The Very first message was sent over the ARPANET (The Advanced Research Projects Agency Network) Network in late 1971 by a programmer Ray Tomlinson to himself on another machine. The First message was "QWERTYUIOP". The text message is like so because he was trying to experiment to send the message. When he was successful in doing so he sent a message to the rest of his group explaining how to send messages over the network. The first use of network email announced its own existence.

"I sent a number of test messages to myself from one machine to the other". "The test messages were entirely forgettable. . Most likely the first message was QWERTYUIOP or something similar," he recalls now.

Ray Tomlinson was making improvements to the local inter-user mail program called SNDMSG. The experimental file transfer program called CPYNET could append material to a mailbox file just as readily as SNDMSG could. The missing piece was that the experimental CPYNET protocol had no provision for appending to a file; it could just send and receive files. He chose to append and at sign and the host name to the user's (login) name. The purpose of the at sign (in English) was to indicate a unit price (for example, 10 items @ $1.95). He used the at sign to indicate that the user was "at" some other host rather than being local. So @ symbol has sense. And This is the starting of First Email message. Mail was the form used in the original RFC. The service is referred to as mail and a single piece of electronic mail is called a message whereas eMail, capitalizing only the letter M, was common among ARPANET users. Network-based email was initially exchanged on the ARPANET in extensions to the File Transfer Protocol (FTP), but is now carried by the Simple Mail Transfer Protocol (SMTP), first published as Internet standard 10. "Tomlinson's email program brought about a complete revolution, fundamentally changing the way people communicate", the Internet Hall of Fame commented in its account of his work.

Tomlinson's Email messaging system was not considered important at first as its development was not a concern of his employer. He merely pursued it because it seemed a neat idea to him. "Don't tell anyone! This isn't what we're supposed to be working on", Tamlinson said to his colleaques while showing them.

He recieved many awards and honors such as George R Stibitz Computer Pioneer Award from the American Computer Museum in 2000, a lifetime achievement Webby Award from the International Academy of Digital Arts and Sciences in 2001 and many more.
