A webmail application permits you to send and receive emails via a web browser without the need to set up an email inside an app like Thunderbird or Outlook. If you travel, for example, you'll be able to check your emails from an Internet café and you will not have to download, install or set up anything. Webmail clients are advanced enough to provide you lots of options like using an address book or creating folders that will later show up in your email app. As the webmail app works with the messages on your server, it is crucial that you use the IMAP protocol when you set up an email account on your PC. You can still use webmail if you select POP, but older e-mails won't be accessible as they'll have been downloaded on the computer. You can take advantage of webmail provided that there is any e-mail created in your hosting account and using an email app before being able to use webmail isn't a requirement, so you're able to manage your digital communication entirely from a browser.
