The ease of managing multiple domain names in gsuite has made this an integral part, as now we are able to use it without having another tool such us Office 365 Mailbox or Gmail Apps available at your disposal! We can't really comment much about how easy its setup/use since I set up my first one over 3 years ago but looking back then there were more options than what you see today (as far as i know). Some features may seem basic like bulk-delete option which doesn;t feel intuitive enough when compared with other services out there - maybe something could be done? It's free so if nothing else helps keep using them until they add additional paid service offerings down the road! We mainly need 1) ability 2) visibility into our email address management process & history across accounts3.) control4.).
