The history of mail or messaging services extends messages from one place to another, starting with the invention of writing. The first documented use of the postal system occurred in Egypt around 2400 BCE when Faros used officials to send instructions throughout the empire. The same type of courier service may have been used in the Fertile Crescent (500-220 BCE), the Han Dynasty in China (306 BCE) - 221 CE), the Islamic State (622-1923) CE) in Arabia, the Inca empire in Peru (1250-1550 CE), and the Mughal empire in India (1650-1857 CE). Learners must be aware of the postal services, generally used to send letter/posts manually through government postal department. This may take long time or few days to deliver the post.
Nowadays, mailing services to send and receive the text, photo, etc have been changed into electronic mail. Electronic mail is a technique of exchanging messages between people using electronic gadgets. It was founded by Ray Tomlinson in 1972 named as email or e-mail. It works on all computer networks which is called Internet. Sending this electronic post distance between the sender and receiver does not matter. Earlier email programs required the sender and recipient to both be online at the same time for instant messaging. Today’s advanced email servers need not be online at the same time. These servers are quite able to send, receive and store the messages. Users or their computers need not be online at the same time; they need to connect briefly, usually to a mail server or web interface as long as it takes sending or receiving messages or downloading them. Even today’s mobile device has made it very easy to send and receive the mail anytime, anywhere.
