We assure you that we do not want anyone to receive undesired solicitations/SPAM. We only deal with highly reputable services which have opt-in policies that entirely prevent unwanted solicitations without your approval. We are troubled by your suggestion that we may have directly or indirectly been the cause of your e-mail address being used and we will look into the matter further, by reinvestigating our promotional partners. We will have a couple of our developers go through the signup process and see if they receive SPAM as a result.
One other possibility I would raise, which you may not have considered, most mail services (at least all of the ones I'm familiar with, Yahoo/Hotmail/mail.com/etc.) SPAM their own accounts, that is, they distribute advertising offers to their own users, obviously to generate money for the service, over and above banner advertising. I am not sure if that may be what happened to you, or if that is the policy of the site where you created your mail account.
