Get Over 50% Cleaner Data to Protect Reputation
Generic verifiers discard catch-all domains but often leave risky addresses that damage reputation. Listmint verifies them in real time so you can confidently scale your sending.
Proof of Results: 84% Valid vs 55% Industry Average
Generic verification tools confirm only 55% of records, leading to bounce rates that harm your domain score. Listmint customers see up to 84% valid results, which helps keep domain health strong.
