Inbox zero is about the inbox, not the mail
by Andreas Tissen · · updated
Inbox zero was never about having no email. Merlin Mann's point, in 2007, was the time your attention is in the inbox. That is the number he wanted at zero. Nineteen years of productivity bloggers attached the phrase to the wrong noun, and so people delete mail at midnight, feel virtuous, and start tomorrow with the same forty open loops.
The useful version is a rule rather than a score: nothing stays in the inbox. Beauty has nothing to do with it. An inbox is a place things pass through, and anything that lingers there is a decision you are paying rent on.
Five doors out and no sixth

Every item leaves by one of five doors. The whole discipline is that there is no sixth.
- Do it, if it takes under two minutes. The rule is old and it holds.
- Decide it: give it a next action and file it under its project.
- Delegate it: move it under Waiting for, with the date you asked.
- Defer it: put a date on it, so it comes back on its own.
- Delete it.
People skip the second door, and it is the important one. "Reply to the tiler" is not an item you can act on. "Find last year's invoice, then reply to the tiler with the number" is. An inbox full of unclarified captures feels like work because clarifying is the work, and it is being deferred one item at a time.
Why the inbox belongs in the same tree as everything else
All five doors lead somewhere: to a project, to Waiting for, to a date. If the inbox lives in one app and the destinations live in another, every door costs a copy-paste, and a door that costs a copy-paste is a door people stop using. That is how an inbox becomes a graveyard.
In one outline every door is a drag or a keystroke, so emptying the inbox takes exactly as long as the decisions take. That is the honest floor. Usually it is about six minutes.
Your inbox also has an email address here, so a forwarded mail and the thought you had on the bus land in the same list, and they leave through the same five doors.
The agent's half
An agent reading your inbox at night cannot decide what matters. It should not try. What it can do is the sorting nobody enjoys: propose which project each capture belongs under, draft the obvious next actions, and flag the captures that have sat unclarified for a week. You open an inbox that is already grouped, and the six minutes go on deciding.
Take the five doors
Open the Inbox Zero template, press "Show in my Pando", and the inbox and its five doors land in your tree. Run it once, tonight, on whatever is already in your head.
