I love marketing articles that are seriously practical and helpful. Here's a link to a new one from Kristin Zhivago entitled, Justifying Marketing Automation Systems. It details out how much money you can expect to save from various types of marketing-related software and ASPs, and includes rules of thumb plus step-by-step instructions for you to figure out how much you'll save. I wish this article had come out before budgeting season, but hey beggars can't be choosers.
