A few random thoughts for you. I used to have huge ethical issues with spam. Not so much anymore, since the anti-spammers have gotten such a clear upper hand in the arms race, making spam only a minor annoyance for anyone who cares about it at all. But that means that spam-based marketing is stupid. You know it. I know it. Your client doesn't. You want to convince him. Is that going to happen? Someone who has already decided to spend thousands of dollars to do something that he thinks is an industry-standard practice, is hardly going to be easy to dissuade. Yes, you could look for those statistics. You'd almost certainly find them. But would it help? That said, here are some questions that I feel like I might be asking myself, if I were you: - Is your client asking you to open yourself up to a lawsuit? Is this a problem for you? - Is your client asking you to help him damage your reputation? - You seem to be interested in keeping a good long-term relationship with your client. However, you have seen that he is clueless about how to obtain new customers (= sources of revenue, which is where he gets the money to pay you). Does this affect the value you place on your relationship with him?
