Slack also has a scheduled send option. Just schedule it for the morning if its unimportant. Then there's no implied expectation of when something should be addressed.

I, like others, sometimes use work laptop for pleasure. actually, I know a lot of people who do this exclusively. sure, you can blame it on them... but also I use slack for more than just work, and when I see unread notifications, even if I didn't get a push, i'm compelled to read them.
