We may all be using instant messaging and texts these days but email is still important. Email is very important especially when you need to refer to something and have conversations with multiple people, without it vanishing in a conveyor belt of crap.
Two such email providers spring to mind for what I think, are the perfect solution. Fastmail and Protonmail. Protonmail offers a free account as well as paid plans. Fastmail offers only paid plans. Both, in my opinion offer a superb email experience.
