A webmail app enables you to send out and receive emails through browser without the need to create an e-mail in a program like Thunderbird or Outlook. If you travel, for instance, you are able to check your emails from an Internet café and you will not need to download, install or set up anything at all. Webmail applications are advanced enough to provide you with a lot of options like having an address book or creating folders that will afterwards come in your e mail application. As a webmail application works with the messages within the server, it is vital that you apply the IMAP protocol if you create an email account on your PC. You may still use webmail if you pick POP, but older emails won't be available due to the fact that they'll have been downloaded on your computer. You can use webmail provided that there is any sort of email created in your website hosting account and using an email app prior to being able to use webmail isn't a requirement, so you can manage your digital communication completely through a browser.
