In 2026, lead quality determines revenue efficiency more than ever. Marketers face rising costs and low conversion rates, with many leads failing to progress due to poor qualification, invalid data, or mismatched intent. This creates pressure to prioritize signals of buyer readiness over sheer volume.
Buyers demand personalized, timely engagement, while sales teams reject up to 80% of leads as unqualified. Invalid contacts and lack of nurturing exacerbate the gap, pushing teams toward AI-driven scoring and aligned definitions of quality.
