Inbox zero: Merlin Mann's five exits for any inbox
by Andreas Tissen · · updated
A forwarded mail says the ticket prices for the workshop went up. It belongs to the workshop budget, as a next action, but the budget lives in another app, so the mail stays where it is. A week later it is still in the inbox, and you have read its subject line a dozen times on the way to other things.
Inbox zero was written for exactly that pile. Below is what Merlin Mann proposed, the step where it usually fails, and how it looks when the inbox and the places items go to are branches of the same outline.
Five ways out
Mann wrote a series called Inbox Zero on his site 43 Folders in 2006 and gave a Google Tech Talk on it on 23 July 2007. For him the zero was about attention: how much of it stays stuck in the inbox. The inbox is where things are sorted, and nothing should live there.
He gave each item five possible actions: delete, delegate, respond, defer, do. Delete (or archive) what needs nothing. Delegate what someone else should do, and note that you are waiting for it. Respond when a short answer finishes it. Defer what needs real work by moving it to where that work lives, with a date if it has one. Do it now if it takes less than two minutes, the limit David Allen uses in Getting Things Done, with one condition worth knowing.
None of the five actions mentions mail, so they work on a paper tray or a notes app just as well.
Defer and delegate are where it stalls
Both send the item somewhere else, and that somewhere is usually another program. Take the ticket prices again. If the inbox is your mail and the workshop project is in a task app, deferring means opening the task app, finding the project, typing the action and archiving the mail. Delegating means the same again with a Waiting for list kept in a third place.
So the cheap exits get used and the expensive ones do not. The inbox turns into a second, worse project list, and the deferred items are the ones that vanish, because they now exist in two places and you trust neither. When the destinations sit next to the inbox, a deferral is one move and the text you captured is the text that arrives. Removing that copying is all an outline adds.
The inbox as a branch
Pando is the outliner I build. It runs in the browser and on the phone, everything in it is a bullet that can hold other bullets, and Claude can read and write in it over MCP, the standard Claude uses to connect to outside tools. Here the inbox is one branch, the doors are another, and Waiting for is a third.
The doors in the picture follow the Inbox Zero template, which renames two of Mann's actions. A short reply counts as Do. Anything that needs real work goes through Decide, where it is rewritten as a next action and moved under its project, which is what Mann's defer did; the template's Defer is for items that cannot move before a certain day, so they get that date. Ticking a door does not move anything. The ticks only show which doors this sweep has used, and when the Inbox is empty you untick all five.
The ticket prices leave through Decide: the bullet is dragged under the workshop project and reworded as "update the budget for the new ticket prices". A bullet can also have its own email address, so forwarded mail lands in this Inbox next to your own captures.
When Claude writes into it
My own Pando inbox fills from two sides. I put things there, and Claude, connected to my outline, files a checkbox there whenever a piece of work is waiting on me, with a note on why. That is the inbox pattern, and the same doors apply to what Claude files: you answer under the item, you do it and tick it, or you move it to a project.
Claude can also prepare the sweep. The template's agent prompt lets it suggest a project for each capture and draft a next action as a child bullet, overnight if you like, and forbids it to tick a door or delete a capture. In the morning you make the decisions with the drafts in front of you.
Pando is free up to 5,000 bullets, and Pro with no limit costs 3 EUR a month. To run one inbox for your own captures and for what Claude needs from you, create a free account and connect Claude.
