Invented by Ray Tomlinson, email first entered limited use in the 1960s and by the mid-1970s had taken the form now recognized as email.

In 1967 he joined the technology company of Bolt, Beranek and Newman (now BBN Technologies), where he helped develop the TENEX operating system including the ARPANET Network Control Program, implementations of Telnet, and implementations on the self-replicating programs Creeper and Reaper.
In 1971, Ray Tomlinson, of BBN sent the first network e-mail.

Its original iteration was designed to move between DEC PDP-10 mainframe computers running the TENEX operating system using the ARPANET, with a later version by Ray Tomlinson designed to copy itself between computers rather than simply move.

SNDMSG

Tomlinson was asked to change a program called SNDMSG, which sent messages to other users of a time-sharing computer, to run on TENEX.
It allowed all users of the machine to send a simple form of email to each other, but it was extended by Ray Tomlinson in 1971 to allow sending to users on other computers accessible over the ARPANET, addressing them by appending the other system's host name after an "@" sign.
