Explanation
Adobe Campaign allows you to create queries that filter recipients based on various criteria, such as their profile attributes, delivery properties and tracking logs. You can use queries to segment your audience and target specific groups of recipients for your campaigns2.
To achieve the requirement of sending a follow-up email delivery to those customers who did not open the previous delivery labeled "New Offers", you need to create a query that filters recipients based on their product, package, delivery label and tracking logs. You need to use the Tracking Logs (trackingLog) dimension and check if it does not exist for each recipient. This means that there is no tracking information for opening or clicking on links in the previous delivery3.
