Make one of five decisions for every email
Delete, delegate, respond (two minutes or less), defer (to a task system), or do it now — never leave an email just "read."
Key takeaways
- What it is: Delete, delegate, respond (two minutes or less), defer (to a task system), or do it now — never leave an email just "read."
- Why it works: Leaving an email "read but unprocessed" in the inbox maintains it as an open loop in working memory — the Zeigarnik effect suggests that incomplete tasks continue to occupy cognitive resources until they are either completed or deliberately deferred to a trusted system. A five-option decision tree forces closure: the inbox item either leaves or gets parked in a system that will surface it at the right time.
- Evidence: Plausible mechanism, limited direct outcome data.
- Avoid: Creating a "to deal with later" folder that functions as a second inbox — this exports the problem without resolving it.
Why it works
Leaving an email "read but unprocessed" in the inbox maintains it as an open loop in working memory — the Zeigarnik effect suggests that incomplete tasks continue to occupy cognitive resources until they are either completed or deliberately deferred to a trusted system. A five-option decision tree forces closure: the inbox item either leaves or gets parked in a system that will surface it at the right time.
How to do it
- 1Delete or archive: if you don’t need to act or refer back, it goes immediately.
- 2Delegate: if someone else should handle it, forward it with a clear request and archive the original.
- 3Respond now: if a reply takes under two minutes, send it immediately and archive.
- 4Defer: if it requires more time, drag it to a task system (not a "follow-up" folder) with a due date.
- 5Do: if it is a short task you can complete right now, do it and archive.
What the evidence says
MechanisticThe two-minute rule (act immediately on sub-two-minute tasks) is a practitioner heuristic from Getting Things Done; the five-decision framework is practitioner advice. The underlying open-loop mechanism has support from Zeigarnik-effect research on cognitive load.
Honest caveat: The five-decision specific structure is Merlin Mann’s practitioner framework; it is not directly tested in research. The open-loop mechanism it addresses is well studied.

Common mistake
Creating a "to deal with later" folder that functions as a second inbox — this exports the problem without resolving it.
