REVIEWS
Customer Reviews
Feedback from merchants using this app in production.
"Exceptional experience. We needed some custom work done that was quite unique and support helped us get it completely set up. They literally built new functionality for us and added it to the app within a day or two. The prompt, clear and helpful communication makes it easy to recommend this app."
"I have received really good support from this app developer. Implements new features just for me."
"We have used this app for quite a while. There was a change recently that requires a pro level tier for the emails to be sent from our own hosting. We needed some help with getting the DNS name servers set up. We sent a message through the chat along with some screenshots and we were able to get it sorted out. Appreciate the accurate and quick help.""
