I do not mind if you are using Gmail than Windows Live Mail (formerly Hotmail), as I’m a Gmail fan myself (loads way faster for me) 😉

Have you ever wonder which website gave out your email when you register yourself in some website? Here’s a simple trick you can use:

If your Gmail login name was username@gmail.com and you went to samplesite.com to fill out a registration form, instead of just entering username@gmail.com as your email, enter it as username+samplesitecom@gmail.com instead. When Gmail sees a “+” in an email address, it uses all the characters to the left of the plus sign to know who to send it to. In this example it would still send it to username@gmail.com.

Now whats cool is if you search Gmail for username+samplesitecom, you will see all massages that were sent to that email address.

To see who is responsible for sending a specific message click the Show Details link and you will see the complete address.

Does it work? I haven’t try it out but reports say that it works!

Does Windows Live Mail have something similar? Is there something in the works? What do you think of this feature? Leave a message! 🙂

Update: According to Kevyn, Yahoo Mail already has this implemented. It is called “AddressGuard”. You use [basename]-[keyword]@yahoo.com. Thanks Kevyn!
