A webmail app enables you to send out and receive emails via an Internet browser without having to set up an e-mail in an app like Outlook or Thunderbird. When you travel, for example, you are able to check your emails from an Internet café and you will not need to download, install or set up anything. Webmail applications are advanced enough to provide you lots of options like having an address book or creating folders that will afterwards show up in your e-mail app. As a webmail software works with the messages within the server, it is essential that you use the IMAP protocol when you create an email account on your computer. You may still use webmail if you choose POP, but old messages won't be accessible due to the fact that they'll have been downloaded on the PC. You can use webmail provided that there is any email address created inside your web hosting account and using an e-mail app before being able to use webmail isn't a prerequisite, so that you can manage your digital communication solely via a web browser.
