I have been testing Popup Picker on my web sites. I tested peel away ads for one of my sites and it did not turn out very well for newsletter opt-ins. I think peel away ads are more suitable for special discount ads. I switched to pop over ad and my newsletter subscriptions doubled!

Subscribe to my newsletter to get the same script I used to double more newsletter subscriptions for free. Test it on your web site to see if it helps to increase the number of opt-ins.
