Slack is really poorly built for async workflows though. That's why in my product I have all communication be async, and figure out who needs to get notifications (also async) from their role in the interaction. For example, if you're the owner of a story and someone asks a question you get notified, and the asker gets notified when you reply, but everyone else gets to keep their sanity. I also structure comments and require you tag them with the purpose of the comments so people know what it is up front (question, sugestion, todo, etc). That really keeps the stress levels down.
