When I look at my Apple Mail app, I see tons of mailboxes I've created over time. I have mailboxes for business activity, including About: Macs, and mailboxes for personal use. There are so many mailboxes that I think I may have gone a bit overboard in organizing, although some of you may believe that's not possible.

One mailbox I've created has been very helpful, and that's my Newsletter mailbox. Within this folder are all of the newsletters I subscribe to, sorted and stored. This makes it easy to find the newest newsletters. It also means I can go back in time and easily find older newsletters that may be of interest. It sure beats trying to search through one big Inbox to locate things.
