Vendor claims such as large customer counts or coverage percentages require methodological clarity (definitions, geographies, provider mix, validation method, bounce rates). Prospective purchasers should request customer references and quantifiable pre/post metrics.
Recommendation for procurement teams: Request one or two customer references in the same segment, and ask for before/after reply rates, meeting rates, pipeline attribution, data validation statistics (bounce and incorrect contact rates), and a mapping of credit consumption to cost per qualified lead.
