Have you ever faced a situation where you open up a gmail for writing an important email and end up checking inbox and other stuff . Gmail is a product of google , so it is built with an awesome user experience and you might end up with something else than important thing while using it. Here is a growth hack technique from somewhere I read.. It is working very well for me..
Just bookmark this link on your browser.
https://mail.google.com/mail/?view=cm&fs=1&tf=1
