Gmail is currently rated as the most popular e-mail client in the whole world. It offers you a clean and simple interface that is very easy to navigate and look at. If you have an account, you might not know that there is a settings page integrated in it. It's kinda easy to miss and even if you saw it I highly doubt anyone ever took the time to explore Gmail's setting page. Anyways, I took a quick stroll inside (so you don't have to) and found some very, very interesting features that Google had probably forgotten to mention.
