Case study Cosori
AllegroImplementing Allegro One Fulfillment gave a home appliance distributor its competitive edge


About the client
Our client is the official representative and distributor of the Cosori brand across a vast swathe of Europe. Its territory covers the countries east of Germany (excluding Germany itself), as well as most of the Balkan countries. An experienced player in the international home appliance market, the company is responsible for building awareness of Cosori products and for distributing and selling them across many markets with varying potential and momentum. Its global experience and drive to expand speak to the ambition and professionalism it brought to the challenge of entering the Polish market.


The client’s product range
| Product category | Example products |
|---|---|
| Air fryers | single- and dual-basket air fryers |
| Multicookers and multifunction appliances | multicookers, electric pressure cookers, 2-in-1 appliances |
| Other kitchen appliances | small appliances for meal preparation |
| Accessories and parts | baskets, liners and consumables for air fryers |
The industry
Selling small appliances online means competing in one of the most saturated and competitive categories on Polish marketplaces. In recent years, air fryers alone have gone from a niche product to a staple in many kitchens, and with that popularity came dozens of brands – from global consumer electronics and home appliance giants to smaller private labels. Shoppers in this sector rarely type a manufacturer’s name into the search bar: they start with a generic search term, compare a dozen or more listings, read reviews and check the price before they even decide whose product to buy.
This means that in the home appliance industry, results come down to three things: visibility in rankings and product comparisons; trust built through reviews, warranties and after-sales service; and logistics – because selling kitchen appliances online is largely a game of fast delivery and hassle-free returns. Add to that strong seasonality: Black Friday and the run-up to Christmas can account for the lion’s share of a category’s annual sales. A small appliance distributor that wants to stand out therefore has to plan the whole of Q4 several months in advance.
The client’s challenges
During a free consultation, a Cosori representative told us about their sales goals and the challenges they were facing as they expanded:
Cosori’s main goal was not just to launch its products on Allegro, but above all to set a direction for growth and map out a strategic plan for Q4 2024.
With no warehouses in Poland, the client needed an end-to-end logistics solution that would allow orders to be fulfilled smoothly from the very start.
At the time, the Cosori brand was virtually unknown to Polish shoppers on Allegro. Despite its global reputation, in Poland it had to build its position from scratch, with no brand recognition and no established distribution network.
Market analysis
The Polish air fryer market was booming and its potential kept growing, which made it extremely attractive to Cosori. At the same time, this rapid growth meant fiercer competition and the need to act fast. Q4 2024 looked like a now-or-never moment – a crucial window for the brand to make its mark and establish itself in the category before the market became even more saturated. Missing it would have made building awareness and market share much harder in the future. Our challenge as an agency was therefore not only to launch the product, but also to pull off a rapid, effective market entry during the most intense trading period of the year.

What we did
Allegro Fulfillment – the operational and promotional foundation
Allegro Fulfillment solved the problem of the client having no local warehouses. This key implementation not only gave Cosori smooth logistics (warehousing, shipping, returns) and access to Allegro Smart! but also opened the door to Allegro’s exclusive promotional campaigns. As a result, the brand’s flagship product made it into the elite Black Week promotional category, which significantly boosted its visibility and price appeal.
An aggressive awareness-building strategy
To make the Cosori logo and its air fryers stick in shoppers’ minds quickly, we relied heavily on Allegro Ads, focusing on the visual side of the brand. We began preparing for Q4 as early as Q3 2024, and towards the end of that quarter we stepped up our advertising, including display campaigns. During this period we also launched a new flagship product – the Cosori TwinFry – which became the centrepiece of our messaging.

Allegro Ads
We used:
- Sponsored Offers: visually showcasing products and the logo in strategic spots across Allegro.
- Banner ads: reaching a wide audience through banners on the homepage and category pages.
- Template ads: dynamically presenting specific models and their unique features, driving traffic to optimised listings.
Product page optimisation
In a category as saturated as small appliances, it is the product page that tips the balance when shoppers compare a dozen or more very similar listings – which is why we build it around the phrases buyers actually search for (“air fryers”, “oil-free fryers”, “multicookers”) and around the selling points that dispel any doubts before purchase: capacity, features, warranty and service.
The aim was to harness Allegro’s full potential to quickly make the Cosori brand known and trusted, while also supporting sales during the busiest time of the year.

What we achieved
Q4 2024 – market entry
Our first quarter of work closed with a turnover of PLN 843k and a place near the top of the ranking of air fryer sellers on Allegro – all for a brand that had been virtually absent from Poland just a few months earlier.
The chart shows a steady rise in financial results, which accelerated markedly in Q4. The quarter peaked in November, when sales exceeded PLN 400,000 – confirming the effectiveness of our efforts during this period.

Market position
Thanks to a strategic approach and precise execution, we successfully launched Cosori’s operations on Allegro, building brand awareness almost from scratch. After just one quarter of work, the Cosori brand reached 7th place* in the Q4 ranking of air fryer sellers on Allegro by sales value.
* We run two Cosori brand accounts on Allegro – one of them ranked 9th, but with both accounts combined, total sales rise to almost PLN 900,000, which translates into 7th place in the Allegro ranking.

Q4 2025 – scaling up
Compared with the previous Q4, we increased turnover from PLN 843k to PLN 1.693m. We applied exactly the same strategy as a year earlier and managed to hold on to the same market position. Despite selling in the premium segment, we feature among the top 10 sellers on Allegro. Set against other sellers, the disparity between our number of transactions and our sales value is especially telling – proof that we are selling an entirely different class of appliance.

December turned out to be the peak month – nearly PLN 780k – and on its own came close to the result for the entire quarter a year earlier.

Value for the client
Our comprehensive strategy allowed Cosori to enter the Polish e-commerce market at lightning speed without having to invest in its own logistics infrastructure, while giving sales a flying start and building brand recognition at a crucial time. We delivered not only sales but also a solid operational and strategic foundation for the brand’s further growth in Poland – the best proof of which is that the result was repeated, and doubled, the following season.
What’s more, the spectacular success achieved on Allegro significantly accelerated and strengthened the overall promotion of the Cosori brand in Poland. Thanks to our work, the Cosori brand caught the attention of the Polish market, and today – on the back of the results achieved and the visibility built – our client supplies its products to the largest retailers in Poland, such as Media Expert, Euro RTV AGD and Neonet. This confirms that strategic, effective work on Allegro can be a catalyst for a brand’s wider nationwide expansion.
