Listrak is another B2C marketing automation system that mostly does email for retailers. But its clients are mid-size businesses where the marketers are less likely to need or want a robot to build campaigns for them. Listrak is instead expanding to Facebook and Google advertising. Specifically, its new “audience automation platform” lets marketers automatically load leads captured in Facebook into Listrak and use Listrak lists as audiences for Facebook and Google AdWords campaigns. Nothing revolutionary here but it does eliminate some drudgery.
