AAM and Push or In-App Notifications from Adobe Mobile Services

You can target push and in-app messages to mobile users that are in Analytics segments or custom segments. However, Audience Manager segments aren't available for push or in-app messaging at the time of writing this article.

Push messages are sent using pre-existing Adobe Analytics segments or custom segments that may be created on historic Analytics data already collected.

In-app messages are triggered from Analytics data already tracked by the SDK.
