Gmail is definitely one of the best email service provided by Google. One can send emails to anyone, anywhere in the world with just a click. The option to attach files likes images, pdf, e.t.c. with the message allows us to communicate more efficiently. Very easy to use, I believe that if a person has a basic knowledge of how computer and internet works he would be able to send and receive mails with ease. Customer support and service provided by google has always been excellent.
