Despite aggressive content and reputation filtering, spam is still a major problem for ISPs, driving significant cost increases and customer churn.
Increasing Costs
Filtering always leaves a window of vulnerability, allowing spam to be sent unimpeded before botnets become blacklisted and new content rules are deployed. With each new spam outbreak, ISP costs rise. The dips in anti-spam effectiveness cause server loads to spike, message volumes and email delivery delays to peak, and a new round of help desk calls. The solution is often to purchase additional servers and frequently re-size infrastructure.
Customer Churn
Dealing with spam ineffectively creates problems for customers legitimate email is crowded out by spam processing, causing unexpected delays, and inboxes fill up with unwanted emails. Most customers are oblivious to the normal low level of spam but when they notice a sudden increase i.e. when new campaigns hit - they want action. And if they don't get it they often leave to find a service provider that gives them the protection they want. With the cost of acquiring new customers reaching approx. $150, losing them due to spam is never good news.
