Well, it was the first time that I was working with ZeroPark and I was not 100% satisfied with. My first issue is that they don't refund the first deposit of members and it does not matter if it's $100 or $1000.
My second issue is that their on-boarding program for new affiliates is not as valuable as it's described in the site so if you join in the hope of having a one-on-one coaching, (like it's said in explanation of program), you won't get it for sure.
I didn't test much their traffic yet so I can't say if it's quality or not but two above issues are enough for me to don't put them in my list (at least for now).
After like $300~500 Testing budget on different campaigns. it's barely profit, cool function and Good ui.. not bring me profitable since i copied other successful push campaign to their network but not work out for me.
One of the top leading push ad networks. Due to their massive volume it can be difficult to get campaigns profitable at first, so it's preferable to use them for campaigns that are already working for you on a different push network. Zeropark is a tough cookie, but once you get your campaigns to work, you will love the volume.
ZP Push is pretty good. Setting up campaigns is pretty easy, though I'd like to be able to include a large image with the message. ZP has lots of traffic and the quality is pretty good, though expect to pay a lot for the best sources, as is typical with ZP. When ZP allows advertisers to choose the browsers they want before starting a campaign, I'll be almost inclined to go with 5-stars, but I just hate having to throw budget at the first rush of Android Webview before I get a chance to block it.
Zeropark, is the source of traffic that I rarely use especially in Push notifications and Domain traffic, support is by email is impractical, approvals a bit slow and have somewhat strict policies in the case of push notifications, so that subtracts attractive from other sources.
Superb traffic quality. I was initially rejected by them but thanks to affLift community that I got approved later. I have been running CC submit offers on them through help of Nick and it has been really great. One thing that I didn't find good is that if you have missed the onboarding process then they don't allow you AM/chat support till you spend x amount/month. Which is a bummer and hence 1 less star.
Zeropark Push is my go-to traffic source for launching push notification ad campaigns. I love the look of their new interface and the fact that they have rule-based optimization (although I rarely use it for push campaigns).
I really like how fast they approve your campaigns.
When push notifications first became popular they were one of the easiest networks to use because they allowed you to easily split test different creatives without having to create separate campaigns.
