If you're anything like millions of other people around the world, then you already know your email is much more than just a communication tool. It's the first thing you open in the morning and the last thing you close at night. It follows you around in your pocket and is there for you when all you can access is a web browser on a shared computer in some sad airport or train station cafe. It's a hub of creativity, productivity, detailed project briefings and dinner plans. It's your window to the world of work, and it's versatile and flexible enough to help you manage every other aspect of your life.
