Preorder Now Presale Timesact

This app has everything I need! I love that they have a dual-option for both pre-order and subscribe to be notified so you don't lose potential customers who want to buy, but not buy pre-order. They also have amazing white-glove setup service where you get a 30-min video meeting of them walking through setting up your pre-order campaign with you and they will even offer to do a code cleanup of an previous pre-order apps you've tried. I'd definitely recommend!
