I use this technique in Slack by setting a reminder on a message so I can follow up later.
Sometimes I even push it to the next day or week by setting a reminder for 09:00. The only downside is that Slack doesn’t seem to have considered this workflow. Instead of giving me a single notification that several messages are ready for follow‑up, I get multiple push notifications on my phone. It’s a bit irritating, but it’s still the best option for now.
Came here to make exact comment. I can't let anything fall through the cracks at my job but I don't necessarily need to be the one handling.
Mondays I will typically have 30-50 of these waiting that sequentially get snoozed 3 hours, tomorrow, next week until resolved or first rights of refusal from others are exhausted and I handle myself :).
