What CPA offer to promote on Propel Media?

Hi,
I want to ask about what CPA Offer especially Sweep/Giveaway that can promoted on Propel Media PPV?
I already try sweep offer from CPALead and CPAGrip but almost all offer were rejected, due to the Push Notification behaviour on the offer. Are there any cpa offer that don't use push notification? Which network? Any recommendation?
