I've been using it for about a year now and couldn't imagine trying to run a large E-mail system without it now.

Connection Management

Slowing down spam traffic can lead to dramatic improvements

Traffic Control™ slows down suspicious email senders, letting legitimate email through while causing impatient spammers to give up. Because spammers require rapid, high-volume delivery to make money, they disconnect after being slowed, looking elsewhere for unprotected targets. This is a completely different and more effective way to stop spam than other so-called traffic-shaping systems, which merely ask suspicious senders to retry later.

Traffic Control uses sophisticated analytics working at the network edge to separate legitimate senders from suspicious senders, ensuring resource availability for legitimate senders while punishing spammers. Numerous "Triggers" embedded in Traffic Control monitor sender behavior, reputation, and message content. Depending on which triggers fire, the sender is allocated a variable proportion of email server resources. Legitimate senders receive more resources than suspicious senders, who must wait to be served. Advanced users with specific requirements can write new triggers using a flexible Application Programming Interface (API).

Spammers are Impatient

More than 90% of spammers give up within 10 seconds

MailChannels has conducted extensive research into the behavior of spammers and legitimate email senders. One of our key discoveries has been that spammers are considerably less tolerant of delays in email delivery than legitimate senders. On analyzing millions of message delivery attempts across our customer sites, we have actually determined that the median spammer waits just five seconds to get a message delivered, whereas more than 60% of legitimate senders wait more than six minutes.

Spammers are dramatically less patient than legitimate email senders. This chart was generated using data from over 1.2 million email delivery attempts at a service provider customer of ours. The chart shows the median number of seconds for which senders in each group are willing to wait to get a message delivered.

The Connection Management technology built in to Traffic Control™ allows us to slow to down email connections coming from spammers so that they give up on message delivery. Real-world experience has proven that this technique works effectively to mitigate spam traffic.
