Some tips I follow to make my Inbox(0).
- Check email only at stipulated time.
- Setup Spam filters.
- Delete all unnecessary emails that escapes spam filter. Add the sender to Junk list.
- FYI emails are junked or filed according to its content.
- If an email ping-pong more than THREE times, I will pick up the phone or Skype. The person do not understand my writing.
- Use Reply. Only when absolutely necessary, Reply to all.
- Is that CC really necessary?
- Make email Subject to the point.
Instead of "Meeting", I would write "Project Discussion. Today, 4 pm. Meeting Room A."
