Our mission
Email verification has a credibility problem: too many tools paper over uncertainty with a confident “valid.” We built CorrectInbox to specialize in the hard case — catch-all Microsoft 365 and Google Workspace domains — and to return a confidence score you can actually trust, even when that means saying “unknown.”
What we stand for
Accuracy over vanity
We return a confidence score and admit “unknown” when we genuinely can't resolve an address — never a guessed “valid” to inflate numbers.
Only legitimate data
No scraping, no purchased or breached lists, no PII harvesting. We work only with data that was collected lawfully.
Billing fairness
We never charge for an “unknown” result or for duplicate verifications. You pay for answers, not guesses.
Privacy by default
GDPR-aware storage and a working data-deletion endpoint. Your contacts' data is handled with care.

We're a small team that cares about getting verification right. If that sounds like you, we'd love to talk.
