The hybrid mail concept has been growing in popularity over the past few years. The development of the concept can be attributed by changing needs of senders of hybrid mail documents and receivers of these documents. Providers of hybrid mail such as the UK Post office which runs UK Postbox, the Swiss Post Office which runs postbutler, the Australian Post Office which runs Hotsnail, and the U.S. Post Office which runs E-Snailer as well as leading couriers such as FedEx which runs FedEx Office have realized that people are opting for emails over traditional mail and they have developed hybrid mail to remain relevant and profitable.
Senders of hybrid mail have contributed to the development of the hybrid mail concept because they are looking for a way to save money on their mailing costs, they are more concerned about reducing their carbon footprint, and they are interested in reduced delivery time. Receivers of hybrid mail have contributed to the development of the concept because some of them do not have access to the Internet and they therefore need traditional mail in their mail boxes and because they want to get some documents in good time. The development of the concept can also be attributed to the extensive use of the computer and Internet-enabled hand-held devices such as PDAs and cell phones.
