Thanks for another detailed explanation. Precisely that is what all Campaign managers should think about. Campaign managers should ask casinos about their Bankroll and their promotion plans. How long they are on the market, and what do they expect from this campaign? If their expectation is too high, You have to explain how it works and why they should/shouldn't run the campaign now.
Moreover, I believe most casinos don't want to reveal their bank roll. Especially when it's low, but they pretend it's pretty much high. So, If they don't share their plan with you, it will be a challenging job for you, but the ultimate loss is theirs.
BTW, It will be good if you can add this post to your service thread, so you don't have to explain them every time. Your potential clients should be aware of that.
