My email is still the free/legacy version of Gsuite, from before it was called Gsuite and it was just a way to have your own domain but serviced by Gmail. It's kind of a pain, because it's both not really a Google account, but also not a real Gsuite setup, and Google keeps quietly removing features from the legacy version of Gsuite. (You used to be able to use an external SMTP server to send as a different domain, but Google removed the UI to configure that in the free version) I've been really hesitant to upgrade to modern Gsuite, because I'm worried about upgrading and having something go wrong in the process - Google support doesn't have the greatest reputation.
