I think you might be surprised at how much money they make from sports betters that aren't interested in slots until they some new slot in a email peaks their interest for some reason and they decide to check it out just this once.
@TwitchySeal you’re absolutely correct as that’s how marketing works, by suggesting an additional product you may or may not have used before, hence I see nothing wrong with Stake promotions. However having said that if majority of their player’s want such an option of receiving separate mails then they may consider it, but if only few ask for this then I doubt they’ll implement it.
I was only suggesting that there is a good case that we may not end up with anything we like for a while if it is a cycle. So, let's assume that marketing here is a cycle, you get one sportsbook related, then slots, then dice, then x game, then y game, then z game and then back to sportsbook, right? I am just giving an example here, in that case from sportsbook related to sportsbook related there could be a whole month in that case.
So, what I am suggesting is doing it all at once, but doing it conditionally, so let's say there is a promotion right? Then do it on all games, but if you participate it via dice, then you can't participate also on sportsbook, or if you go into it via slots, can't do crash, and so forth. That way you give people option of 10+ different games, but they have only one chance to pick one thing and others are not allowed (for promotion, you can gamble regularly).
