Nucleus Research announced that the spam epidemic is costing US businesses $712 per employee each year in lost worker productivity.
As a result, users are spending 16 seconds identifying and deleting each spam e-mail, which translates into an annual cost of $70 bln to all US businesses.
Looking at the total e-mail traffic, Nucleus estimates that at least 90% of e-mail reaching corporate servers is spam. The average user receives 21 spam messages to their inbox each day. Many e-mail filtering technologies block anything with the word Nigeria in the title or text.
