For example, we subscribe to several e-mail newsletters that we don't need to read immediately. An Outlook rule automatically moves the e-mail newsletter into a Newsletter folder for reading at a later, more convenient time. Sometimes you can glance at the subject line to know you can hit delete. Other times you need a little more information. The preview pane integrated in Outlook 2000 allows you to quickly scan an e-mail without opening it and scroll by pressing the spacebar.
Efficiency experts recommend dealing with a piece of paper only once.
That also is good advice for managing e-mail. Once a message arrives, read it and act on it. Respond to it. Do not duplicate. Let others know your preferred means of communication.
