I'm firmly Gen Z and love email. Messaging is great, but emails have a formality that is infuriating for casual conversation, but works really well for anything important or weighty.
True about "formality" - especially for me, I use long-form emails as documentation. Screenshots, links, backgrounds, explanations - that if required, I can then later paste into a document. While I was "always like this" (sorry not sorry), it firmed-up when I was required as a roving "field engineer" to prepare end-of-day detailed status reports when onsite with clients.
