How to reach inbox zero using the four D's system

Executive overview

Most people carry hundreds of unread emails, missing messages and losing trust. The fix is a simple triage habit borrowed from how you handle physical mail.

Apply the four D's to every email: delete, delegate, deal with, or drag to a folder. Run this once or twice a day. Inbox ends at zero.

The four D's

  • Delete — junk, irrelevant, no action needed
  • Delegate — forward to the right person
  • Deal with — read and respond immediately
  • Drag to a folder — defer to the right time slot

Deferral folders and when to use them

  • End of day — only open after 4pm
  • End of week — only open Thursday or Friday
  • Casual reading — review once a quarter
  • Follow up — reminder to re-contact someone later
  • Project folders — store already-processed emails by topic

How to run the system

  • Triage email once or twice a day, not continuously
  • An assistant can do the triage pass on your behalf
  • Process every item in the inbox before closing; target is zero
  • Scale applies: Starbucks executives handling 300–600 emails daily use this system
