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.
| What it measures | COUNT(Sunday-eligible parcels delivered on a Sunday) / COUNT(Sunday-eligible parcels), over the trailing 30 days. Eligibility = recipient postcode in a Sunday-delivery area AND parcel booked on a Sunday-capable PostNord service. The denominator is the promise; the numerator is the kept promise. |
| Data source | PostNord Shipping / Booking API (the chosen service code and Sunday-delivery flag), joined to the delivery scan from the PostNord tracking-event feed. Sunday-eligibility is resolved against PostNord’s postcode coverage for the destination country. |
| Clock used | The day-of-week of the delivery scan, in carrier-local Nordic time, must be Sunday for the parcel to score. |
| Time window | 30D (rolling 30 days). Sunday volume is a small slice of total volume, so daily readings are meaningless; read the 30-day gauge. |
| Alert trigger | <85%. Below 85 percent, more than one in seven customers who were promised and (often) paid for Sunday delivery did not get it, which is a refund and trust problem on a premium service. |
| Scope | Sunday-eligible parcels only. Parcels to postcodes without Sunday coverage, and parcels not booked on a Sunday-capable service, are excluded from both numerator and denominator. |
| Roles | owner, operations |
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:| Metro cluster | Eligible parcels | Delivered on Sunday | Coverage |
|---|---|---|---|
| Copenhagen (DK) | 540 | 519 | 96.1% |
| Stockholm (SE) | 410 | 366 | 89.3% |
| Malmo / Gothenburg (SE/DK) | 230 | 178 | 77.4% |
| All Sunday-eligible (this card) | 1,180 | 1,063 | 90.1% |
<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.
Sibling cards merchants should reference together
Sunday coverage is a premium-service promise. Pair it with these to manage it:| Card | Why pair it with Sunday Delivery Coverage | What the combination tells you |
|---|---|---|
| On-Time Delivery Rate | The all-service outcome metric. | Sunday is a sub-population; if Sunday coverage drops but overall OTD holds, the issue is the weekend round specifically. |
| First-Attempt Delivery Rate | Sunday hand-offs depend on the recipient being in. | A low Sunday first-attempt rate may explain a low coverage rate: the round ran, but no one answered. |
| OTD by Nordic Country | Sunday coverage differs sharply by country. | Confirms whether a coverage dip is one country’s weekend network rather than yours. |
| Late Shipments | The absolute count of missed promises. | Converts the coverage percentage into the refund and CS workload it generates. |
| Shipments by Service | How much volume rides the Sunday-capable service. | Sizes the business impact of a coverage change. |
| MyPack Mailbox vs Home Delivery Split | Mailbox parcels do not need a recipient; Home parcels do. | A Sunday Home delivery to an empty house fails; mailbox-eligible Sunday parcels are more reliable. |
Cross-connector: shopify.refund_rate | Downstream impact. A missed paid Sunday delivery is a near-certain refund. | A coverage dip on a high-Sunday-volume brand precedes upgrade-fee refunds within days. |
Reconciling against the source
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:| Reason | Direction | Why |
|---|---|---|
| Carrier-local scan time | Boundary days off | Delivery scans are timestamped in Nordic local time. A delivery at 00:10 Monday local could be the tail of a Sunday round; we use the scan’s local day-of-week, which is the customer-felt day. |
| Tracking-event ingestion lag | Ours can lag | Sunday delivery scans may ingest in a later batch, so a Sunday-evening reading can understate coverage until Monday morning. |
| Postcode coverage drift | Either | If a postcode leaves PostNord’s Sunday network mid-period, our eligibility set may differ from PostNord’s current list, shifting the denominator. Re-check coverage when a cluster drops. |
| Eligibility definition | Either | We require both a Sunday-capable service AND a Sunday-covered postcode. A portal view filtered only by service (not postcode) will include parcels that were never Sunday-deliverable, making the portal rate look lower. |
| Delivered vs attempted | Ours lower | A Sunday round that attempted but did not complete (recipient out) counts as a miss here. The portal may show an attempt event that looks like activity but is not a delivery. |
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.
