Push Notification Delivery rates depend on the app type and frequency of usage. For example, in the graph below, the delivery rates for Shopping apps are higher than Telecom because they are used more frequently.

As the time between interactions on Push Notifications increases, Delivery Rates decrease. In the chart, 84% of customers did not receive Push Notifications because they did not click on the previous ones for 4 weeks.
Device and OEM
