Webmail is a really practical substitute for desktop and smart phone e-mail apps if you do not have access to your laptop or computer and you don't have a smartphone. You'll be able to gain access to your email messages through any browser, so you can remain in touch with friends and family if you travel and you drop by an Internet cafe, for example. Webmail apps are rather advanced, so not only will you be able to send out and receive messages, but you'll also be able to make use of an address book, set up a customized signature or perhaps set up new folders, that will afterwards show up in your PC e-mail app. It is important to know that the e-mail messages available in the webmail are those on the server, so in case you create an email address in a PC app while using POP protocol, the messages will be downloaded on your computer and they will not be accessible in the webmail. The answer in this case is to apply the IMAP protocol any time you create your e-mails in a computer application.
