Abstract: Usage information is determined that describes usage of different services by a user device. A combined usage of the different services utilized by the user device is determined and compared to monitoring criteria. When the monitoring criteria are satisfied, an electronic message is sent to an address associated with the user device.

Abstract: Usage information is received that describes usage of communication services by a communications device. The usage information is compared to monitoring criteria. When the monitoring criteria are satisfied, an electronic notification message is sent to the communications device before an additional charge is incurred.

Abstract: Data communications between devices are selectively blocked and resurrected based on error notifications. Data communications from one or more source devices to one or more intended destination devices are selectively blocked based on content of the data communications. The blocked data communications are stored in a database. A blocked data communication is retrieved from the database in response to an error notification from one of the source devices and/or from one of the destination devices. The retrieved data communication is then sent to the intended destination device.

When the monitoring criteria is satisfied, an electronic notification message is sent to the communications device. The electronic notification message when a communications service is initiated and before an additional charge for the communications service is incurred.

Abstract: Monitoring criteria is received that corresponds to a usage quantity for a plurality of services. Each of the plurality of services is provided over ones of a plurality of different communication systems. Actual service usage information is received for the plurality of services. The actual service usage information and the monitoring criteria are compared. An electronic notification message is sent when the monitoring criteria for one or more of the plurality of services is satisfied.

Abstract: An electronic mail/messaging system is operated by compiling information associated with an attachment for an electronic mail at a source. The information includes initial information and descriptive information. The initial information is sent to a destination. A determination is made whether the destination has a file that matches the attachment based on the initial information. The attachment is sent to the destination if the destination does not have the file. The descriptive information is sent to the destination if the destination has the file. A determination is made whether the file matches the attachment based on the descriptive information. The attachment is sent to the destination if the file does not match the attachment based on the descriptive information.

Abstract: Services accounts are managed by defining budget categories for the services accounts. Budgets are defined for the respective categories and rules are defined for the budget categories. Input on usage of the services is electronically received and the budgets are electronically adjusted based on the received input and the defined rules.
