A webmail app lets you send and receive messages through a web browser with no need to set up an e-mail address inside an app such as Thunderbird or Outlook. When you travel, for instance, it is possible to check your e-mails from an Internet café and you will not have to download, install or set up anything. Webmail apps are advanced enough to provide you with a number of options such as having an address book or creating folders that can later on appear in your email application. As a webmail software works with the messages on the server, it is crucial that you employ the IMAP protocol any time you create an e-mail account on your computer. You may still use webmail if you select POP, but old e-mails won't be available since they'll have been downloaded on your computer. You can use webmail as long as there is any email address set up in your hosting account and using an e-mail app before being able to use webmail is not a prerequisite, so that you can manage your digital communication completely from a browser.
