We have an organization of 5k G suite users and are conducting a phishing campaign to test security awareness.
Using G Suite we have whitelisted domains and IP addresses for our phishing vendor and added them to our spam filter
When we run our campaigns many of our users are not recieving the emails as it appears that G Suite marks them as spam before email box arival.
We believe it may be the Google API flagging the emails,
Has anyone ever successfully done phishing tests and campaigns with large amounts of users using G Suite?
