more than one-third of all email is spam
According to ZDNet, more than one-third--36%--of all email traffic is spam, and the proportion is likely to increase by the end of the year.
Once considered a productivity-enhancing tool, sorting through e-mail has become daily drudgery as employees separate wanted messages from heaps of spam. Market research firm Gartner estimates that a company of 10,000 employees suffers more than $13 million worth of lost productivity because of internally generated spam. Add the Internet, and the problem gets much worse.
"A year, year-and-a-half ago, spam was an annoyance; now it's a productivity drain," said Maurene Carson Grey, research director for e-mail and messaging at Gartner. "A lot of the spam has become quite distasteful, and it's a drain...not just on bandwidth, but on storage."
