1. Junk. I recommend using Gmail, as it has the best spam filter possible. I get zero spam in my inbox. That’s a huge improvement over my previous accounts at Yahoo and Hotmail, where I’d have to tediously mark dozens of emails as spam.

2. Notifications. I often get notifications from the many online services I use, from Amazon to WordPress to PayPal and many more. As soon as I notice those types of notifications filling up my inbox, I create a filter (or “rule” if you use Mail.app or Outlook) that will automatically put these into a folder and mark them as read, or trash them, as appropriate. So for my PayPal notifications, I can always go and check on them in my “payments” folder if I like, but they never clutter my inbox.

3. Batch work. I get certain emails throughout the day that require quick action (like 10-15 seconds each). As I know these emails pretty well, I created filters that send them into a “batch” folder to be processed once a day. Takes a couple minutes to process the whole folder, and I don’t have to see them in my inbox.

4. Stupid joke emails.

5. Publish policies.

6. Have an external to-do system.

7. Process quickly.

8. Be liberal with the delete key.

9. Short but powerful replies.

10. Process to done.
