A webmail app lets you send out and receive e-mails through a web browser without the need to create an email address in a program like Outlook or Thunderbird. If you travel, for instance, it is possible to check your email messages from an Internet café and you will not have to download, install or configure anything. Webmail apps are advanced enough to present you with a great deal of options such as using an address book or making folders that will afterwards come in your e mail application. As the webmail application works with the messages within the server, it is necessary that you apply the IMAP protocol if you configure an email account on your PC. You can still use webmail if you select POP, but older emails will not be available due to the fact that they'll have been downloaded on your computer. You can use webmail provided that there is any e-mail set up with your web hosting account and using an email client prior to being able to use webmail is not a prerequisite, so you can manage your digital communication entirely from an Internet browser.
