Do you use slack? You seem to be criticising the thing that slack is really good at. The postpone workflow is to switch alerts off, can be done on schedule for when you are not at work and manually for meetings etc. And it allows you to fine tune these between channels and people etc. There are a number of statuses that show to your co-workers (on holiday, sleeping, in meeting, dnd etc). Those messages are there unread for you to come back to when you are ready.
