Quality-check a B2B lead list (CSV) before a cold outreach campaign. Finds duplicate contacts, invalid, role-based, free-mail and disposable emails, email domains that do not match the company, domains with no mail server, missing fields, the seniority mix and companies with too many contacts, and gives a score out of 100. Use when someone shares a lead list, a CSV export from Apollo, Clay, Sales Navigator or a CRM, and asks if it is ready to use or why it bounces.
