How can an interested lead that comes to Lenoxsoft's website and fills out the Contact Us form receive a follow-up email each time he or she submits?

Form or Form Handler? I want to integrate with a third-party system.

Lenoxsoft is interested in folding up with IT professionalthat are actively engine with their marking materials.

An engagement studio program is created with an Email Send action step immediately followed by an Email Open trigger step witha 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?

An administrator wants to create a dynamic list of all prospects who have accessed a certain file have a specific value, but there are moreprospects than anticipated in the preview.
What could be happening?
