Tracking is helpful, but confusing at first. I like seeing delivery status in one place, since I get lost in different carrier sites. The setup for notifications took me a bit and I kept second guessing what I picked. Some updates came in late for a few shipments, or at least it felt like it. It works ok now, just not as simple as I hoped.
Really clean tracking view day to day. I like that everything shows up in one dashboard, so I am not bouncing between carrier sites to see where a shipment is. The delivery status updates feel current enough that I trust what I am looking at. The automated notifications are nice, but I had to tweak them a bit to avoid getting too many pings. Overall, it keeps me in the loop without being complicated.
Rate it, and the next carrier reading this page sees what you found.
