A vehicle email notification method and system that uses customer-selected severity settings to send special notifications to the subscriber. The notification system uses triggers to initiate the generation and transmission of email messages that provide diverse types of dynamic vehicle information to the subscriber. The email notifications are triggered by different events, some of which are independent of the vehicle (e.g., a monthly trigger), and others of which occur at the vehicle, such as a mileage or low oil life trigger. The notification system builds and sends to the subscriber an email message that contains the dynamic vehicle information along with a diagnostic result indicative of the severity level of a vehicle condition. That diagnostic result is compared to a customer-supplied severity setting to determine whether additional contact with the subscriber is needed. This allows the subscriber to receive special notification when a more severe condition exists.
