Webmail is a convenient replacement for PC and mobile phone email apps if you do not have access to your personal computer and you don't have a smartphone. You'll be able to access your emails through any web browser, so you can stay in touch with friends and family if you travel around and you visit an Internet cafe, for example. Webmail applications are rather advanced, so you will not only be capable to send out and receive emails, but you'll also be able to work with an address book, set up a personalized signature as well as make new folders, that will afterwards come in your desktop email app. It is important to know that the email messages available in the webmail are the ones on the server, so if you set up an e-mail in a desktop app using the POP protocol, the messages will be downloaded on your PC and they won't be accessible in the webmail. The solution in this case is to use the IMAP protocol when you create your emails inside a desktop client.
