I turned off notifications at the top level except @mentions, and then specifically turned back on just the super important channels (operations type stuff). I even explicitly mute a lot of channels that don't need my daily input, and people know that they need to @mention me if they need attention in that channel. And making sure to put the right quiet hours, and time zone in to shut them all down.
