Does anybody remember Eudora? Not the Thunderbird version, the one before that. It was fast as hell with cool shortcuts (eg Alt-clicking on from groups all the emails from that sender) and therefore super easy to find stuff and organize your email even if you had way too much of it. My M1 MBP is probably 2000x faster than last computer I had running Eudora, but modern email is still slower and clunkier. A web based email service that is blazing fast and makes sorting/filtering/searching my email easy is something I would be happy to pay for.

Another email service I want would be one that I have to authorize the sender before their mail gets into my inbox even if it's not classified as spam. Sure, that email can be routed to some dumping ground so I can sift through it if an expected message is missing, but by default nothing goes to my inbox unless I've routed the sender there. And when I "accept" a sender it should be trivially easy to route them to any mailbox or make a new one. And it should be trivial to manage those routing rules later. All this is already possible with existing services, but enough of a pain that I don't maintain it.

The last thing is a tough one: a way to port my existing email into the system and a guarantee that I won't lose my email if you shut down in a few years. Trying other email providers is not worth it if I won't be able to find anything from the past and I might be at risk of losing them in the future.
