Webmail is a web application that permits you to work with an email account online through a web browser and without the need for configuring the account in a desktop e-mail app like Microsoft Outlook or maybe Apple Mail. This will make it possible to use your email messages from any destination or any laptop or computer if you're not able to use your personal computer - if you're on vacation and you go to an Internet cafe, for instance. Webmail clients commonly do not offer as much options as a regular desktop client, however, they still provide quite a lot of options, such as sending and receiving emails, configuring customized signature and making use of address books. If you setup an email address inside a PC app, you have to use the IMAP protocol in the process for those who like to check out all messages later using webmail, as the online app can't show e-mail messages from your PC if they have been previously downloaded with all the POP mail protocol.
