Next, the @ (at sign) is used as a divider in the e-mail address and is always required for all SMTP e-mail addresses and was first used by Ray Tomlinson.

Finally, computerhope.com is the domain name of where the user belongs.

How to send and receive e-mail

To send and receive e-mail messages you can use an e-mail program, also known as an e-mail client such as Microsoft Outlook or Mozilla Thunderbird. When using an e-mail client you must have a server that stores and delivers your e-mail this service is provided by your ISP but can also be a service provided by another company. The e-mail client will connect to the server to download all new e-mail and deliver any unsent e-mail.

An alternative way of sending and receiving e-mail and a more popular solution for most people is an online e-mail service or webmail such as Hotmail, Gmail, and Yahoo Mail. Many of the online e-mail services including the above examples are free or have a free account option.

Writing an e-mail

When writing a new e-mail message a window similar to the example below will appear. As can be seen, several fields are required when sending an e-mail, the From or Reply-To is a field that is automatically filled out and is where the e-mail returns if a reply is made. Next, the CC or Carbon Copy field allows you to send a copy of the message to another e-mail address, but is not a required field. The To field is where you type the e-mail address of who you are sending the e-mail address. Next, the subject line although not required should be a few words describing what the e-mail is about. Finally, the message body will be the location you type your message and is what will contain your signature.
