Webmail is a piece of software that permits you to work with an email account online via a browser and with no need of configuring the account in any desktop computer email client such as Microsoft Outlook or perhaps Apple Mail. This will make it possible to use your e-mails from any place and any personal computer if you aren't able to use your own computer - when you're on holiday and you go to an Internet cafe, for instance. Webmail clients commonly do not offer as much options as a regular desktop computer app, however, they still feature lots of options, like sending and receiving e-mails, configuring custom-made signature and making use of address books. If you setup an email address inside a desktop computer app, you have to use the IMAP protocol during the process in case you want to see all messages later using webmail, because the online client can't show emails from your computer if they have been already downloaded while using POP mail protocol.
