On average: is there a big difference between the conversion rate of a single-opt-in vs Double Opt-in?
I'm talking about Dating site offers in particular. Same offer & LP, but one is a single opt-in and the other one is a double-opt-in.
In the process of testing this. Will let you know!
EPC should be the same, and that's all that matters.
Doing some tests ... Conversion Rate of the Single Opt-In is much higher. At least double.
