Electronic mail, or email, is a method of exchanging digital messages between people using digital devices such as computers and mobile phones.

Email first entered substantial use in the 1960s and by the mid-1970s had taken the form now recognized as email.

Email operates across computer networks, which today is primarily the Internet.

Some early email systems required the author and the recipient to both be online at the same time, in common with instant messaging.

Today's email systems are based on a store-and-forward model.

Email servers accept, forward, deliver, and store messages.

Neither the users nor their computers are required to be online simultaneously; they need to connect only briefly, typically to a mail server or a webmail interface, for as long as it takes to send or receive messages.

A home page or a start page is the initial or main web page of a website or a browser.

The initial page of a website is sometimes called main page as well.

Advertising is an audio or visual form of marketing communication that employs an openly sponsored, nonpersonal message to promote or sell a product, service or idea.

Sponsors of advertising are often businesses who wish to promote their products or services.

Advertising is differentiated from public relations in that an advertiser usually pays for and has control over the message.

It is differentiated from personal selling in that the message is nonpersonal, i.e., not directed to a particular individual.
