In accordance with an embodiment, described herein is a system and method for providing a user messaging service for use with a cloud computing environment. In accordance with an embodiment, the system includes a notifier component, which receives information describing notifiable events that occur within the cloud environment during the provisioning of the enterprise applications, and communicates the information to a user messaging service at a user messaging server. The user messaging service is configured, according to one or more user communication preferences, to communicate to users, notifications describing the notifiable events, via one or more channels according to the preferences associated with the users. For example, a cloud account user can indicate a preference that status notifications for that user, such as completion of an operation or operational alerts, be communicated via one or more preferred channels, for example email, instant messaging, or social media.
