The entire Google account will be suspended unless there's payment. I'd have to audit everything my Google accounts are used for, find alternatives, train users on the N new services, and deal with all the migrations. Which frankly is impractical. Some stuff is not easily migrate-able (YouTube subs/history, Android purchases, ...), and unless I don't need a Google account again ever, I'll probably end up migrating to an @gmail one at least partially.
But at least I keep the domain?? Which I'd then be paying a mail provider about the same amount for. Plus probably more for any other paid services.
To say nothing of convincing and migrating my family/other users.
If I could only keep the Google account going with my own mail/services that'd be something. They say I "may" retain access to YouTube and Photos, for now. And the account will be in a 'suspended' state that requires payment to get out of.
It's not exactly a surprise, and I know "that's what I get" for using Google services. But it's still scummy.
I'm running through my head thinking of all the things in my domain account. Email archive/filters/rules, contacts, calendar, docs (mine and things shared with me), Drive, photos, Play purchases, Google One subscription for extra space, Android, Google Cloud.
Then I have stuff on a plain @gmail account that didn't work with my domain account - family library, links. That was already annoying. Don't want to mess that up either.
Should I merge the accounts or create a new @gmail account to hold everything?
My estimate is that it will take days of migration/backup/testing to move over, then extra time to ironing out issues that crop up. Hopefully I don't lose any content or purchases...
Even with email forwarding I believe I'll lose cosmetic things like using your domain as the owner of calendar invites, photo sharing, etc.
This is for 1 email account/domain only. I think I'll probably pay up.
So for my situation, I can just use IMAP to move the mail to a new provider. Easy peasy.
