Do you sign-up at various places only to find your email spam has increased? I have done this a few times and really had no way to prove that the site/company sold my email to others.

I did some searching and using a GMail account you can now find who has spammed you w/o having 100′s of emails setups.

To get started be sure to have a GMail account. If you do not have one then create one.

Once you have your GMail account you can sign-up at various services using the GMail account. The only difference from how normally enter our email is were going to add a keyword so we can later track where the spam originated from.

Let’s presume for a second that your email address is bluefurtest@gmail.com. If I sign-up for twitter I can add the keyword twitter to that email by using a +keyword. The email would look like bluefurtest+twitter@gmail.com.

If you add  the +keyword the email will still be sent to the main account of bluefurtest. To view if a spam was sent by one of your places you sign-up click on Show Details and you will see the +keyword where the spam was sent/sold from.

If you get stuck let me know in the comments.
