I'm not involved in the policy management, but my office uses Google account management. I also have to free trial one of the services I use, because my account got pwned in an attack long ago.

Turns out, my office gives us 6 different emails to choose from. Two different usernames (old, from 8 years ago, and the new one) as well as three website names (.net, .com, and another website).

Literal gold for 30-day trials.
