Honestly i'd love to migrate off of google, but its been a pain. My family is a heavy user of google calendar so I either have to migrate them off or I have to keep my google calendar account.

I tried fastmail but honestly its not as easy to use as gmail.

Has anyone pulled off a migration like this? how did you do it?

My family uses google calendar but has never used gmail for day to day stuff.

Maybe a problem if you send calendar invites, I guess?

Obviously, can't close your account and still use their calendar, but whatcha gonna do.

You can have a google account using a not-gmail email.
