tested 6 b2b data providers head to head - the difference was huge. I will not promote

Ran the same 500 prospect list through ZoomInfo, Lusha, Seamless.AI , Cognism, LeadIQ, and ContactOut last week. Out of 500 contacts, the match rates ranged from 180 (ContactOut) to 410 (ZoomInfo). But what killed me - when we spot-checked 50 random emails from each provider, accuracy was all over the place. ZoomInfo had the most matches but 14 bounced. Seamless had fewer matches but only 3 bounced. We're a 12-person sales team doing about 2k cold emails per week, mostly targeting VP Sales at series B/C Saa
