Do you know the hidden secret of Google in gmail ? you can create many different Gmail account with one Gmail account . this mean you can transform one Gmail account in different way.if you are thinking why i have need of different Gmail account? answer is better e-mail grouping. you can create different Gmail account with your original Gmail account with the help of dot(.) and Plus (+) but you would not be able to log on with your newly created Gmail ID.
Suppose your Gmail ID is xyz@gmail.com. you can create following Gmail ID
x.yz@gmail.com
xy.z@gmail.com
x.y.z@gmail.com
x+yz@gmail.com
xy+z@gmail.com
above E-mail ID are possible because Gmail does not consider Dot(.) and (+) as a character if anybody send you mail on x.y.z@gmail.com it would get deliver to your original one i.e. xyz@gmail.com. your newly created e-mail ID will help you to save your original e-mail ID from Spam Mail.
