Probably the strange link at the bottom of the comment, linking to the site we are talking about.

Especially because you can always mute Slack or use do not disturb as well.

But can Slack help you rethink team communication, or redefine the way teams move work forward, together? I know I want a messaging tool that delivers results.

I have no connection of any sort to Stride (or any chat app for that matter, other than a few I use, which doesn't include Stride yet). This aspect of chat has just been a point for me for years. Looks like Stride and Twistapp are both attempting to solve it, among others. Wouldn't surprise me if there were some Slack plugins to do similar things as well.
