An advertiser needs to see campaign performance week over week and wants to receive an email with this report each Monday. Which action should the advertiser take to make this happen?

Building a custom report and setting the report frequency to weekly is the most efficient solution. Pinterest Ads allows users to create custom reports with specific metrics and dimensions, and then schedule these reports to be delivered via email at a chosen frequency, such as weekly. This automates the process, ensuring the advertiser receives the desired data regularly without manual intervention. Manually downloading reports each week (options A and B) is time-consuming and prone to human error. While saving metrics in the reporting dashboard (option D) is useful for quick viewing, it doesn't automate email delivery of the report.
