Apparently there is not a way to look at how long my carrier is taking to deliver my packages. We have a sneaking suspicion that our carrier dropped the ball this season and often took 4 weeks to deliver packages. We have no way of figuring this out currently. Would be awesome if there was an option in the shipments section to pull that information via export.
You can create an export of this. Go to Shipments -> Export shipments -> Custom export. Then click on the "Advanced options" button and you'll see "Delivery - Date" as a value. You can then add that into your report with whatever other parameters you need!
Let me know if that helps!
