Set up a Typology Rule.
Configure the query 'Recipient delivery logs exist such as Event Date for Recipient delivery logs on or after 14 days before'.
Then, in the Delivery Properties in a Delivery, apply the new typology before execution.
Great Michele, you have the mechanics exactly right. What if we want to apply this restriction only to Recipients who got the Renewal e-mail in their Inbox. Can you (or someone else) think of how we would make the Filtering expression more specific to meet these additional criteria?
