I am designing a nurture program where we send email 1 for content/offer 1 and if the person does not click on the offer, then in 2 weeks we send them new email 1a with the same offer. If they did click, they would move on to get email 2 with offer 2 next. Can this be set up in the engagement module or do we need to use Nurture campaigns with Traffic Cop, etc? If it's the latter, I can't find any instructional documentation to show me how to do this.
