Filter Your Gmail Messages With Personalized Custom Email Addresses

Most people don’t realize that you can use multiple address variations of your basic “yourname@gmail.com” Gmail address. Gmail lets you put a plus (“+”) sign and any combination of words or numbers after your name. For example, yourname@gmail.com can become yourname+contests@gmail.com or yourname+hydrobill@gmail.com.
All messages sent to any of these different address variations will end up on your inbox. The benefit of using address variations is that you can easily add a filter to label and/or archive messages in a particular way, depending on different address variations you have created. This can help you better manage the different types of messages coming into your inbox.
