[01] How email verification works
Triple-verified before it reaches you.
Not just a pattern match.
MX record validation
We check the domain has a valid mail exchange (MX) record before even attempting delivery.
SMTP handshake check
Andoxa pings the mail server and confirms the mailbox exists, without ever sending a real email.
Catch-all detection
We flag catch-all domains separately, so you know which addresses can't be verified individually.
Disposable and role email filtering
Automatically removes info@, support@ and temporary addresses from your results.
Email pattern inference
When no direct match is found, we infer the likely email pattern from verified addresses at the same company.
Confidence scoring
Every email comes with a confidence score to tier your outreach: high-confidence first, inferred second.
