Disclosed herein is a framework for pushing service notifications to users via selected channels that are chosen based on user history. In accordance with one aspect, the framework determines if a notification is to be sent to a particular user. The framework may further determine if the notification requires an action. If the notification requires no action, the framework may choose, from multiple channels, a channel with lowest receive time duration. The framework may then send the notification via the chosen channel.
