Abstract: A database includes one or more physical location identifiers such as postal addresses, delivery or street addresses, or geographic coordinates. A correlator correlates electronic addresses with physical location identifiers. The correlated electronic addresses can incorporate part or all of the corresponding physical location identifier. The correlated electronic addresses can further incorporate a reference to an individual, such as a name or title, or a reference to a group of individuals, such as by name. Correlated electronic addresses allow reception of electronic communication. Services offered with electronic delivery of correspondence to correlated electronic addresses include return receipt, insured delivery, certified delivery, forwarding, non-delivery notification, and non-electronic delivery. Costs associated with operation of the electronic mail may be covered by administration of postage or when the recipient elects electronic delivery of correspondence traditionally delivered by paper mail.
