Tracking open rates shows how many users found the notification interesting enough to tap. Click-through rates reveal whether the content motivated action, while conversion rates indicate if users completed the intended goal, such as making a purchase or signing up. Monitoring engagement after the click helps determine whether the experience matched user expectations. Opt-out rates and notification disables can highlight messaging that feels excessive or irrelevant. Retention and re-engagement metrics show whether notifications bring users back over time. Analyzing these patterns helps refine timing, content, and targeting strategies.
