A mail client is a computer program that a person can use to send or
receive electronic mail, also known as "email." Typically, a mail
client program enables a user to compose and send messages, to
retrieve messages into an inbox on the computer where the mail client
runs, and to dispose of the messages by deleting or filing them.
The user must have electronic mail service somewhere else and have a
network connection between the client computer and the computers that
provide the service.
There are a number of free mail client programs. I will list links to
a few well-known ones, as well as links to pages listing more.
Eudora is a popular email program with a good reputation.
Thunderbird comes from Mozilla Corporation, makers of the Firefox browser.
Microsoft offers Outlook Express. If you have a version of Windows
that is not too old, you probably already have it. Microsoft does not
seem to have a home page for Outlook Express, probably because it is
provided bundled with other products, so I will refer you to
Wikipedia's article on it.
The Tucows website lists eleven free email client programs, including
The Nonags website lists fourteen.
You don't normally need to do anything to activate an email client
program. Such a program typically has options you can tweak to
control it, and at a minimum, you must tell the program the names of
the servers, the computers that provide email service. The details of
the way to do this will be different for different programs.
I hope this information is helpful. If you need more detail or
clarification, please ask for a clarification and I will explain at
