Introducing the inbox health score — and why it's a habit loop

Inbox zero is a bad metric. It measures emptiness, not health. You can hit zero by archiving everything important, and you can be perfectly on top of things with 4,000 archived newsletters sitting around.

The inbox health score measures what actually matters: are commitments slipping? It rewards few stale action items, no VIPs waiting on you, follow-ups under control, and noise contained. It drops when promises age unanswered.

The 0-100 number recalculates daily and lands in your morning brief. That cadence is deliberate — a score you see every morning becomes a habit loop. Yesterday 68, today 72, the +4 feels earned. Behavioral products from credit scores to fitness rings work this way for a reason.

No competitor ships anything like it, which we find strange — it is the single clearest answer to the question every busy person asks: am I on top of things or not?

Your score starts calculating with your first scan. Most users start in the 40s. Watching it climb is the point.
