Case Study: How we acquired over 250 new customers for one of the largest mobile operators in Poland

by | Apr 30, 2025 | Case Study

In the dynamically changing world of performance marketing, the key to success is the precise alignment of strategy with client needs and the effective use of data. In April 2025, our agency was approached by a company serving one of the largest mobile operators in Poland. The goal was clear: to acquire new customers for phone subscriptions along with devices. The client expected quick and measurable results, and we were ready to meet the challenge. Thanks to a strategic approach, advanced targeting and campaign optimization, we not only achieved our goals, but also significantly exceeded them, delivering more than 250 sales and generating impressive performance metrics. In this article, we outline how we achieved this success step-by-step and why our client decided to continue our cooperation.

The ideal customer and their needs

Our client is a company that has been operating for years as a partner of one of the leaders of the telecommunications market in Poland. It handles the sale of mobile subscriptions, both for individual and business customers, offering attractive packages with devices such as smartphones and tablets. In April 2025, the client set an ambitious goal: to increase the number of new subscribers through a spring promotional campaign. It was crucial to reach people who are ready to switch operators and interested in buying a new device bundled with a subscription. The client expected the campaign to be not only effective in terms of the number of leads acquired, but also cost-effective, with a clear return on investment. With our experience in performance marketing and access to a unique database, we were able to design a campaign that perfectly met these needs.

The database at our disposal has proven to be a key asset. It contains information about users who, in our online forms, declared their interest in switching mobile operators. These are people who are actively looking for better deals, are open to new solutions and are ready to make a purchase decision. Such precise segmentation allowed us to focus on a group with high conversion potential, which significantly increased the effectiveness of the activities. The client appreciated our data-driven approach, which allowed us to minimize budget dispersion and focus on the most promising audiences.

Strategy and operations

To achieve our goals, we designed a multi-channel campaign based on two pillars: email marketing and SMS marketing. The choice of these channels was not accidental. Email marketing allowed us to provide detailed information about the offer, including the benefits of the new subscription and available devices. SMS marketing, on the other hand, provided quick and direct outreach, succinctly communicating the key elements of the promotion and encouraging action. The two channels complemented each other, creating a cohesive purchase path that led recipients from initial contact to the completion of the transaction.

Email marketing: personalization and engaging content

As part of the email campaign, we prepared a series of messages that were fully personalized based on data from our database. Each recipient received an offer tailored to their preferences, such as an offer for a smartphone at a certain price or a subscription with more mobile data. The content of the emails was concise but engaging, with a clear call to action (CTA) and an attractive design that highlighted the benefits of the offer. A key element was the use of dynamic banners that showcased the devices available for the promotion. In addition, we implemented automatic follow-up sequences for people who opened the message but did not take action, which helped increase conversions.

Email marketing results exceeded expectations. We achieved an Open Rate (OR) of 9%, meaning that 9% recipients opened our messages. Click-Through Rate (CTR) was 13%, indicating that 13% people who opened the email clicked on the link leading to the offer page. Finally, the Conversion Rate (CR) reached 1,24%, which means that 1,24% recipients who clicked on the link made a subscription purchase with the device. To better illustrate these results, let's analyze the numbers: if we sent 100,000 emails, about 9,000 people opened the message, 1,170 clicked on the link, and 145 of them finalized the purchase. These numbers confirm that precise targeting and engaging content translated into real results.

SMS marketing: speed and efficiency

In parallel, we ran an SMS campaign to quickly reach the recipients and encourage them to take advantage of the offer. SMS messages were short, containing key information about the promotion (e.g. "New smartphone + subscription from PLN 49/month. Check it out now!") and a link to a landing page. This page was optimized for mobile devices, which ensured convenient form filling and purchase finalization. As with emails, SMS messages were personalized, such as including the recipient's name, which increased their effectiveness.

The SMS campaign also yielded excellent results. The high CTR confirmed that recipients were eager to go to the offer page, and the smooth purchase process on the landing page contributed to high conversions. The combination of SMS and email allowed us to reach recipients at different points in their purchase path, which significantly increased the chances of completing the transaction.

Results that speak for themselves

In total, the campaign generated more than 250 sales of new subscriptions with devices, which significantly exceeded the client's expectations. Performance metrics such as 9% OR, 13% CTR and 1,24% CR confirmed that our efforts were not only effective, but also precise. Every element of the campaign - from database segmentation to message personalization to landing page optimization - was designed to maximize results. Importantly, the campaign was also cost-effective, allowing the client to achieve a high return on investment.

Summary

The success of this campaign is proof that performance marketing based on data and precise targeting can yield spectacular results. Thanks to our unique database, strategic approach and use of email and SMS marketing, we delivered more than 250 new subscribers to the client, achieving excellent performance indicators. The client, satisfied with the results, decided to continue the cooperation in the following months, which is the best confirmation for us of the quality of our services.

This case demonstrates the importance of understanding a client's needs and tailoring activities to the specifics of their business. At our agency, we focus on transparency, measurability and continuous optimization, which allows us to deliver results that exceed expectations. If your company also wants to achieve similar successes, contact us - together we will design a campaign that will take your business to a new level.

 

How we helped a B2B client increase fuel card sales

How we helped a B2B client increase fuel card sales

by | Sep 9, 2024 | Case Study

Our client is a dynamically growing company that has specialized for years in providing modern fuel card solutions aimed at B2B companies. This well-established company serves a broad spectrum of clients, from small and medium-sized enterprises to large corporations for whom optimization of fuel costs is a key element of financial management.

