Webmail is a useful substitute for computer and smart phone e-mail applications if you do not have access to your personal machine and also you don't have a smart phone. You'll be able to gain access to your email messages through virtually any browser, so you can keep in touch with friends and family when you take a trip and you stop by an Internet cafe, for example. Webmail applications are rather advanced, so you will not only have the ability to send and receive emails, you can also work with an address book, make a custom signature or perhaps set up new folders, that will afterwards appear in your desktop email application. It is important to know that the emails available in the webmail are the ones on the server, so in case you set up an e-mail in a PC program with the POP protocol, the messages will be downloaded on your hard drive and they won't be available in the webmail. The solution in this instance is to use the IMAP protocol any time you create your emails inside a desktop computer app.
