Webmail is a useful substitute for computer and smart phone e-mail apps if you don't have access to your personal machine and you do not have a smartphone. You will be able to gain access to your e-mail messages through virtually any browser, so you're able to stay in touch with people when you travel around and you go to an Internet cafe, for instance. Webmail apps are rather advanced, so not only will you be capable to send out and receive e-mails, but you'll also be able to use an address book, create a customized signature or perhaps make new folders, that will later show up in your desktop e-mail app. You should know that the email messages displayed in the webmail are those on the server, so in case you set up an e-mail address in a PC program using the POP protocol, the messages will be saved on your PC and they will not be accessible in the webmail. The solution in this instance is to use the IMAP protocol any time you create your e-mails in a PC application.
