Earlier quoted context omitted.
Not just youth - I work with teams of all ages (skewing towards older GenX - and even younger boomers), and getting them to commit to sending an actual email versus an instant message is incredibly difficult. But - I was "raised" with email and have personal archives going back 30+ years now. It was also my "CMS", and it "just worked" with everything and everyone across every platform.
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.
