Case Study: Growww Digital achieves 461% more newsletter subscriptions with ROI Hunter's Dynamic Creative Optimization

Growww Dynamic Creative Optimization Increased Subscriptions by 461%

Growww Digital, a Hungary-based marketing agency working with ROI Hunter, needed a faster way to handle Bonusz Brigád’s constantly changing monthly promotions. Their challenge was creating relevant ads for different audiences without spending hours on manual A/B testing, while also supporting the client’s goals of increasing voucher sales and growing newsletter subscriptions.

ROI Hunter’s Dynamic Creative Optimization (DCO) feature replaced manual testing with automated creative matching across broad interest-based audiences. By uploading multiple images, titles, and descriptions and letting the platform optimize delivery, Growww Digital achieved a 461% increase in newsletter subscriptions, a 3.6x lift in CTR, and a 46% reduction in CPC.
