Webmail is a really useful substitute for PC and mobile phone email applications if you do not have access to your personal machine and you don't have a smartphone. You'll be able to access your e-mail messages through any web browser, so you're able to remain in touch with people if you take a trip and you stop by an Internet cafe, for instance. Webmail applications are rather advanced, so not only will you be able to send out and receive messages, but you'll also be able to use an address book, create a custom signature or even make new folders, that will afterwards show up in your PC email app. You should know that the emails available in the webmail are the ones on the server, so if you set up an email in a PC program with the POP protocol, the messages will be saved on your computer and they won't be accessible in the webmail. The solution in this instance is to apply the IMAP protocol any time you create your e-mails in a desktop client.
