Northern Trail Outfitters (NTO) imports a file daily into Marketing Cloud of customers who have bought a tent from their website that day. They want to set up a month-long welcome Journey which sends emails specific to the purchase such as the type of tent, the available accessories for the tent, and care of the tent at different points throughout the Journey. NTO also recognizes that due to their competitive prices, they have had customers purchase more than one tent within a month.
What type of data should be used in the Decision Splits in their Journey to make sure the choices reflect the correct tent?
