Overview
Inbox Zero, created by productivity expert Merlin Mann, is an email management approach emphasizing rapid decision-making and keeping your inbox empty (or nearly empty) by processing messages decisively rather than letting them accumulate.
Core Philosophy
Inbox is a to-do list others can write on. The goal isn't empty inbox for its own sake, but rather spending minimal time and attention on email.
The Five Actions
Every email gets one of five actions:
1. Delete (or Archive)
- Not needed
- No action required
- FYI only
- Get to zero
2. Delegate
- Someone else should handle
- Forward with clear request
- Remove from your plate
- Trust and empower others
3. Respond
- Quick reply needed
- Can do in <2 minutes
- Handle immediately
- Clear from inbox
4. Defer
- Needs action but not now
- Move to task list
- Schedule for later
- Set reminder
- Remove from inbox
5. Do
- Requires immediate action
- Can't delegate
- Time-sensitive
- Complete and archive
Process
Set Specific Times
- Check email 2-3 times daily
- Not first thing in morning
- Batch processing
- Close between sessions
Process to Zero
- Decide on each message
- Apply one of five actions
- Don't re-read later
- Touch once, decide once
Maintain System
