Thanks a lot for your input so far.
Spin Palace is one of my favourites as well.

I got a mixed impression of Casino Rewards from posts on this board but if you say they´re reliable I´ll go with them. They have a normal rev share and this true wagering plan. The latter sounds pretty tempting but are there any catches to it that I don´t get?
@ Simmo
You´re right, in order to run a targeted campaign you need to have detailed information but at the moment I´m not yet in a position to fine tune my marketing because I lack that information.
