A fifth mistake you can make with mobile app notifications is to stick to the same old formats and methods, and miss out on the opportunities to stand out and delight your users. Mobile app notifications are not just text messages or alerts, they are a way to create memorable and immersive experiences for your users. To avoid this, you should explore and experiment with different types of notifications, such as rich media, interactive, or dynamic notifications, and use them to deliver value-added content, features, or offers. You should also leverage the latest technologies and trends, such as AI, AR, or voice, to make your notifications more smart, personalized, and conversational.
