I initially liked this solution but I don’t think it’ll work for me. There seems to be a hard limit on the number of emails. It also seems like you can only share the domain with your apple family (my extended family isn’t part of my apple family sharing plan.)

I assume by "hard limit on the number of emails" you mean daily sending limits, which is quite high for a personal user (500 per day)? If that's the case, Gmail also seems to have a similar limit.

Or do you mean there's a hard limit on total number of emails you can store?

Sorry for the confusing wording, I meant email accounts. It looks like you can only share the domain in your apple family sharing plan which means only 6 different accounts.
