What Is an Inbox Health Score?
Your Inbox Health Score is a 0-100 metric that measures how well-managed your email inbox is. Think of it like a fitness score for your digital life. A high score means your inbox is organized, responsive, and under control. A low score means you're drowning.
The score is calculated from multiple factors, each weighted based on its impact on your productivity and email hygiene.
The Scoring Factors
Unread Ratio (25% of score) What percentage of your inbox is unread? A healthy inbox has less than 10% unread emails. More than 50% unread is a critical problem.

Score Benchmarks
- 90-100: Elite. Your inbox is a well-oiled machine.
- 70-89: Good. You're managing well with room for optimization.
- 50-69: Average. You're keeping up but spending too much time on it.
- 30-49: Below average. Email is consuming too much of your day.
- 0-29: Critical. Your inbox needs immediate intervention.
Tracking Progress
Check your score weekly and track the trend over time. A rising score means your systems are working. A falling score means something has changed — maybe a new subscription flood, a busy period where cleanup was neglected, or a rule that needs updating.
The goal isn't perfection — it's consistent improvement. Move your score up 5-10 points per month, and within a quarter you'll have a fundamentally different relationship with your inbox.
