Marketing automation is happening. If you're looking at me now, you're ahead of the pack and potentially even your competition. I'm a career marketer with a knack for sales and building teams. We're both probably too busy for small talk, so let's get right to it and plot the course. I can't climb the mountain for you but the view from the top, and the resulting ROI, makes it very much worth the trip.
Pardot is the easiest to learn and then execute. Will take your team the least amount of time to provide managed email marketing & automation services to your client. Naturally you'll want to bill fixed rates.
