AfterShip Order Tracking

Very good app! I still am wondering if I ought to stop some of the notifications on my Shopify store or if I ought to rely on the notifications from AfterShip premium. Definitely worth the Premium price to customize notifications and have the embedded track number in their account. I like that they charge per shipment and it is nominal. My only negative is that it is a little tricky to test, but maybe because I'm a newb.
