Ideally, you should never require email ever again: not for resetting passwords, not for communicating with friends, not for receiving bought tickets, not for sharing photos, not for receiving advertising or scams . E-Mail is old technology, as @moon9river has pointed out, and it is just not the right tool for the job for anything I can think of.
Unfortunately it can be difficult at times to get rid of old technology (anyone still using fax at work like I have to?).
Privacy and E-mail is an inherent contradiction. Do your research if you don’t believe me. PGP is a nice, but to be honest a failed attempt at adding privacy emails, for many reasons. Don’t bother. My recommendation? Use a messenger. Whatever your friends are using, be it Signal, Threema, Jitsi.org Whatsapp, Telegram, iMessage, Element (formerly Riot), XMPP with Omemo… All of them have their advantages and disadvantages and none of these are perfect, but at least for some usecases they are the right tool for the job.
Signal wins for me on privacy and trustworthiness, Threema wins for me for their business model pushing their technology to business scenes, Jitsi wins for hosting online meetings, Whatsapp wins for for bringing End-to-End encryption to the masses (note though: you are giving your address book away for free to Facebook, every day), Telegram has not convinced me in any way, but seems to be quite popular among some kind of people, iMessage wins for Apple fanboys…
The perfect tool doesn’t exist yet. E-Mail has shown that a federated decentralized system is great in a way. But this feature hinders innovation. That’s why E-Mail will never be fixed. Modern tools are not interoperable. Maybe some day in the future they will be, but it’s unlikely… We’ll just have to learn this important skill: choose your tool wisely for the job you need it.
