Some little known ways to use your Gmail address that can give you greater control over your inbox and save your some time and headache. When you choose a Gmail address, you actually get more than just "yourusername@gmail.com." Here are two different ways you can modify your Gmail address and still get your mail.
Append a plus ("+") sign and any combination of words or numbers after your email address. For example, if your name was piyushfan@gmail.com, you could send mail to piyushfan+friends@gmail.com or piyushfan+mailinglists@gmail.com.
Insert one or several dots (".") anywhere in your email address. Gmail doesn't recognize periods as characters in addresses -- we just ignore them. For example, you could tell people your address was piyush.fan@gmail.com, piyush.fan@gmail.com or pi.yu.shfan@gmail.com.
The real value in being able to manipulate your email address is that it makes it really easy to filter on those variants. For example you could use piyushfan+bank@gmail.com when you sign up for online banking and then set up a filter to automatically star, archive or label emails addressed to piyushfan+bank. You can also use this when you register for a service and think they might share your information.
