That's the finer point that brings a lot of frustration. For example: We have a slack channel for every support case with our business. Whenever a case is closed, we archive that channel. Whenever a channel is archived, slackbot sends a direct message to every user in that channel so they will know it was archived. The message cannot be muted, and has the same notification authority as a direct message from a real person. This means that when someone is closing support cases while I am not working, my phone will alarm me that I got a direct message from a slack user; something that I generally need to know about. Slack has had an issue open regarding this for months, yet nothing has changed. If I had an open-source client, I would have fixed this problem myself as soon as I ran in to it.
