And to be honest Email is ok. Email is like writing a letter and it should be.

You write it, think about it send it.

In a chat you just type and send as you think and decoding that stuff in hindsight is more work.

I’d rather get one focused and well thought out mail than 20.messages of which a quarter shouldn’t even bother me.

There is no real reason why you couldn’t write Slack messages as well composed as an email. But nearly nobody does.

Slack and Teams are different. Slack has muting. Teams does not.

I'll note that we never actually acted on this plan. The idea came up when we were comparing the two. The designated Microsoft Guy at the office was pushing Teams, because it's free as in beer. However, the inability to mute or leave a channel was a big 'wtf' and I'm honestly shocked that two years later they still haven't fixed it. It was a show-stopper for us back then and still would be now.

Why wouldn't you just Hide a Team you aren't interested in? I've hidden most of the Teams in our organisation because they aren't relevant to me.

Teams has mute on channels

On individual channels it does, on an entire team it doesn't. You can mention a team itself (rather than a channel in that team) and there's no way to mute that afaik.

I guess not all CEOs know what muting a channel means.
