Northern Trail Outfitters wants to provide its marketing team with a deeper understanding of email...

The appropriate solution is a Lightning Report based on the Marketing Performance Semantic Data Model . Salesforce's marketing reporting architecture provides semantic-model-backed report types that combine message-definition and engagement information into a unified reporting layer. The Marketing Performance Semantic Model specifically contains information about message send definitions and engagement data, allowing marketers to create detailed custom analytics instead of being limited to predefined dashboards.

This is important because unsubscribe information and unsuccessful message delivery are engagement-level events rather than ordinary Campaign Member attributes. A Campaign Member-based custom report therefore lacks the complete messaging and engagement model required for this analysis. Marketing Insights for Agentforce Sales is also designed for sales-oriented marketing intelligence and isn't the custom reporting mechanism requested here.

The uploaded source identifies option B as the answer. Salesforce documentation confirms that the Marketing Performance Semantic Model contains send-definition and engagement data and is available for custom analytics reporting.
