  • Statistics about Spam

    Larger ISPs such as America Online report that anywhere from one-third to two-thirds of their email server capacity is consumed by spam. Because this cost is imposed without the consent of either the site owners or the authorized users, many argue that email spamming is a form of theft of services.

    In May 2004, it was reported more than 80% of all emails in the United States were spam.

  • 10 billion spam emails are sent every day;
  • 30 billion are expected by 2005;
  • 150 spammers send 90% of all email;
  • 37% of US email is spam; 8% of UK emails;
  • EU businesses spend .10 billion euros each year to deal with spam.
