I am trying to target customers that purchased a product x days ago using advanced expression function but it is not working. This was fairly simple on Neolane but can't get it to work on ACS.
That isn't actually what I'm looking for. For example, last 7 days would bring an open window that looks back to everyone who did an activity in the last 7 days.
I want to build a drip campaign series that target people exactly 30 days after they made a purchase. Hope that clarifies.
