I use proton's email service with a domain that I own. The client works good enough for me. It has filters, multiple addresses going to one box. There are probably some more advanced features that I don't use and proton and doesn't have. I have a legacy gmail account that I am going to keep alive. All email is forwarded from that gmail account to my proton box.
