The exponential growth of email in recent years has tremendous impact on the growing numbers of workers who use computers. This year, Americans will send and receive well over 6.8 trillion email messages - approximately 2.2 billion messages each day - compared with just 293 million pieces of first class mail. The average office worker will send and receive between 60 and 200 e-mail messages each day. Microsoft, for example, processes more than 3 million email messages every day.

As a result, employees spend more time sorting through their email. Workers polled this year by the Gartner Group spent an average 30 to 35 percent more time working with e-mail than they did a year ago. Workers who must manage this ever-growing electronic content are at the most risk of being clogged up and bogged down with e-mail management.

Email usage has become embedded in the fabric of nearly every enterprise. The dependence on Email has increased to the point where enterprises find it difficult to operate without it. It is estimated that the compound annual growth rate (CAGR) business enterprise Email use will be 40%. If we assume that enterprise users are 20% of all Email users in 2000 and 25% of all users by 2005, then message volume for enterprise users will grow from about 5.2 billion messages per day in 2000 to over 28 billion messages per day in 2005 at 65 messages per day per worker. It is estimated, that, two-thirds of American workers use Email daily. The Email volume growth is causing problems with servers, computer networks and increasing demands on employees' time.
