Which data view would you use to view the subscription history for SMS sends?

• A. _SMSMessageTracking data view
• B. _SocialNetworkImpressions data view
• C. _SMSSubscriptionLog data view
• D. _PublicationSubscriber data view

Answer: (C)

To view the history of a subscriber’s SMS enrollment, use the SMSSubscriptionLog data view. This view is specifically designed to capture subscription events for the SMS channel—when a subscriber subscribes, unsubscribes, or has changes to their opt-in status—along with timestamps. That historical record lets you see how a subscriber’s SMS subscription status evolved over time.

In contrast, SMSMessageTracking tracks per-message events like sent, delivered, or failed, which shows message delivery details rather than subscription history. The SocialNetworkImpressions view relates to social media engagement, not SMS, and PublicationSubscriber deals with publication-related subscriptions, not SMS enrollment. So the SMSSubscriptionLog is the appropriate source for SMS subscription history.
