A webmail app lets you send and receive emails by way of an Internet browser without the need to set up an email inside an app like Outlook or Thunderbird. When you take a trip, for example, you'll be able to check your email messages from an Internet café and you will not need to download, install or configure anything at all. Webmail apps are advanced enough to offer you a great deal of options like having an address book or creating folders that can later appear in your e-mail app. As the webmail application works with the messages on your server, it is vital that you apply the IMAP protocol if you create an e-mail account on your desktop. You can still use webmail if you choose POP, but older emails will not be accessible due to the fact that they'll have been downloaded on the PC. You can use webmail provided that there is any e-mail created in your hosting account and using an e-mail app before being able to use webmail is not a requirement, so you can control your electronic communication solely from an Internet browser.
