This Monday I had a series of calls with marketers evaluating campaign management solutions. After the economic slowdown I am starting to see a steady renewal of interest in marketing technologies. The questions ranged from: "How is campaign management different from marketing automation?" to "How much do the various modules cost to implement?" to "What's the on-demand market look like?". But by far the most commonly asked question was about the integration of outbound (batch) and inbound (real-time in the context of the interaction) marketing programs.
