[nickpsecurity]

I've met quite a few and heard from even more IT guys that worked for them. I can at least add a few data points I've seen.

First is reason nothing goes away at most big companies: if it ain't broke, don't fix it. It's something they understand, they're often lay people who might not want to learn something else, they might have tons of stuff built on top of it (tech or processes), tons of important information stored in old emails (it's archive medium, too), and they'll get emails from other people anyway. So, why not keep using what you've been using.

A few others I hear occasionally on top of that big set. One that I like is that it's asynchronous. They can put emails off easier without it seeming like they're ignoring people. Managing it is fast and easy vs some web apps for communication. The security might be perceived as better esp with security software they likely have for email & data breaches they see on other things that aren't intranets or Gmail. It's decentralized, vendor-neutral protocol which existed for ages (stability). Bosses in smaller firms even use it straight-up as free alternative to paid chat or archive tools if it's Gmail. Just to avoid paying anyone past the ISP which is also cheap or someone's Wifi haha.

So, there's a few I've heard that tell me email ain't going anywhere.
