Which tool provides a tab showing message subscriptions and stats for a single user?

The User Profile provides a dedicated view for individual users within the Braze platform. It allows you to examine various aspects of a user's engagement and interactions with your app. In the context of message subscriptions and statistics, the User Profile specifically includes a tab that details the messages this particular user has subscribed to and the corresponding metrics related to those subscriptions. This feature is essential for understanding the user's behavior and ensuring personalized communication.

Other options like the Segment Dashboard, Message Center, and Campaign Overview focus on broader analytics, campaigns, or on aggregating user data rather than providing in-depth insights at the individual user level. The User Profile's capabilities in this regard make it the correct choice for accessing message subscription stats for a single user.
