"Empty inbox" isn't a good productivity metric — you can empty your inbox by handling only trivia. Useful measurement means tracking what reflects your real impact.
Vanity metrics
The number of emails processed flatters the ego but says nothing about value created. You can knock out fifty messages without moving forward on what matters.
Likewise, an ultra-short response time can hide unhealthy reactivity, where you sacrifice deep work to reply in ten seconds.
What's worth tracking
Track instead: daily time spent in email (bring it down), the backlog of undecided threads (keep it low) and response time on your high-stakes threads (shorten it).
These metrics tell a useful story: are you spending less time on email while handling the essentials better?
Measure to adjust
A metric is only useful if it changes a behaviour. If your email time is climbing, strengthen your time blocking or cut some noise.
A growing backlog often signals a decision problem, not a speed problem — revisit your priorities.
