Trying to set up an email campaign that will send to a contact if they have filled out a form more than 7 days prior and it will be on going. Is there certain criteria for "in past before" to show up?
Sure, setup a batch with the correct smart list as
Filled out Form in past before 7 days
Not Filled Out Form in past 7 days
Filled Out Form in Past X days
I have a similar program. We have a wait step built into the flow. The smart list is "filled out X form" and the first step in the flow is a Wait step. Wait > Duration = X Days. Hope this will work for you too.
