I have a self-hosted domain too, with docker-mailserver, but only for less important email. For important communications I really worry about ending up on a spam list somewhere and landing directly in people's spam box, plus there are potential downtime concerns, so I stick to GSuite for that.

I've had a couple occasions where things have disappeared into the void. This was, of course, after moving away from a static IP (thanks Sonic). On the inbound side, I've had repeated delivery problems with Sonic blackholing mail from some financial institutions.

Otherwise I've had pretty good luck.
