haven’t looked closely at any of these but they all seem to promise the core demand generation capabilities of email, landing pages, automated nurturing, lead scoring, and sales system integration. The question this raises in my mind is where the industry goes from here. The more sophisticated vendors will of course continue to add features, but it’s not clear that most marketers will be interested in the additional capabilities or be able to handle the added complexity. Well, I wouldn’t ask the question if I weren’t leading up to something.
