At a glance
Share of Shippo-booked parcels that were delivered on the carrier’s first delivery attempt, with no “attempted, no answer” or “carded for redelivery” event in the tracking history. A high first-attempt rate keeps reverse-logistics cost down and customers happy; a falling rate signals address-quality problems or carrier last-mile strain across the carriers Shippo aggregates.
What it tracks
This card reads First-Attempt Delivery Rate for the selected period over a rolling30D window. The denominator is every Shippo shipment that reached a terminal DELIVERED tracking status in the period; the numerator is the subset whose tracking history shows no failed-attempt event before the delivered scan. Shippo normalises carrier scans into a common tracking model, so a failed attempt typically surfaces as a TRANSIT status with a sub-status such as delivery_attempted, notice_left, or package_held. Because Shippo is a multi-carrier aggregator, this rate blends the underlying carriers (USPS, UPS, FedEx, DHL, Canada Post, Australia Post and others) into one figure, so a dip is usually concentrated on one carrier or lane rather than network-wide. Use OTD by Route and Shipments by Underlying Carrier to localise the cause, and pair with Failed Deliveries and Returned to Sender for the downstream cost view. The alert fires when the rate falls below 85%, the point at which redelivery handling and “returned to sender” charges start to erode despatch margin. The most common controllable driver is address quality, so a sustained dip is worth checking against address-validation pass rates at label time.
