Webmail is a software application that permits you to use an e-mail account online through an Internet browser and without setting up the account in a desktop computer email client like Microsoft Outlook or Apple Mail. This will make it possible to use your e-mails from any location as well as any personal computer if you aren't capable to use your personal computer - when you're on vacation and you go to an Internet cafe, for instance. Webmail clients don't offer as much options as a regular desktop computer app, however, they still feature many options, including sending and receiving email messages, creating customized signature and employing address books. If you setup an email address inside a desktop computer program, you have to use the IMAP protocol during the process for those who like to check out all emails later utilizing webmail, because the online client can't display emails from your computer if they have been already downloaded while using POP mail protocol.
