I've tested various push affiliate programs, and now I've been monetizing with zpush for six months. In general, I am satisfied. It was zpush that had the most income. My traffic is mostly CIS countries and it usually converts less, while Zpush CIS CPM is almost the same as RU one. They do not always reply to them in tickets, but they do it regularly in the support. So, I can recommend this affiliate program, monetize yourself, especially if you have CIS traffic)
