Signal-led results
Syntax, domain, MX, SMTP, catch-all, disposable, role, and provider evidence remain separate and visible.
PRIVATE EMAIL INTELLIGENCE
Know what is deliverable—without pretending uncertainty is proof.
Verify one address or process a complete CSV/XLSX list with transparent signals, honest Unknown results, and private local processing.
Private by design
Files stay in private Docker storage, downloads require your browser session, and expired jobs are removed automatically.
Honest uncertainty
MX records alone never become Valid or Catch-all. When mailbox evidence is unavailable, the result is Unknown.
