Push Notifications and In-App Messaging

iOS requires explicit user permission before any push notifications can be sent, while Android 13 and later also require opt-in. Average opt-in rates for iOS apps range from 40 to 60 percent across categories, with utility apps achieving higher rates than entertainment apps.

Request notification permission at a moment of demonstrated value within the app rather than at first launch. A pre-permission prompt explaining the specific benefit of notifications before the native dialog appears can lift opt-in rates by 30 to 50 percent compared to immediate permission requests.

Transactional push notifications are triggered by specific user actions or events: order confirmations, delivery updates, payment receipts, or booking confirmations. Users have high tolerance for transactional notifications because they provide clear, immediate value related to something the user actively initiated.

Behavioral push notifications respond to in-app activity patterns: re-engagement nudges for inactive users, milestone celebration messages, or reminders to complete an interrupted task. Promotional push notifications broadcast offers to segments of users and require the most careful targeting to avoid being dismissed as spam.
