Get Over 50% More Valid Customer Contacts
Most tools discard catch-all corporate domains where your key users work. Listmint verifies them in real time, letting you keep more customers engaged and prevent churn.
Proof of Results: 84% Valid vs 55% Industry Average
Other verifiers only return about 55% valid contacts, leaving nearly half of your users out of the loop. Listmint customers see up to 84% valid results, which means more engagement and higher retention rates.
Real-Time API for CRM and Success Tools
Verify customer contact data at the point of entry in your CRM or customer success platform. This keeps account records accurate from day one.
