Activision using blizzard email to spam

Support site feedback is the closest option relative to my problem. I never signed up to receive COD emails. I generally dislike activision’s business practices and therefore don’t want to hear from them. I want mail about wow, warcraft, starcraft and diablo. Please stop using blizzard players to spam activision stuff on me. If theres someone thats more qualified with that department I could speak to I’ll be on my marry way over there, thank you.
