Descriptive email folder name

An e-mail folder should not be so narrow of purpose that it’s never used, but neither should it be so broad that it becomes overstuffed with messages, unless you use that folder strictly for archiving and don’t need to refer to its contents regularly. Use a descriptive name for each folder and keep it short enough that it doesn’t require scrolling within the Mail Folders pane. Remember that folders can usually be nested, too.
