Webmail (or Web-based e-mail) is an e-mail service which is usually accessed through a web browser, instead of an email client such as Microsoft Outlook. Some well known versions are Gmail, Windows Live Mail and Yahoo! Mail. One of the advantages of using web-based e-mail, as with other Cloud computing is that users needn't have their own computer. They can access and write their mail from anyone else's computer that has a web browser connected to the internet.
