Once the e-mail is registered in the database of the storage unit and the specified distribution date and time has elapsed, the transmission unit of the mail distribution center reads the electronic mail from the database of the storage unit and transmits the electronic mail to the transmission destination address via the network. Therefore, the e-mail is not transmitted by the transmission unit of the mail distribution center until the distribution date and time, and is registered in the database of the storage unit of the mail distribution center. Thus, it is possible to cope with changes in the distribution date and time of the e-mail, the transmission destination address, the mail text, and the like, and the deletion of the e-mail itself.
