What defines the "ROI Leader" Award?
In this category, we highlight a company that has taken a meticulous and data-driven approach to automating direct mail campaigns. It's not just about effortlessly tracking and managing numbers & data, but also about demonstrably achieving a positive return on investment. The "ROI Leader" stands for strategic excellence, consistent testing, and the ability to turn even initially unconvincing results into a complete success.
Why Bergzeit Won
Bergzeit deeply impressed us with their approach to optimizing their birthday campaign. Sometimes, it pays not to give up – and their birthday mailing is the best proof of that.
- The Starting Point: In 2022, Bergzeit first tested automated birthday letters. However, the results were not convincing at the time, and the case was initially shelved. But Bergzeit wasn't ready to settle for that.
- Strategic Reorientation in 2024: Instead of giving up, Bergzeit strategically optimized the concept:
- Target group segmentation was refined.
- Format & design were revised.
- Communication was made more emotional.
- The incentive was chosen to be more attractive.
- The Impressive Effect: Through continuous testing and targeted optimizations, Bergzeit unleashed the full potential of their birthday mailing. What was once an underestimated test run evolved into a top performer among their print mailings and print automations.

The numbers speak for themselves:
- Conversion Rate (Redemption Rate): approx. 7.5%
- ROAS (Return on Advertising Spend): approx. 19
With impressive persistence and data-driven testing, Bergzeit has proven that even an initially unsuccessful concept can lead to success – if one is willing to turn the right screws. For us, this case is a true success story that shows that print mailings are a powerful tool for achieving measurable ROI.
