Without giving away too many explicit details, I gained access to a website and managed to snatch their email list of ~2.3k users that signed up for this gaming related tournament website that recently hosted a very high level qualifier tournament. This game is a "pay-to-win" VERY popular online TCG/CCG and has some big names on the TCG scene in the list. People are spending hundreds to play this game. How do I go about targeting/monetizing what I found? I'm sure that 95%+ of the emails are active and I have access to newer signups as well. Given the right marketing I'm certain I can achieve a high CTR.
