Webmail is a software application that lets you work with an e-mail account online via an Internet browser and without creating the account in any desktop computer email client like Microsoft Outlook or maybe Apple Mail. This will make it possible to make use of your email messages from any place or any personal computer if you aren't capable to use your personal computer - when you are on vacation and you visit an Internet cafe, for instance. Webmail clients usually do not offer as many possibilities as a common desktop client, but they still offer a number of options, including sending and receiving email messages, creating custom-made signature and employing address books. If you setup an e-mail address in a PC program, you need to use the IMAP protocol in the process for those who like to view all messages later working with webmail, as the online client is unable to display e-mails from your computer if they have been already downloaded while using POP mail protocol.
