Case Study: DenizBank achieves 56% lower acquisition costs while maintaining sales volume with Adjust

DenizBank lowers cost-per-acquisition with Adjust

DenizBank, one of Turkey’s most innovative private banks and the creator of mobile products like fastPay and MobilDeniz, faced rising user-acquisition costs after initially running broad, high-volume ad campaigns. The bank needed to narrow its targeting and comply with GDPR and banking regulations while still reaching the right customers without overspending.

By integrating Adjust trackers across apps and unpaid channels (SMS, email, push) and using Adjust’s Audience Builder to create and exclude dynamic groups from paid retargeting (via direct Facebook integration), DenizBank separated paid vs. unpaid users without sharing sensitive data. This approach cut total ad spend by 56%, maintained sales volume from paid channels, and allowed much more efficient budget allocation.
