Google Workspace classic whitelisting

In this article, we’ll show you how to make sure that SoSafe’s simulated phishing emails will reach your users' inboxes. In addition, we will explain how you can prevent Google from showing a warning related to those emails.

All SoSafe-related information you will need to enter can be found in the Manager (Settings / Whitelisting).

If you need more detailed information, check out Google’s support article.

1. Log in at https://admin.google.com and select Apps, followed by Overview

3. Select Spam, phishing and malware to expand this section
4. Add the IPv4 addresses shown in the SoSafe Manager (see above) under SoSafe mail servers. Separate each address with a comma. Select Save to confirm.

Setting up spam filters

We need to prevent the simulated phishing emails from being classified as spam.

1. Navigate to the Spam, phishing and malware page on https://admin.google.com, as outlined above
2. Under Spam, select Edit and give your filter a name, e.g. SoSafe2
3. Make sure that Bypass spam filters for internal senders, Bypass spam filters for messages from addresses or domains in selected lists and Bypass spam filters and hide warnings for messages from senders or domains in selected lists are all checked
4. Select Create or edit list under Bypass spam filters for messages from senders or domains in selected lists add the SoSafe mail servers (as above) but also all email addresses listed under Envelope sender addresses (technical senders) on the same page. Make sure that Authentication required (received mail only) is disabled.
5. For the next section, called Bypass spam filters and hide warnings for messages from senders or domains in selected lists, you can select Use existing list
6. Select Save to confirm
