Nice alerts, simple to follow. I get the shipping notifications and can tell what is going on without reading a bunch. Sometimes the messages feel a little repetitve, but it is still helpful for me. Setup was ok, just a tad clunky.
Nice idea, a little quirky. I like having shipment updates in one dashboard, but a couple deliveries showed a vague status that did not explain much. I still use it, just not as my only source.
Webhooks are the best part for us. I subscribed to tracking events and the payloads are consistent enough to map into our dashboard without extra guessing. The delivery status progression matches what I see on carrier sites most of the time. Testing in sandbox was straightforward, and switching to live keys was painless. My only nit is I had to re-read the docs to confirm a couple event names.
Decent tracking, but support felt slow. I asked about a delivery status mismatch and it took awhile to get a clear answer. The tracking page is simple, which I like, but the delay was frusterating.
Rate it, and the next carrier reading this page sees what you found.
