Get Over 50% Fewer Bounces
Generic verifiers discard catch-all domains but often miss invalid addresses that still cause bounces. Listmint verifies them in real time to deliver cleaner, safer lists.
Proof of Results: 84% Valid vs 55% Industry Average
Generic verification tools confirm only about 55% of records, leaving bounce risks in your database. Listmint customers see up to 84% valid results, which consistently keeps bounce rates below 1%.
