Benefits

1. User Engagement and Retention
   Both web and iOS push notifications help engage users with customized content periodically, or when the user hasn’t visited the application in a while. You can also integrate action elements into the notifications so the user can interact with your application directly in the notification panel without having to visit the application. You can send promotional messages about the latest offers, updates, and things happening in your business, and interactive content that grabs the user’s attention or makes them visit the application.
   
   Push notifications in both web and mobile applications allow you to deliver messages instantly to a large audience. This helps you keep in touch with your users and retain them for your business. They create an effective communication channel with your users and guarantee the constant availability of your service to them.

2. Unlimited Push Notifications
   There are also no restrictions on the number of messages that you can send to the users of your application from Catalyst’s end. For iOS apps, the standards for the limit to the number of push notifications that you can send is set by Apple.
   
   For web applications, the standards vary with each push service or browser. However, most browsers do not impose heavy limits on push notifications, and this enables you to use Catalyst’s service to fit your business needs.

3. High Throughput Delivery
   Catalyst ensures a high delivery rate of push notifications that keeps pace with the throughput of the notifications that you send from the application.
   
   Catalyst servers are fast and are capable of instantly delivering your push messages to the intended push service workers for web push notifications, and APNs servers for iOS push notifications. You can experience lag-free and instantaneous delivery of push messages from your application.

4. Auto Scaling
   Catalyst servers are equipped with an auto-scaling feature that allocates required resources to your application whenever the load increases. The resources are scaled up or down instantly based on the throughput of the push messages received for your application.
   
   Auto-scaling supports even a large number of push messages that you send and ensures consistency in your app’s performance. This also eliminates failures in delivering the notifications due to heavy loads.

5. Delivery through a Single API Request
   You can use Catalyst APIs to enable push notifications for a particular user’s device for the web or iOS app, when the user grants permission. You can also send push notifications to an unrestricted number of user devices using a single API request. With this easy publishing functionality, you can save time and effort while sending periodical scheduled push notifications, or notifications that are sent as required.

6. Easy Implementation
   Catalyst helps you in automating the task of sending push notifications and makes managing your application a lot easier. For example, for manual push notifications, you can incorporate a pop-up box or something similar in the admin access of your application, for your app’s admins to type in and send push notifications to target users manually.

For scheduled or automatic push notifications, you can use Catalyst APIs to retrieve the list of target devices from the Catalyst Data Store or elsewhere, and send push messages to all of them with a single API call.
