Clarus Marketing Group freeeshippping.com Word "click" imbeded in every email url from vendors who do business with freeshipping.com Middletown Connecticut

When shopping on Kohl's web site recently the freeshipping.com add pops up at the end of my transaction. I clicked to find out more about it and added my email address.  Aftere adding my email which was the only way to find out more info I discovered that there is a membership charge for this program and backed out of the process. 

As a result of providing my email I started to get any email from Kohls and other vendors they do business with that had every url link in the email embedded with the word "click" rerouting me whenever I accessed any of these links.

It only happens on sites that freeshipping.com does marketing for.  I have tried numerous times to stop these urls from being rerouted within certain vendors emails but have not been able to do so. I have even contacted freeshipping.com and they deny having anything to do with this even though it started immediatley after this freeshipping.com click

I have been unable to get this to stop no matter what I have tried and who I have talked with.
