Push notification marketing is frequently used to promote discounts, deals, and new products. In general, creating the feature of push notification marketing can be quite complicated. A common use case is that once an app receives a push notification and a user taps it, the app will bring up the product page directly or a promotion section within this app. It will take quite an effort to establish features like this. However, we also have seen a use case like this: The user’s device received a push notification; the user opens the app and then sees a promotion page. This page acts like a flyer and has content similar to “Check out our new products.” Or “10% off for X’mas.” Since the flyer page is an overlay on top of the main app, it can be dismissed with a tap. In this chapter, I will show you how to implement this behavior by using Parse’s easy-to-use push notification feature.
