SendWILL Popup Email Marketing

I just implemented the app so I can't speak to its performance just yet, but the customer service rep was excellent in helping me launch the app and answering any questions I had about its integration with my MailChimp account. Further, I didn't have to wait 20 minutes to get a response. The customer service rep responded quickly to all my questions and provided clear, easy to understand instructions. You can't beat that.
