Why we give these away
Most email-verification companies hide everything behind a signup wall. We don't. Our paid product runs full SMTP probes for 99% accuracy at $0.008 per email — but for the 80% of cases you can solve with DNS and a good disposable list, these free tools are all you need. Use them as much as you want.
When to upgrade to MailoClean
- → You need 99% accuracy with live SMTP mailbox-exists verification (not just MX-record check).
- → You want to verify lists over 25 emails — our paid bulk handles 50,000+ per batch.
- → You need an API to verify emails on signup, lead-capture, or CRM sync.
