On the penultimate day of 2025, Denmark’s national post operator, PostNord, delivered its final letter. The company has attributed this to a long-term collapse in letter volumes—down more than 90% since 2000—and to a business model that no longer works under current market conditions . It is easy to tell this story as the inevitable victory of the inbox and a clean break with a 400-year tradition. But Denmark is also where a more interesting question becomes visible: whether handwritten communication can survive—not as mass communication, but as a deliberate, “premium,” form of connection in a world saturated by screens and AI-generated text. The present crisis is straightforward in one sense: letters are declining globally because key uses were absorbed by digital media . Universal service obligations (USO) were historically financed by scale: when many people sent many letters, the marginal cost of serving remote routes was tolerable). When volumes fall, the fixed costs of daily delivery loom larger, and each remaining letter is asked to carry more of the system . Denmark illustrates the shift particularly clearly. As PostNord began removing roughly 1,500 red postboxes and prepared to end letter delivery, it signalled a strategic reorientation toward parcels—where volume growth and unit economics are more favourable. Denmark’s regulator reports that letter volumes fell from 170 million in 2022 to 147 million in 2023, while parcel volumes rose to 199 million—a clear pivot from correspondence to e-commerce logistics. Denmark is therefore a case example of a broader European problem: letters are increasingly expensive to deliver precisely because fewer people are sending them, and yet the political expectation of universal reach has not disappeared at the same pace. It is important to be precise: Denmark will still be able to send letters. The state has emphasised that nationwide posting remains possible, now primarily through a private operator, DAO . What changes is the institutional form and, with it, the expectations surrounding service: universality becomes less automatic as networks consolidate and services become more conditional on location, mobility, and digital confidence. Denmark is not alone in asking whether daily letter delivery can survive the twenty-first century. Finland has revised postal legislation so that stamped letters are delivered on three weekdays rather than five . In the UK, Ofcom has been exploring similarly reduced delivery frequency for letters as volumes fall and costs rise. At EU level, the European Commission has been preparing a new “EU Delivery Act” as part of its single market agenda, with the explicit intent to modernise—and potentially replace—the current framework built around the Postal Services Directive and cross-border parcel regulation . To understand why these changes are so vital, it helps to treat the postal system as infrastructure rather than as a service. Europe’s postal systems were never merely logistics; they were part of state formation—making territory governable, commerce legible, and distant communities mutually reachable. Early modern Europe developed powerful postal networks that linked courts, merchants, and administrative centres across fragmented political geographies . The nineteenth century then institutionalised “modern mail,” most famously through British reforms that turned postage into a standardised policy technology: predictable payment, broader access, and more reliable national coverage . Over time, comparable systems spread across Europe and became deeply embedded in how states and markets functioned. Internationally, the modern postal world was consolidated through rules and institutions. In 1874, the Treaty of Bern created what became the Universal Postal Union, effectively converting cross-border mail from a patchwork of bilateral bargains into a shared system. This is one reason Europe’s postal history matters disproportionately for the world: not because letter writing was uniquely European (it was not), but because Europe played an outsized role in formalising public postal institutions and exporting standards—stamps, tariff logics, service definitions, and international conventions—that still structure global postal exchange . Scholarship on epistolary culture also suggests a particularly dense European tradition of letter-writing as a social practice across the late medieval and early modern periods—letters functioning as tools of governance, commerce, and intimacy . At its core, the universal postal system worked because it was built on trust and predictability: a letter posted in one town should arrive in another without the sender negotiating the route, verifying the carrier, or demonstrating identity to multiple intermediaries . In that sense, post belongs to the same family as other infrastructures—roads, power, water—because it quietly encodes distributional questions: who is easy to reach, who counts as a full participant, and whose communications are treated as worth the cost. American sociologist Susan Leigh Star’s work helps explain why Denmark’s postal changes have felt socially charged. Star argues that public infrastructures are typically experienced as invisible—embedded in routine and taken for granted—precisely because they function reliably in the background. When a system is withdrawn or degraded, its social significance becomes legible: people can see what it was doing, what it made easy, and what daily life had been organised around . Postal systems fit this pattern closely. Universality is rarely noticed in periods of stability, it becomes salient when substitution becomes