Would hosting your own be an option? You can get a VM in your cloud provider of choice for say 10 USD a month, then add a control panel such as hestia, ispconfig, mailcow (and many others), and then you have full control over your email. Add as many domains, email accounts as you like.

I should add that most of these options have installer scripts that take all the setup work out of the equation.

I am a software developer, so I guess I could have done it. That said, I'd rather not do it, spending my time on other things.
