Why push notifications matter
Push reaches the lock screen instantly, which suits genuinely time-sensitive news: the restock, the price drop, the order out for delivery.
The same immediacy makes it the fastest channel to burn: permissions are revoked in one tap and rarely granted twice.
What push is used for in ecommerce
- Back-in-stock and price-drop alerts the shopper requested
- Order and delivery status updates
- Time-boxed sales for opted-in audiences
- Cart reminders, sparingly
Questions
When should the permission prompt appear?
After a reason exists: on a restock signup or order placement, framed by what they’ll get. The browser prompt on arrival gets blocked by reflex, permanently.
Web push or app push?
Web push covers stores without an app and works on supported browsers; app push is richer for stores whose customers installed one. Either way, the discipline is the same: only what the subscriber signed up for.
