Whenever I remember about the mail ID I found most of the people has their mail ID in Gmail.com.
I am a user of Gmail from 2006 and every time I use this mail I came to know with one unique feature of Gmail.
Gmail is just like a wallet where you can Store you are all expensive things in one place.
Storing the contact is a unique feature of Gmail because of that if your phone is stolen or you use new phone it is very easy to transfer your all the contacts in your new phone.
