How is it deceptive? Are you feeling deceived because you are not sure if you are a member or not? They have your email. Either from this forum or elsewhere (maybe you signed up for a raffle somewhere). Your email address is thrown in a database and the email goes out to everyone in that database.
From what I've seen, Mr Blanc is like a VP or something and a big wig especially with the insurance side. So why not correspond with him? Would you expect marcus to correspond with you about purchasing insurance, roadside assistance, or even a sewer hose at camping world?
I don't see how it's deceptive. If they said you owed them money and was gonna garnish it or sue you for it, then yes. But you should know if you are a member or not. If you don't want to buy insurance, don't buy it.
