Email entered limited use in the 1960s, but users could only send to users of the same computer, and some early email systems required the author and the recipient to both be online simultaneously, similar to instant messaging.
The service is simply referred to as mail, and a single piece of electronic mail is called a message. An Internet email consists of an envelope and content; the content consists of a header and a body. == Origin == Computer-based mail and messaging became possible with the advent of time-sharing computers in the early 1960s, and informal methods of using shared files to pass messages were soon expanded into the first mail systems.
Many US universities were part of the ARPANET (created in the late 1960s), which aimed at software portability between its systems.
An email message sent in the early 1970s is similar to a basic email sent today.
For example, several writers in the early 1970s used the term to refer to fax document transmission.
Ray Tomlinson is credited as the inventor of email; in 1971, he developed the first system able to send mail between users on different hosts across the ARPANET, using the @ sign to link the user name with a destination server.
In 1971 the first ARPANET network email was sent, introducing the now-familiar address syntax with the '@' symbol designating the user's system address.
International email, with internationalized email addresses using UTF-8, is standardized but not widely adopted. The history of modern Internet email services reaches back to the early ARPANET, with standards for encoding email messages published as early as 1973 (RFC 561).
As a result, finding its first use is difficult with the specific meaning it has today. The term electronic mail has been in use with its current meaning since at least 1975, and variations of the shorter E-mail have been in use since at least 1979: email is now the common form, and recommended by style guides.

The Simple Mail Transfer Protocol (SMTP) protocol was introduced in 1981. For a time in the late 1980s and early 1990s, it seemed likely that either a proprietary commercial system or the X.400 email system, part of the Government Open Systems Interconnection Profile (GOSIP), would predominate.

Published in 1982, RFC 822 was based on the earlier RFC 733 for the ARPANET. Internet email messages consist of two sections, 'header' and 'body'.

RFC 5322 replaced the earlier RFC 2822 in 2008, then RFC 2822 in 2001 replaced RFC 822 – the standard for Internet email for decades.
The low cost of sending such email meant that, by 2003, up to 30% of total email traffic was spam, and was threatening the usefulness of email as a practical tool.
The US CAN-SPAM Act of 2003 and similar laws elsewhere had some impact, and a number of effective anti-spam techniques now largely mitigate the impact of spam by filtering or rejecting it for most users, but the volume sent is still very high—and increasingly consists not of advertisements for products, but malicious content or links.

For example, in comparison to 75% of those consumers in the US who used it, only 17% in India did. ====Declining use among young people==== , the number of Americans visiting email web sites had fallen 6 percent after peaking in November 2009.
A sponsored 2010 study on workplace communication found 83% of U.S.
While in the earliest years of email, users could only access email on desktop computers, in the 2010s, it is possible for users to check their email when they are away from home, whether they are across town or across the world.
Technology writer Matt Richtel said in The New York Times that email was like the VCR, vinyl records and film cameras—no longer cool and something older people do. A 2015 survey of Android users showed that persons 13 to 24 used messaging apps 3.5 times as much as those over 45, and were far less likely to use email. ==Issues== ===Attachment size limitation=== Email messages may have one or more attachments, which are additional files that are appended to the email.
In September 2017, for example, the proportion of spam to legitimate email rose to 59.56%. ===Malware=== A range of malicious email types exist.
