Systems and methods for defining, observing and detecting triggering user account events that initiate a user account alert message to be sent to one or more users are disclosed. Location and merchant, transaction result, device and, usage history/trend types of user account alerts and trigger criteria can be defined or selected by users, issuers were notification alert engines. Alternatively, user account alerts and trigger criteria can be defined by analyzing previously observed user account events, such as credit card transactions, to determine user profiles and user account usage trends, i.e. credit card spending patterns, as baselines for comparing newly observed user account events. If information associated with the newly observed user account events match any of the trigger criteria or are inconsistent with the determined user profile or user account usage trends, then user account alerts can be sent to one or more users.
