Webmail is a really practical substitute for desktop and mobile phone email applications if you do not have access to your laptop or computer and you don't have a smart phone. You'll be able to gain access to your e-mails through virtually any Internet browser, so you can remain in touch with people when you take a trip and you go to an Internet cafe, for instance. Webmail applications are rather advanced, so not only will you be capable to send out and receive messages, you can also work with an address book, create a customized signature or even create new folders, that can afterwards appear in your desktop e-mail app. It is important to know that the e-mails available in the webmail are the ones on the server, so if you create an email address in a PC program using the POP protocol, the messages will be saved on your desktop and they will not be accessible in the webmail. The answer in this case is to apply the IMAP protocol whenever you create your emails in a computer app.
