At this point I'd be more than willing to pay a monthly for Google services if it meant I knew I'd get prompt support if something went wrong. I've looked into getting a GSuite account but from my reading like there are some incompatibilities with services that I use on the free tier.
I already use Google's paid-tier for their storage and I use their domain registrar.
I get that I'm using a free product so that means they have to do customer service on the cheap. I get it. I'm happy to give something that's mission-critical in my life mission-critical payment without the pain of migrating to a new email provider.
Shut up and take my money, Google.
