LuminAID review for Track by Loop

We ship most of our orders with USPS and were having issues with packages getting delayed and customers thinking they were lost. Customers would reach out asking us to reship their order once it stopped moving in tracking. Now we can proactively notify customers that we're monitoring their shipment and avoid having to re-ship as many orders. This has been the only app we've found that can do this, other popular tracking apps only notify you and the customer when the carrier flags it as delayed.
