Another reason to throw on the pile of needing to setup a new domain to self-host email on, properly planned with 'alias per login' etc.

I'm not sure if the pile is big enough yet to make me do it, but it's getting there.

I might have to have two domains, one for critical communications and logins (banking, finances, tax, etc) and another for all those bullshit web sign ups. Ironically, it's the critical one I'd have to setup 9n a centralised SaaS (and therefore prone to such shenanigans as Google is proposing) in order to make sure communications don't get lost. Having said that, my current Google-hosted domain is free, and so it's likely been used for advertising and AI training already.
