Lifter Pop‑Up Window

I have only been using this app for about 2 days now! So far its great & works seamless once I had set it up. The price monthly for the app is kind of expensive because I use mailchimp & the package for the mailchimp integration is $9 monthly. Set up was pretty easy only thing I would suggest is the app inform customer of the dimensions of the custom made image for the pop up window. I had a lot of trail & error but once I knew it was 600 X 400 was the perfect size everything else worked great.
