GTD for email: empty your inbox without doing everything

Getting Things Done (GTD), David Allen's method, starts from a simple idea: your head is for having ideas, not for holding them. Your inbox is the same. It is there to receive, not to remember. Applying GTD to email turns your inbox into a sorting station instead of a warehouse.

Empty doesn't mean done

David Allen says it in his email guide: an empty inbox doesn't mean all the work is done. It means you have decided what each message means, then put it in the right place. Read but not decided, an email stays in the inbox. You reread it, you re-evaluate it, it weighs on you.

GTD breaks work into five steps: capture, clarify, organise, reflect and engage. For email, capture is already done: everything lands in your inbox. The real work starts at the next step, when you take each message and ask: does this require an action from me?

It's the same logic as Inbox Zero: zero isn't a performance goal, it's the sign that every message has received a decision.

Five decisions for every email

Open an email and pick exactly one of these five outcomes. Delete: no action, no value. When in doubt, throw it out — Allen insists on the delete key. Archive: no action, but the information may be useful later; search will find it. Do it now: if the reply takes less than two minutes, do it. Rereading the email later would cost more than answering now.

Delegate: someone else is better placed; forward it, then keep track of what you're waiting for. Defer: the action takes more than two minutes; the email leaves the inbox and joins your action list.

According to Allen, in a busy inbox at least a third of emails can be handled in under two minutes. That is often where the inbox shrinks fastest.

Four folders are enough

No need to stack subfolders. Allen recommends a simple list and two clearly visible action folders at the top. In practice: @Action for emails that need more than two minutes. @Waiting For for what you expect from others (a reply, a document, an approval). Someday / Maybe for ideas without a date. Reference (or the archive) for everything else.

The @ prefix pushes action folders to the top of the list, apart from reference folders. That's GTD's golden rule: never mix what needs an action with what is just information. Otherwise your brain re-sorts everything at every glance.

The @Waiting For folder is your safety net: it's the one you review to follow up at the right time.

Making it last: the weekly review and time blocks

Filing isn't enough. An @Action folder nobody looks at becomes a second inbox, just better hidden. GTD includes a weekly review: once a week you go through @Action and @Waiting For, follow up, and delete what no longer makes sense.

Day to day, process email in batches at set times rather than at every notification. Batching and time blocking are GTD's natural allies.

GTD tells you how to sort; it doesn't tell you where to start. That's where Virtus Lever completes the method: each morning it surfaces the highest-leverage email — the idea behind the Domino method — tracks your follow-ups and measures your backlog. You keep the decisions; the tool keeps the memory.
