Ordersify: Restocked Alerts

This app is great when it works completely. My customers love being able to get notifications when products they're waiting on go back in stock. The app has been easy to configure. My only issue is that during the last month not all notifications have gone out. I have had to manually go through my unsent notifications to find the ones that have slipped through the cracks. It's not the worst problem but definitely takes time away from my day.
