Amazon Pinpoint is a targeted push notification service for mobile apps. It allows marketers to segment users and send targeted push notifications from the console. Developers can also integrate the mobile SDK to enable features like silent notifications and custom attributes. Pinpoint scales to deliver millions of messages quickly and reliably. It has a generous free tier and pay-as-you-go pricing model based on the number of messages, events, and monthly targeted users. The service is currently available in US East (N. Virginia) with plans to expand to other regions internationally. To get started, users can integrate Pinpoint with their mobile app from the AWS Mobile Hub console.
