For the past 16+ years, I have been monetizing purchased data (email) using PPL (pay per lead...lead generation) offers.
With PPL offers there is no credit card/ purchase required. All a user has to do is fill out a form, so conversion rates are typically much higher that offer that require a sale.
I acquire data because I'm building assets that I then own and can market to over and over at low cost. Compared to buying traffic, that so often just generates a bunch of clicks and fails to turn a profit. Or using some free method that typically isn't worth the time spent to implement.
So by combining the two, I promote PPL offers because it offers the path of least resistance to generating conversions and converting the data into cash producing assets.
