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.
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, email@example.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 Subject field indicates the purpose of e-mail. It should be precise and to the point.
CC stands for Carbon copy. It includes those recipient addresses whom we want to keep informed but not exactly the intended recipient.
BCC stands for Black Carbon Copy. It is used when we do not want one or more of the recipients to know that someone else was copied on the message.
