We have to disagree about the purpose here.<p>For me mail is for async, coherent exchanges. IM is not a replacement: It is usually a conversation, usually short and short-lived and synchronous.<p>Async doesn&#x27;t have to imply that I don&#x27;t get a notification about your mail. It just means that I probably won&#x27;t answer right away - or at least on my time.<p>Anyway: Mail plus ~instant~ notification is a thing for me and I don&#x27;t want to give that up.
