I'm not sure the 'like email' thing helps.
Email is confusing and not what most people use to connect with others. I don't know anyone who met via email.
Trying to get groups of people to connect meaningfully over email didn't work. Messenger apps did work as they removed user freedom to top-reply and break everything.
I'm vaguely interested in IT, seflhost a little and compile a kernel from time to time but email still seems esoteric and confusing to me.
Join the fediverse! It's as simple as setting up an email server!
