Cold outreach is one of the most effective ways to start conversations with prospects, but bad email data can ruin your sender reputation, waste SDR time, and tank reply rates.
Validate corporate decision-maker emails that generic tools mark as “unknown.”

Clean lists instantly so SDRs and founders can start campaigns the same day.
7-Step Verification Process
Includes SMTP, DNS, MX, and pattern analysis for maximum accuracy.
Built for Scale
Perfect for high-volume outreach campaigns and multi-rep sales teams.
Protect Your Domain While Sending Cold Emails
Cold email campaigns are fragile — one bad list can get your domain blacklisted. Verified lists keep bounce rates low and deliverability high.

Get Over 50% More Valid Prospects
Other verification tools discard catch-all domains that often include your best prospects. Listmint verifies them in real time so you can safely widen your funnel and increase meetings booked.
Proof of Results: 84% Valid vs 55% Industry Average
Generic verifiers confirm only about 55% of contacts, meaning half your outreach goes nowhere. Listmint customers see up to 84% valid results, which leads to better reply rates and more pipeline.
Real-Time API for List Enrichment Tools
Connect Listmint to LinkedIn scraping tools, enrichment platforms, or CRMs to verify prospects the moment they’re added to your outreach lists.
Avoid Bounces and Protect Deliverability
Keeping bounce rates under 1% protects your domain from being flagged, ensuring your campaigns stay deliverable as you scale volume.
