A multi-channel message exchange system selects a service provider that is best suited to deliver each individual message for customers of the message exchange system. The message exchange system selects a service provider based on customer criteria provided by the customer, data structures provided by the service providers, quality scores describing performance of the service providers, channels used by the service providers to deliver messages, or any suitable combination thereof. The message exchange system may select the service provider that provides the best combination of quality of service, value, and delivery channel given the customer's specific needs. The data structures may geographic jurisdictions in which the service provider provides message delivery, channels through which the service provider is willing to deliver messages, or any suitable combination thereof.
