Short for electronic mail, e-mail or email is information stored on a computer that is exchanged between two users over telecommunications. The first e-mail was sent by Ray Tomlinson in 1971
Email is a service which allows us to send the message in electronic mode over the internet. It offers an efficient, inexpensive and real time mean of distributing information among people.
E-Mail Address
Each user of email is assigned a unique name for his email account. This name is known as E-mail address. Different users can send and receive messages according to the e-mail address.
E-mail is generally of the form username@domainname. For example, webmaster@tutorialspoint.com is an e-mail address where webmaster is username and tutorialspoint.com is domain name.
The username and the domain name are separated by @ (at) symbol.
E-mail addresses are not case sensitive.
Spaces are not allowed in e-mail address.
The following rules make an e-mail address valid:
The username cannot be longer than 64 characters long, and the domain name cannot be longer than 254 characters.
There should be only one @ sign in an e-mail address.
The space and special characters: ( ) , : ; < > \ [ ] are allowed. Occasionally, a space, backslash, and quotation mark work but must be preceded with a forward slash. Although valid, some e-mail providers do not allow these characters.
The username and e-mail addresses as a whole cannot begin or end with a period.
The e-mail must not have two or more consecutive periods.
E-mail Header
The first five lines of an E-mail message is called E-mail header. The header part comprises of following fields:
From
Date
To
Subject
CC
BCC

The From field indicates the sender’s address i.e. who sent the e-mail.

CC stands for Carbon copy. It includes those recipient addresses whom we want to keep informed but not exactly the intended recipient.

This is the final part of an e-mail message. It includes Name of Sender, Address, and Contact Number.
