Which tool would Northern Trail Outfitters use to automate the exporting of engagement data for all sends into their data warehouse?

The correct approach for Northern Trail Outfitters to automate the exporting of engagement data into their data warehouse would be utilizing Tracking data extracts within Automation Studio. This option allows for the automation of data extraction processes without manual intervention, making it efficient for handling large volumes of data continuously.

Automation Studio is specifically designed to create and manage automated workflows, which can include running tracking data extracts at predefined intervals. By setting this up, Northern Trail Outfitters can ensure that engagement data from their email sends is regularly exported and delivered to their data warehouse for further analysis and reporting.

In contrast, schedule reports configured within Tracking and scheduling the "Email tracking" report within Reports would require manual oversight and are less efficient for regular or bulk data extraction. SQL Query exports of the _engagement data view, while powerful for custom queries and more tailored data output, do not automate the process in the same way as the dedicated tracking data extracts. This makes Tracking data extracts the best choice for the needs of Northern Trail Outfitters.
