Webmail is a really practical alternative to computer and phone email apps if you do not have access to your personal computer and you don't have a smart phone. You'll be able to access your e-mail messages through virtually any web browser, so that you can stay in touch with people if you travel and you visit an Internet cafe, for instance. Webmail apps are rather advanced, so not only will you have the ability to send and receive messages, you can also use an address book, create a custom signature or even make new folders, that will later on come in your PC email app. You should know that the e-mail messages available in the webmail are the ones on the server, so in case you create an email address in a PC program while using POP protocol, the messages will be downloaded on your computer and they won't be available in the webmail. The answer in this instance is to use the IMAP protocol when you create your emails in a computer application.
