How do you manage notification overload from email, Slack & GitHub?

I have been obsessed with this problem. As developers, we constantly switch between email, Slack, and GitHub notifications. I tracked mine: 47 app switches per day, about 25 minutes wasted on context switching alone.

I started building a solution called HeyRobyn — a native Mac app that puts all three in one window (SwiftUI, not Electron, all data on-device). But I am curious:

• How do YOU manage notification overload?
• Do you use any unified inbox tools?
• Would you actually want email + Slack + GitHub in one app, or does separation help you focus?

Genuinely want to hear different perspectives.
