Poland’s neighbourly relations once resembled family ties, built on communist-era life where shared housing blocks, communal courtyards and neighbourhood committees meant people relied on each other daily. Post-1989, as Poland embraced the free market, these connections deteriorated and neighbours grew distant. More recently, rising rents driving frequent moves, and the arrival of 1.5 million Ukrainian neighbours due to the war, have put further strain on community ties. Today, despite 93% of Poles valuing strong neighbourly relations, only a third actively maintain them.
Milka decided to address this directly — putting its core value, tenderness, to work and helping rebuild neighbourly relations in Poland, using the simplest thing it had: a chocolate bar.
The strategy was straightforward: to spark genuine, positive interactions in neighbourhoods, always initiated by a chocolate bar. The campaign took shape through “Hi Hangers” and “The Nameplates Revival,” each targeting a different barrier to connection. Every activation was built around a ‘hinge moment’ — a naturally occurring, everyday situation where a first introduction should happen but rarely does. These barriers included very frequent relocations that hinder building relationships, and widespread anonymity in Polish neighbourhoods. The platform shifted social behaviour at scale — and delivered record commercial results for the brand.
“Hi Hangers”: turning moving day into a tender welcome
4.3 million Poles change address every year. Moving day is chaotic and disorienting — but it’s also the one moment in adult life when introducing yourself to neighbors feels completely natural. You’re new. You have a reason. The silence that builds over months hasn’t had time to form. Milka partnered with Poland’s 15 largest moving companies to be there first. Instead of traditional media placements, surprise packages were placed inside moving vans, found by new arrivals as they unpacked.
Each package contained a Milka chocolate bar and a specially designed door hanger, providing a gentle, no-pressure tool for new arrivals to introduce themselves to their neighbors. The activation extended across the full moving journey, reaching people at every stage: from searching for a new home to carrying in the last box.
Results:
- 22% of all Poles who moved during that period used Hi Hangers across the country
- The integrated campaign platform reached 88% of the adult population
- Digital placements on Otodom.pl, Poland’s largest property portal, achieved a 15% CTR — three to four times the market average
- Geo-targeted push notifications to shoppers at Castorama buying moving supplies achieved a 9.4% CTR
“The Nameplates Revival”: giving neighbours back their names
20% of Poles don’t know the name of a single neighbour. Research pointed to a specific reason: door nameplates — once a standard feature of Polish apartment buildings — had quietly disappeared after 1989. Without a name on the door, there was no obvious way to begin.
Milka brought the tradition back. The brand worked with Jarosław Wojdak — a craftsman who had spent 45 years making these plates for buildings that had long since stopped ordering them. His story became the heart of the campaign. Milka produced 50,000 packages placed directly on apartment doors across seven Polish cities, each containing a personalised nameplate and a Milka bar to share with the person next door. People noticed them — and used them. Tens of thousands hung their nameplate on their door and left a bar of Milka for the neighbor they had never met.
Results:
- The documentary film about Wojdak’s story generated 5 million views on social and digital channels
- National television covered the story organically, reaching a further 3 million people without any paid placement
- The activation reached 21 million people in total
- 3.7 million incremental limited-edition bars sold out entirely
Three years of tenderness: a campaign with lasting impact
Starting in 2024 with 100,000 deliberately misdelivered packages — each containing two Milka bars and a reason to knock on a neighbour’s door — the platform moved through Hi Hangers and The Nameplates Revival, building on what came before. Year-round advertising kept the idea present between activations, always placing Milka in neighbourly scenarios. Every limited-edition bar in circulation was a small extension of the same platform.
The outcomes across three years:
Cultural shift: The share of Poles reporting zero neighbour interaction fell from 35% to 29%. The helpfulness index rose from 19% to 26%. Milka became the #1 brand associated with neighbourhood initiatives in Poland.
Brand: Brand Equity Index rose 11 points. Meaning index grew from 118 to 125. Occasion repertoire expanded from 9.0 to 9.9. The platform reached over 27 million Poles — 96% of the adult population — and generated over 380 million views.
Commercial: Value share grew from 27.4% to 30.5% — a level no competitor had previously reached. 14.27 million incremental limited-edition bars sold out across all three packaging runs.
