Yes, because “bigstrat2003” said so. I work for a 1000+ consulting company and no one uses email for internal communications. Even for company wide messages leadership uses Slack.
Heck even when we first start a project we either federate (or whatever you call it) the client’s Slack workgroup with ours or we ask to be on their Teams channel.
Before working where I worked now, I worked for the 2nd largest employer in the US, even there most communication happened over Chime or Slack.
On a personal level you actually email personal contacts - in 2026?
I email my dad documents and photos I need printed (and he uses his work office's laser printer). I forward the billing statement I receive monthly from my family's ISP to my mom via email. And I'm "Gen Z"