necessary and its costs become uneven. This is where concerns about rural residents, older populations, recent migrants, people with limited mobility, and those with low digital confidence tend to concentrate. Over time, universality functions as a form of social insurance: it reduces the transaction costs of basic participation. As the network is pared back, those costs re-emerge in practical ways—distance to drop-off points, reliance on apps, reduced frequency, and higher prices—and they re-emerge most sharply for those already facing constraints . Against this backdrop, Denmark has simultaneously produced a striking counter-signal: a 2025 survey reported that 18–34-year-olds in Denmark send roughly two to three times as many letters as older age groups . The implication is not necessarily a future volume rebound; it points more plausibly to a shift in the meaning and role of the letter itself. One theory for this change draws on scarcity and signalling. When a behaviour becomes rare, it can gain value as a marker of effort, taste, and sincerity. In marketing terms, physical mail moves away from mass reach and toward attention quality . In cultural-economic terms, it begins to resemble an artisanal good: slower, more expensive per unit, but richer in perceived authenticity . For instance: Postcrossing, an online platform that matches people to exchange postcards worldwide, reports that over 84 million postcards have been exchanged through the project to date . Its annual statistics suggest the practice is not marginal: in 2024 alone, users registered about 5 million received postcards. This points to a clear interest in handwritten, slow mediums of communication . It is possible that the spread of AI-generated text may intensify this dynamic. As writing becomes easier to produce at scale, audiences may place greater value on “human traces” that are difficult to replicate convincingly—handwriting, idiosyncratic phrasing, and the physical residue of someone’s time . Psychology offers a complementary perspective: a handwritten letter is not only a message, it is also a cognitive and affective artefact . Research in neuroscience and psychology even suggests handwriting engages memory and learning differently from typing through motor involvement and deeper encoding, in part because it is slower and more effortful. In a culture oriented toward speed and volume, the letter’s slowness can perform care. Evidence beyond Denmark is mixed, but the underlying appetite for letters among younger groups is not uniquely Danish. A UK poll publicised by Amnesty International found that 18–34-year-olds were more likely than older adults to say they wished they received more letters, and more likely to regret not keeping letters from the past . This suggests a generational pull toward analogue forms of connection even in highly digital lives. More broadly, as text becomes abundant, copyable, and increasingly auto-generated, credibility and presence become harder to establish through content alone. Letters address that problem in a distinctive way by anchoring communication in time, effort, and materiality. The strongest caution against romanticising this “luxury attention” future is that the costs of postal withdrawal are not evenly distributed. Denmark’s new arrangements rely on app-mediated purchasing and shop-based drop-off (or paid pickup), which—while workable for many—create additional friction for those with limited mobility, weak digital confidence, or long travel distances. Across the EU, the distributional issue is structural: Eurostat estimates that only 56% of people aged 16–74 had at least basic digital skills in 2023, meaning a large minority lacks the baseline competence assumed by digital-first transitions . Europe also has evidence that removing postal touchpoints can provoke rural backlash; reportage in France on the surprise removal of village postboxes describes anger linked to perceived withdrawal of basic services from peripheral communities . If letters drift toward lifestyle niche status, policy questions about minimum access and territorial cohesion become more acute. Whether handwritten mail will “come back” depends on the definition of comeback. DAO expects to scale letter volumes from roughly 30 million letters in 2025 to around 80 million in 2026, explicitly linking this to a youth-driven revolt against digital saturation . Their plan is to innovate the postal service in its current form, in order to lean in to this renewed popularity. DAO seems to believe that letters can still be re-developed, catering to young people, through service design, convenience, and branding, even as the broader system pivots toward parcels. However, a return to twentieth-century mass letter volumes is unlikely in Denmark and Europe given the structural dominance of digital messaging and the reorientation of postal operators toward parcels. What is plausible is a bifurcation: letters decline as routine infrastructure, while persisting (or even growing) as a niche practice with high cultural value—especially among younger cohorts using analogue forms to manage digital fatigue, perform authenticity, and create durable personal archives in an era of ephemeral feeds. Denmark, by dismantling the most visible symbols of everyday mail, may end up clarifying this split for the rest of Europe—showing not only what is lost when universal delivery recedes, but also what kinds of meaning letters can still accumulate. Ultimately, Europe must decide whether post universality is worth preserving: as an inclusive infrastructure, a tool of connection, and as a form of cultural inheritance. Shall we?
