Explanation
To append an Urchin Tracking Module (UTM) variable string to links in emails, NTO should use Web Analytics Connector. Web Analytics Connector is a feature that allows NTO to append UTM variables or other custom parameters to the links in their emails. Web Analytics Connector can be configured at the account, business unit, or send level, and can support up to four parameters per link. The other options are incorrect because:
Advertising Studio. This is a product that allows NTO to create and manage advertising campaigns across various channels, such as Facebook, Google, or Twitter. However, this product does not allow NTO to append UTM variables to links in emails; it only allows NTO to use their Marketing Cloud data for audience segmentation and targeting.
Personalization Builder. This is a product that allows NTO to create and deliver personalized content and recommendations to their subscribers based on their behavior and preferences. However, this product does not allow NTO to append UTM variables to links in emails; it only allows NTO to use predictive intelligence and machine learning to optimize their content and offers.
Web and Mobile Analytics. This is a product that allows NTO to collect and analyze web and mobile data from their subscribers, such as page views, visits, conversions, and revenue. However, this product does not allow NTO to append UTM variables to links in emails; it only allows NTO to use web tracking code and mobile SDKs to capture and report on their web and mobile activity.
