Rancourt & Co. review for Mailmunch Forms for Mailchimp

I've been using this app for over a year. It has so many bugs. Features we set up will just stop working and I will not be notified until a customer alerts us that they couldn't sign up for our list or receive a coupon code. Currently, our coupon autoresponder stopped working and the app is prompting me to upgrade to use this feature but I've had the PRO LEVEL subscription since day one. This app is totally unreliable.
