At a glance
Absolute count of DHL Paket consignments in the trailing 7 days that ended in a genuine non-delivery: undeliverable (unzustellbar), refused (Annahme verweigert), or returned to sender after all attempts and retention failed. This is the subset of exceptions that actually cost a customer their parcel, not the recipient-not-home scans that self-resolve. The alert fires when failures exceed 2 percent of total shipments.
What it tracks
The card counts consignments whose final or terminal tracking status is a true failure, drawn from the DHL Parcel DE Tracking API (/track/shipments) and keyed on the Sendungsnummer, with shipment totals from the DHL Paket Shipment API. It deliberately excludes the large, benign Empfänger-nicht-angetroffen bucket that recovers via Packstation, branch (Filiale), or neighbour handover; those sit on Exception Rate. A failure here means the parcel did not reach the addressee and now needs a re-ship, a refund, or a claim. It is a count, not a rate, because the count is the workload: each failure is a support contact, a replacement order, or a Nachforschungsauftrag in the making. The 7-day window keeps it tied to this week’s despatch decisions. Failures cluster by cause: bad address data (controllable upstream via Label Generation Success), refusal on cash-on-delivery or unexpected customs charges, and unresolved holds that time out into a Rücklauf, which then appears on Returned to Sender.
