Abstract: In a preferred embodiment, the objective is to give an e-commerce system user control over when a message is sent so that it arrives at a time that is relative to a subscriber's local time zone. This gives users the ability to send messages to subscribers so that they are received by subscribers at a specific time of day in their time zone. For example, localized time zone delivery would send messages so that they are arrive in the inbox of subscriber “A” located in San Diego around 10:00 AM Pacific Time and around 10:00 AM Eastern Time for subscriber “B” who is located in Boston. Furthermore, localized time zone delivery allows system users to assign a time zone preference value to subscribers in their e-commerce system account.
