Webmail is a really useful substitute for computer and smart phone e-mail applications if you don't have access to your laptop or computer and also you don't have a smartphone. You will be able to access your e-mail messages through virtually any browser, so you can keep in touch with friends and family if you take a trip and you go to an Internet cafe, for instance. Webmail applications are rather advanced, so you will not only be capable to send out and receive e-mails, you can also use an address book, make a customized signature or even set up new folders, that can later show up in your PC e-mail program. It is important to know that the emails available in the webmail are the ones on the server, so in case you create an email address in a PC app using the POP protocol, the messages will be saved on your desktop and they won't be available in the webmail. The answer in cases like this is to use the IMAP protocol when you create your emails in a desktop client.
