A webmail app lets you send out and receive messages via an Internet browser without the need to set up an email address inside a program such as Thunderbird or Outlook. When you take a trip, for example, you are able to check your emails from an Internet café and you will not have to download, install or configure anything at all. Webmail clients are advanced enough to offer you many options such as having an address book or making folders that will afterwards show up 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 any time you set up an e-mail account on your computer. You can still use webmail if you pick POP, but old messages will not be available due to the fact that they'll have been downloaded on the computer. You can take advantage of webmail as long as there is any email address created in your hosting account and using an email application prior to being able to use webmail is not a prerequisite, so you can control your electronic communication entirely through a browser.
