Recently I have been receiving emails from a domain permissionclub . com and even after trying to unsubscribe, I could not get removed fairly. So the issue was that how to stop such email senders who just don't want to stop sending you emails. I found a solution and here is the video I made while doing it. This is not a case if you have a free email address like gmail, yahoo or msn etc but email on your own domain like [email protected]   http://www.youtube.com/watch?v=iTVDpo3Ypzg
