To enable ContactMonkey to easily count the recipients in your Google Groups you will need to coordinate with your Account Manager and a member of your IT to set up a utility account for ContactMonkey internally.
For this to work:
- your organization must have admin SDK enabled
- your team must provide an account with https://www.googleapis.com/auth/admin.directory.group.readonly and https://www.googleapis.com/auth/admin.directory.group.member.readonly permissions.
This count will only be accurate for flat lists/groups, it will not work with nested groups or lists.
