Hybrid mail
Hybrid mail is mail that is delivered using a combination of electronic and physical delivery. Usually, it involves digital data being transformed into physical letter items at distributed print centres located as close as possible to the final delivery addresses. An e-mail letter (also L-mail and letter mail) is a letter which is sent as an email using a computer, then printed out and delivered as a traditional (physical) letter. It is a communication means between the cyber and the material world. The printer or mail transfer agent prints the electronic mail on paper, the mail transport agent packs it into an envelope and the mail delivery agent or postman delivers it to the receiver's mailbox.
