A webmail application lets you send and receive emails via an Internet browser without the need to set up an e-mail in a program such as Thunderbird or Outlook. If you travel, for example, it is possible to check your e-mails from an Internet café and you will not need to download, install or set up anything. Webmail apps are advanced enough to present you with many options like using an address book or creating folders that can afterwards appear in your e-mail application. As the webmail app works with the messages within the server, it is crucial that you apply the IMAP protocol any time you set up an email account on your desktop. You can still use webmail if you pick POP, but old messages won't be available due to the fact that they'll have been downloaded on the computer. You can use webmail provided that there is any e-mail created inside your web hosting account and using an e-mail application before being able to use webmail isn't a requirement, so you can handle your electronic communication completely from a browser.
