I prefer Slack over email... coming from using Outlook for 20+ years in a corporate environment, slack is light years beyond email in rich communication. I'm trying to think of 1 single thing email does better than slack in a corporate communication. Is slack perfect? Absolutely not. I don't care that I can't use any client I want or any back end administration costs or hurdles. As a user, there is no comparison.
I can think of a few: - Long form discussion where people think before responding. - Greater ability to filter/tag/prioritize incoming messages. - Responses are usually expected within hours, not minutes. - Email does not have a status indicator that broadcasts whether I am sitting at my desk at that particular moment to every coworker at my company.
#2 I agree with you, again Slack is not perfect but better than email [my opinion]
#4 Slack has status updates, email does not. So you can choose to turn this off, again boundaries.
