Hi Product Hunt 👋 Every email verifier hits the same wall: some mail servers say "yes" to every address (catch-all domains), so nobody can confirm whether the mailbox really exists. Yet most tools still charge you full price for that "catch-all" result. We thought pricing should match what you actually get, so ListCheckup refunds catch-all and unknown results. What you get: • A clean list ready to import • Your original file with a status, score and reason for every address • A PDF report you can share with a client or your team Pricing is pay-as-you-go: from €5 for 1,000 checks to €149 for 100,000, and credits never expire. There are 100 free checks every month, so you can try it on a real list today. I'd love your feedback, especially from cold email and agency folks: how do you handle catch-all addresses today?