The client approached us with a clear need to increase sales of its products, noting the increasing competition in the industry and the changing needs of its customers. One of the main challenges we faced was to reach a wider group of potential customers who could benefit from the advantages of the fuel cards offered. Our client wanted not only to increase the number of cards sold, but also to build lasting relationships with new business partners, which could result in long-term benefits for both parties.

In response to these needs, we worked with the client to develop a comprehensive marketing strategy that took into account both the specifics of the industry and the unique needs of its customers. We focused on precise targeting and the use of modern communication tools, which yielded significant results, which we will discuss later in this article. Thanks to this strategy, we were able to not only meet our goals, but also exceed our client's expectations, resulting in further cooperation.

 

Determine the profile of the ideal customer

 

The first and extremely important step in our cooperation was to precisely define the profile of the ideal customer. We knew that precisely defining our target group would allow us to be more effective in our marketing efforts and achieve our goals. In the process, it was crucial to understand which companies could benefit most from the fuel cards offered by our client, and then focus on those with the greatest potential to purchase them.

First of all, we focused on companies that have fleets of company vehicles. These were primarily transportation, logistics and construction companies, where fleet management is a daily challenge. For these companies, the ability to use fuel cards was not just a convenience, but a necessity that allowed better control of fuel expenses and improved operational processes.

Another key criterion was high fuel demand. We identified that companies that regularly use a lot of fuel can significantly reduce their operating costs with fuel cards. In particular, we paid attention to companies for which the price of fuel is an important part of the budget, and any savings translates into improved profitability for the entire business. Fuel cards, offered by our client, were not only a tool for these companies to control expenses, but also a way to increase financial efficiency.

A final, but equally important aspect was that these companies should had B2B structures. We understood that B2B companies regularly needed to manage fuel costs, as well as optimize operating expenses. For such companies, our fuel cards provided an ideal solution that made it easy and fast to account for fuel expenses, as well as provide additional benefits such as discounts and loyalty programs.

With such a detailed profile of the ideal client, we were able to target the companies that had the greatest potential to benefit from our client's offer. This allowed us not only to increase the effectiveness of the campaign, but also to maximize the return on investment, which in turn translated into the satisfaction of both our client and his new business partners.

 

Marketing strategy 

 

Having precisely determined the profile of the ideal client, we proceeded to implement a campaign that aimed to maximize the potential of the identified target groups. We knew that the key to success would be the proper selection of communication channels and the adaptation of the message to the specifics of each market segment. Therefore, we decided to focus our activities on two key areas: e-mail marketing and SMS marketing.

As part of e-mail marketing, we targeted personalized e-mails to a carefully selected database of companies that met the established criteria. Each e-mail was precisely tailored to the recipient, taking into account the specifics of their industry and individual needs. In the content of the e-mails, we emphasized the most important benefits of using fuel cards, such as saving time and money, the ability to effectively manage a fleet and full control over fuel costs. We made sure that the message was clear and understandable, while at the same time arousing interest and motivating people to take action. In addition, the emails contained visually appealing elements, such as graphics and infographics that presented the main advantages of the offer in an accessible way.

In parallel with the e-mail campaign, we also decided to use the SMS channel to reach decision-makers in companies. We knew that in certain industries, where quick response counts, short and specific SMS messages could be particularly effective. The SMS messages contained a concise but precise message with an offer and a link to quickly purchase a fuel card. This allowed recipients to immediately go to the purchase page, significantly shortening the decision-making process and increasing the chance of conversion. The SMS channel proved to be extremely effective, especially for companies that prefer fast and direct forms of communication.

Thanks to the synergy of these two channels, we were able to not only reach a wide range of potential customers, but also effectively motivate them to take advantage of the offer. The combination of personalized e-mail marketing with dynamic and direct SMS marketing allowed us to achieve our goals, and the results of the campaign confirmed that it was a strategy well suited to our client's needs.

 

Campaign results

 

Our activities produced tangible and very satisfying results that not only met, but in many respects exceeded our client's expectations. The focus on precise targeting and skillful use of selected communication channels resulted in impressive results in a relatively short period of time.

In just one month, we were able to generate as many as 20,000 clicks to the fuel card website. This number translates into a huge amount of traffic to the site, which provided a solid basis for further conversion efforts. Such a result confirmed that our strategy of reaching a well-chosen target group was effective, and that our message hit the needs of potential customers.

Equally importantly, we were able to maintain our cost per click (CPC) at PLN 1.4, which is an extremely competitive rate in the context of the B2B industry. Achieving such a low CPC testifies to the high efficiency of our advertising campaigns, which were well optimized from a cost perspective, while maximizing the value of each click. As a result, our client was able to enjoy not only high website traffic, but also a favorable cost-to-results ratio.

However, the most important indicator of the success of our campaign was the number of fuel cards sold. Within a month, we managed to sell more than 200 cards, which not only met but even exceeded the client's original expectations. Such a result not only confirmed the effectiveness of our activities, but also built a strong foundation for further long-term cooperation. For us, the customer's satisfaction with the results achieved was the best proof that our strategy was well adapted to their needs and expectations.

The success of the campaign was the result of the synergy between precise targeting and effective use of selected communication channels. Focusing on the right tools and strategies allowed us to effectively reach the target group, which translated into real sales results. Our cooperation with the client, based on trust and a professional approach, resulted not only in great results, but also in the further development of our business relationship.

 

Summary

 

Thanks to our cooperation, the client achieved its goals, and we were able to enjoy another successful project. The results achieved made the client decide to continue working with our agency, which for us is the best confirmation of the effectiveness of our activities.

This case study shows how important it is to choose the right marketing tools and precise targeting to achieve the desired goals. We are pleased that we were able to help the client achieve success and look forward to further joint projects.
