To be clear, push notifications are messages that pop up on a mobile device. They look like SMS text messages and mobile alerts, but they only go out to users who have installed your app. Push notifications differ from in-app messages in that the user sees push notifications even if your app isn't open on their device (they typically pop up on the user's lock screen), while users only see in-app messages once they open your app.
Why use them in your app? For a couple of reasons. If you're a developer looking to sell your apps, push notifications give you a chance to communicate directly with your customers. Let them know about special features in your app, upcoming events, or new products and thank them for choosing your app. Or if you're part of a development team or you're using the app in a company setting and you need to send and receive messages from other team members or other people in the company, push notifications can handle that too.
So, what do the notifications sent to customers or other users look like? Web push notifications normally include these elements:
- Title (such as your company or app name).
- Message (brief text).
- An icon, emoji, or image (often used to supplement the message).
- A Call To Action (such as a clickable link or button).
