Case studies

  • JourneyDXP is a pioneer in digital customer experience with their innovative "Smart Rooms" integrated with SalesForce. After 17 months of collaboration with Belkins, their dynamic strategies secured 126 appointments, achieving all set KPIs and generating 19,390 leads, an average of 8-10 monthly appointments. Especially effective was targeting innovation titles, leading to their highest appointment conversion rate.
  • Belkins helped YorkTest, a leader in home-to-laboratory tests and wellness consultancy, break into the U.S. market, achieve a 95% customer satisfaction rate, and book 5 appointments per month. YorkTest initially faced challenges entering the U.S. market due to limited research capacity. Belkins’ strategies included targeting HR professionals and employee benefits managers, focusing on brokers but later shifted to HRs in innovative sectors like software development and digital marketing. We implemented hybrid outreach campaigns combining cold email and LinkedIn strategies. These resulted in around 3,000 broker leads and 1,500 HR leads in the first three months and were followed by an additional 3,000 HR leads. The campaigns achieved a 50% cold email open rate and 3–5% response rate, leading to the company’s first closed deals in the U.S. market.

Client’s voice:

The exceptional quality of their leads is impressive! We needed dedicated sales reps who could help us set appointments with large healthcare organizations. Belkins had to target pretty niche specialists in large corporations. We gave them the list of leads to reach, but soon they started their own research. Their campaign was successful. As we often visit conferences, Belkins came up with the idea to communicate with participants of those events, and this approach also brought us leads. In addition, Belkins offered to re-engage the existing clients as we ran out of leads at some point.
