An engagement studio program is created with an Email Send action step immediately followed by an Email Open trigger step with a 3 day wait. A prospect is sent the email and progresses to the Email Open trigger. On day 2, the prospect opens the email.
How would the prospect progress through the trigger step?
The Pardot prospect audit capabilities can list all the data that was obtained by Pardot and how the data changes as the prospect interact with your emails, website, and CRM sync.
