So I'm not exactly a newbie, but this seemed like as good a place as any to ask this...
I usually have at least one or more pop campaigns running, and I remember reading that people are using things like Monetizer to boost their profit margin. Are there any threads in the forum or other resources you can recommend to try this? Any other suggested "tricks" like this to boost a pop campaign after you've got the traffic, landing page, and offer dialed in?
Do you want to build an own push list or monetize with third party push subs?
When you want to monetize with third party subs just add monetizer or propush me scripts to your lander.
You can add it to trigger a push promt when the user visits your LP and you can also add it to the backbutton.
Just check @jaybots long and boring follow along 
There he posts his push stats together with the campaign stats and it's not exaggerated to say that the push revenue often helped to be in profit overall.
