Clearer.io Address Validator

There is a bug in its notification system, and as sellers, we cannot receive notifications when there is an order with the wrong address - even if we have set it up accordingly.
We have contacted the developer twice about this issue. Each time we contacted them, we received the notification email normally, but after a day or two, we no longer received the notification email.
We use an ERP system to process orders and it is important for us to be notified of address errors. I hope this review helps you guys improve your notification system.
