A webmail application allows you to send out and receive emails through browser with no need to create an e-mail address inside a program like Thunderbird or Outlook. When you take a trip, for instance, you'll be able to check your e-mail messages from an Internet café and you will not need to download, install or configure anything. Webmail applications are advanced enough to provide you a lot of options like using an address book or making folders that can later appear in your email app. As a webmail application works with the messages within the server, it is important that you use the IMAP protocol any time you configure an email account on your computer. You can still use webmail if you choose POP, but old e-mails won't be available since they will have been downloaded on the computer. You can use webmail as long as there is any sort of email created with your web hosting account and using an e-mail application before being able to use webmail is not a prerequisite, so you can control your digital communication solely through a browser.
