Save" button at the bottom of the page. Please note that it may take up to 24 hours for these changes to fully propagate throughout Google's systems.
