This chart from NP Digital reveals a brutally honest truth: marketers trust some channels way more than others when it comes to ROI. Email rides high on confidence, while podcasts and content marketing sit in a red sea of doubt. It’s not just about performance—it’s about measurability, consistency, and the comfort of predictability.
Marketers double down on what they can measure and prove. Email and search provide clear ROI tracking, while channels like podcasts remain fuzzy, making budgets harder to justify. The takeaway: if you can’t prove ROI, expect hesitation from decision-makers.
