I am in the process of setting up some new nurture campaigns that I want live in 2015. In the past, I have used both drip campaigns and engagement engine campaigns.
I am wondering what most people prefer. My challenge is that new prospects are coming in through a variety of different angles (10-15 pieces of content bringing in leads), so i want them to receive future emails based on the content they did NOT already download. In this respect, a regular drip campaign seems to make more sense for me. However, I also like how the engagement engine prevents prospects from receiving emails they have already received, and this doesn't seem possible through a normal wait and send drip campaign.
Does anyone have any suggestions for what they use?
