The squeeze page would be simple, like
"This offer is simple, and I will pay you $1 via PayPal after you subscribe to my list, and it is not joking, I am serious. Just subscribe and I will tell you how you can get the $1 immediately."
I will promote this squeeze page via good solo ads providers, and it only last for several days one time. In the first follow up message, I will tell subscribers that they must reply this message and send their paypal id to me.
The conversion rate should be great, and the response rate should be surprising too. Then I will have a good relationship with every subscriber from the start.
What do you think about this idea?
