Causal, a provider of advanced digital advertising solutions, has announced a strategic partnership with OpenX, an omnichannel supply-side platform, to deliver impactful and sustainable connected TV (CTV) advertising at scale.
In a recent campaign advocating for expanded access to affordable healthcare in New York, the collaboration delivered measurable success, driving a 17.73% increase in efficiency compared to other SSPs tested.
OpenX’s transparent marketplace has consistently helped Causal clients achieve meaningful results across verticals, including political advocacy.
For this initiative, the campaign strategy emphasised broad reach, controlled frequency, and contextual alignment. OpenX accounted for 36% of total impressions, delivered primarily through premium CTV placements on both national and local news programming.
This quality-first approach ensured high-impact delivery without over-saturation, reinforcing advocacy messaging with maximum resonance.
