Do you know that only 5% of all emails are delivered to our mailboxes? The remaining 95% is being identified as spam and blocked by server providers. This study was conducted by ENISA (European Network and Information Security Agency). In the survey ENISA analyzed the traffic seen by 90 service providers in 30 countries. It said that efforts to take on spam varied country to country, as did the amount of money being invested in solving this problem. Anti-spam budget vary from over 15,000 dollars for small companies to millions of dollars for the larger corporations. Nowadays, all anti-spam prevention measures (blacklists, greylists, etc) are quite effective, which made this problem manageable, making it a standard part of operations. And what interesting is that instead of looking at spam as a problem, most server providers view spam prevention as a key selling point that can provide a competitive advantage.
