A webmail application lets you send out and receive emails by way of a web browser without having to create an email address in an app like Thunderbird or Outlook. If you travel, for example, it is possible to check your emails from an Internet café and you will not need to download, install or set up anything at all. Webmail clients are advanced enough to present you with lots of options like using an address book or creating folders that will later on show up in your email app. As the webmail application works with the messages on the server, it is vital that you apply the IMAP protocol when you configure an email account on your desktop. You can still use webmail if you pick POP, but old emails won't be accessible because they'll have been downloaded on the computer. You can take advantage of webmail as long as there is any email set up in your website hosting account and using an email app before being able to use webmail isn't a requirement, so you're able to handle your digital communication completely from a browser.
