Retention via Notifications
Thoughtful, behavior‑based notifications keep users engaged long after they close your Mini App. Done right, they lift retention and even earn you a coveted home‑screen badge in World App.
1 · Why They Matter
| Benefit | Details |
|---|---|
| Retention boost | Targeted pushes can 2–3× day‑7 retention. |
| Free visibility | ≥ 15 % open rate unlocks a persistent badge on your app icon. |
| Strict standards | < 10 % open = delivery paused for 7 days—quality is non‑negotiable. |
2 · Quality Thresholds
| Open‑Rate (7‑day) | Platform Action | Your Next Step |
|---|---|---|
| < 10% | Paused for 1 week | Audit triggers & copy immediately |
| 10%+ | Badge displayed | Maintain & iterate |
| 25%+ | “Excellent” tier | Scale what works, test new ideas |
3 · Core Principles
- Trigger‑based > Broadcasts – React to user actions (wins, risks) instead of fixed schedules.
- Personalize – Use
