The decision
Push notifications should provide timely value that the user expects. Define the reason for each message and let preferences reflect meaningful choices. Permission prompts are more understandable when they appear after the user sees what reminders will do.
In practice
A booking app can offer appointment reminders without sending promotional messages through the same setting. Explain the difference. Avoid treating a permission grant as unlimited permission to interrupt the user.
- Map message triggers, audience, frequency, quiet periods, and deep links.
- Test expired sessions, changed bookings, and duplicate triggers.
- Evaluate whether the reminder supports task completion alongside opt-outs and complaints.
When to take the next step
Plan preferences before adding promotional or operational messaging. Identify which notifications provide time-sensitive value and which should remain optional or appear inside the app.
