I was very happy to stumble upon a blog post over on the BrightCarbon site called "Marketing Automation—A Failure". Of course, I am not happy to hear of anyone's failure, but I am happy to finally see someone talking about the marketing automation mountain so publicly.
Everyday, I hear from marketers that their top priority is to "really dig in and get our marketing automation fully working". That's usually followed by "...once I do that, I can focus on X, Y, and Z". Where X, Y, and Z are big business priorities (increase customer acquisition, decrease cost per lead, generate more leads, generate more online sales, etc, etc).
