Email Deliverability Challenged By Increase in Spam Levels
Today Google owned Postini reported that worldwide spam levels had returned to levels not previously seen since before the shutdown of the McColo web hosting service 4 months ago. After the shutdown of McColo spam levels fell nearly 70%. Spam volumes have been steadily increasing this year by about 1.2% per day. The new technology employed by spammers appears to be a peer to peer spambot network that doesn’t rely on central nodes like those deployed at the McColo data center. Spammers are also using a new location-based technique to lure users to websites with news headlines and video based on local events. When the user clicks on the video their computer is infected with a virus.
Needless to say a new spam threat and an increase in spam levels will cause ISPs to double and triple their efforts to combat these mail messages from making it into their users inboxes. This will continue to challenge your ability to get your legitimate email into these same inboxes. Email delivery of legitimate marketing email and transactional email messages will require a much more intelligent and adaptable technology to maintain and protect IP address reputation and adjust to changes in ISP delivery rules.
In a previous post we unveiled a new IP tagging and warm-up feature. This is the first of several new features we are rolling out over the next several weeks that will enable the next generation of intelligent email delivery to improve email deliverability. More on these new features to come.
