What is a Push Notification?

A push notification is defined as a message sent by an app to inform or engage users. This type of notification appears on a user's device even when they are not actively using the app, thereby providing real-time updates or information that can prompt user interaction. Push notifications are commonly used to alert users about new content, reminders, special offers, or important updates, making them a vital tool for maintaining user engagement and communication.

In contrast, marketing emails, system alerts, and in-app messages have different functions and delivery mechanisms. Marketing emails are generally sent through email platforms rather than through app notifications, making them distinct from push notifications. System alerts are related to device settings and functionalities, such as software updates or battery warnings, focusing on the device's operational state rather than app engagement. In-app messages are presented while a user is actively using the app, serving a different purpose from push notifications that reach users regardless of their app activity. This distinction helps clarify the specific role of push notifications in mobile communication strategies.
