A webmail app lets you send out and receive messages from an Internet browser without the need to set up an e-mail address inside a program such as 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 configure anything at all. Webmail apps are advanced enough to offer you a lot of options such as having an address book or making folders that will later on show up in your email client. As a webmail app works with the messages within the server, it is important that you apply the IMAP protocol when you create an e-mail account on your PC. You may still use webmail if you choose POP, but old e-mails will not be available since they will have been downloaded on the PC. You can use webmail provided that there is any sort of e-mail created with your website hosting account and using an e-mail client before being able to use webmail isn't a requirement, so you can manage your electronic communication completely via a web browser.
