# In-App Messaging

Legacy In-App Messages are banner messages delivered through push notifications that appear in-app when the user opens the application.

Legacy [in-app messages](https://www.airship.com/docs/guides/messaging/messages/content/app/in-app-messages/) are delivered through push messages and automatically converted to In-App Automation (IAA) banners for display. You can customize how these messages are converted using extender blocks on the legacy in-app message manager.

> **Note:** This page covers **legacy In-App Messages** delivered via push notifications. For In-App Automation (IAA) and Scenes, which are separate features with different triggers and capabilities, see [In-App Experiences](https://www.airship.com/docs/developer/sdk-integration/apple/in-app-experiences/getting-started/).


For general In-App Automation styling options, see [In-App Automation](https://www.airship.com/docs/developer/sdk-integration/apple/in-app-experiences/in-app-automation/).
