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.

The correct logic would be to select recipients based on product and package criteria and then check whether there is an absence of tracking logs for opens, indicating that the email was not opened. The expression "Tracking Logs (trackingLog): do not exist" serves this purpose by filtering out all recipients who have an open event in their tracking logs for the specified delivery.References:This explanation is derived from the standard practice of tracking recipient interactions in email marketing campaigns, where tracking logs are used to determine opens, clicks, and other recipient actions.
