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.
