Oh, didn’t read your question carefully as well. IDK, there is no viable alternative as of now. Asynchronous, federated messaging system that replicates messages to every host in the chain (you have it in sender’s client, on recipient server and on recipients devices, all of them, provided its IMAP). I don’t know, I really think it is wrong to speak about email as about particular tech. It is bunch of protocols and technologies that form a _concept_. It is hardly possible to replace the concept. If you change everything, but keep the way people interact with it you will get same email simply delivered through different protocols. Like Fido. Almost the same thing but through different protocols. I think we’d better off advocating for people to pay for their email services than change the concept of email itself.
