Webmail is a really useful alternative to desktop and smartphone e-mail apps if you don't have access to your laptop or computer and also you do not have a smart phone. You'll be able to access your e-mail messages through virtually any Internet browser, so that you can stay in touch with friends and family when you travel around and you visit an Internet cafe, for instance. Webmail apps are rather advanced, so not only will you be capable to send out and receive messages, you can also make use of an address book, make a custom signature or even make new folders, that can later on appear in your PC email app. You should know that the e-mails displayed in the webmail are the ones on the server, so in case you set up an e-mail in a PC program with the POP protocol, the messages will be downloaded on your PC and they will not be available in the webmail. The answer in this instance is to use the IMAP protocol when you set up your emails inside a PC app.
