At a glance
Of the parcels that were eligible for PostNord Sunday delivery (the recipient postcode supports it and the parcel was booked on a Sunday-capable service), the share actually delivered on a Sunday. Sunday coverage is not a flat network-wide feature: it varies by country and by postcode within the PostNord network, so this gauge measures fulfilment of a promise you have already made to specific customers, not the network’s theoretical reach. Read over the trailing 30 days.
Calculation
Calculated automatically from your PostNord data. The card first builds the eligible population: parcels booked on a Sunday-capable PostNord service to a recipient postcode that PostNord lists as Sunday-covered for that country. Of that population, the numerator counts those whose delivery scan fell on a Sunday in carrier-local time. The deliberate design choice is that eligibility is the denominator, so the gauge measures how well you keep a promise you have already made and (usually) charged for, not how broad PostNord’s Sunday network is. A parcel that was eligible but delivered Monday counts against the rate. See the worked example below for a typical reading.Worked example
A Copenhagen-based premium grocery and gifting brand offers paid Sunday delivery at checkout for eligible Danish and Swedish postcodes (mostly the Copenhagen, Malmo, Stockholm and Gothenburg metros, where PostNord runs Sunday rounds). Reading taken at 09:00 CET on 14 Apr 26 for the trailing 30 days (15 Mar 26 to 13 Apr 26). Sunday-eligible parcels only:
The card reads 90.1 percent, above the
<85% alert floor. Five things to notice:
- Above the floor at aggregate, below it in one cluster. Malmo / Gothenburg at 77.4 percent is already breaching in isolation. The aggregate gauge can sit comfortable while a specific metro fails the customers who paid for the upgrade. Always read the cluster split, not just the dial.
- Sunday delivery is a paid premium, so a miss is worse than a normal late. A customer who paid extra for Sunday and received Monday is owed a refund of the upgrade fee at minimum, and is more likely to churn. Pair with
shopify.refund_rateto see the downstream cost. - Coverage is postcode-level, so checkout copy must match. If your checkout offers Sunday delivery to a postcode PostNord does not actually run on Sundays, you create a guaranteed miss. The 77.4 percent Malmo cluster is worth checking against PostNord’s current Sunday postcode list: some of those parcels may never have been deliverable on Sunday.
- 117 missed Sunday deliveries is the workload. 90.1 percent of 1,180 leaves 117 parcels that missed the Sunday promise, each a likely refund and CS contact. Read with Late Shipments and First-Attempt Delivery Rate.
- Sunday volume is small, so do not over-react to a single bad week. 1,180 parcels over 30 days is roughly 270 a week; a five-parcel swing moves the gauge a point. Use the 30-day reading for the trend and investigate clusters rather than the headline.

Where to look in PostNord’s own tooling: Open the PostNord Portal (portal.postnord.com) → shipment / parcel search, filter to your Sunday-capable service, and inspect the delivery date and day-of-week in each parcel’s tracking timeline. To verify which postcodes are genuinely Sunday-covered, check PostNord’s current Sunday-delivery postcode coverage for the destination country, since coverage areas change and a postcode dropped from the Sunday network will look like a “miss” on this card when it was never deliverable. For programmatic checks, pull the delivery event from the PostNord tracking API and read its local-time day-of-week. The closest like-for-like view is Sunday-capable service, last 30 days, delivery scan day-of-week = Sunday, divided by eligible parcels. Why our number may legitimately differ from PostNord’s portal:Known limitations / merchant FAQs
Why is my Sunday coverage below 100 percent even though I only offer it where PostNord supports it? Coverage areas drift and recipients are not always in. Even within a Sunday-covered postcode, a Home delivery needs someone to answer, and PostNord’s Sunday rounds can be cut for weather, staffing or volume. The gauge measures the promise actually kept, so it will rarely sit at 100 percent. Aim for 90 percent plus and investigate any cluster under the 85 percent alert floor. My checkout offers Sunday delivery but some of those postcodes are missing on this card. Why? A postcode that is not in PostNord’s current Sunday-coverage list is not eligible, so it does not enter the denominator here. If your checkout still offers Sunday to that postcode you are creating guaranteed misses (those parcels deliver Monday). Reconcile your checkout’s Sunday-eligible postcode list against PostNord’s published coverage and remove the gaps. Should a Sunday parcel delivered Monday be a refund? Commercially, yes for the upgrade fee. The customer paid for Sunday and did not get it. This card sizes the exposure; pair it withshopify.refund_rate and your refund policy to decide whether to auto-refund the upgrade or handle it on contact.
Why is the gauge so jumpy week to week?
Sunday volume is a small slice of total parcels, so the denominator is small and a few missed parcels move the gauge several points. Read the 30-day reading, not a daily or weekly snapshot, and act on clusters rather than the headline.
Does Sunday coverage differ between Sweden, Denmark, Norway and Finland?
Yes, substantially. PostNord’s Sunday-delivery footprint is strongest in the Danish and Swedish metros and thinner elsewhere, and Norway’s non-EU status and different network mean weekend coverage there behaves differently again. Read OTD by Nordic Country alongside this card so a country-level network limit is not mistaken for an operational failure.
How does this relate to first-attempt success?
Closely, for Home parcels. A Sunday MyPack Home delivery to an empty house is both a Sunday miss and a first-attempt failure. A Sunday MyPack Mailbox parcel cannot fail an attempt, so shifting Sunday-eligible volume to Mailbox where the SKU allows lifts both this card and First-Attempt Delivery Rate.
