At a glance
Share of EasyPost-booked parcels delivered to the addressee on the first delivery attempt, across all underlying carriers, over the trailing 30 days. A parcel that needed a re-attempt, a redelivery, or a collection from a depot or access point did not deliver first time. A falling rate means more re-attempt cost, more “where is my order” contacts, and a higher chance the parcel ends up returned to sender. The alert fires at <85%.
What it tracks
First-attempt delivery rate is the proportion of delivered parcels whose first carrier delivery attempt succeeded, read from the EasyPost Tracker objects across every underlying carrier (USPS, FedEx, UPS, DHL, regional). The card derives it from the carrier scan history in each Tracker’stracking_details: a parcel that shows an “attempted, no answer”, “redelivery scheduled”, “held at access point” or “carrier collection” scan before its delivered scan is counted as a non-first-attempt delivery. Because EasyPost aggregates carriers, the rate blends each carrier’s last-mile behaviour, so a dip is often concentrated in one carrier or one region rather than spread evenly. First-attempt failure is largely an address-quality and recipient-availability problem: incomplete addresses, missing unit numbers, and signature-required services drive most of it. It is a leading indicator for both Returned to Sender and customer-service load, so a 30-day decline here usually shows up as rising returns and contacts a week or two later. The 30-day window smooths the day-to-day noise that volume seasonality would otherwise introduce.
Reconcile against the EasyPost Dashboard Trackers view, matching All Carriers and Last 30 Days, then against each underlying carrier’s own tracking portal for the per-scan detail; expect small differences from tracking-event latency and carrier-local scan timestamps.
