Understanding confidence scores
Hunter.io returns a confidence score (0-100) with email results.
- 90-100: Very high confidence. The email is almost certainly correct and deliverable.
- 70-89: High confidence. Run email verification before sending.
- 50-69: Medium confidence. Verify before sending.
- Below 50: Low confidence. The email may be wrong or outdated.
Use a Formula Column to filter out low-confidence results:
IF({{Confidence Score}} >= 70, {{Email}}, "")
Troubleshooting
Find Email returns an email but the confidence score is low. Hunter.io could not confirm the email with a strong signal. Run Verify Email (BetterEnrich) on these results to confirm deliverability before sending.
Enrich Company does not return an email pattern. Not all domains have discoverable email patterns. Hunter.io returns patterns only when it has enough confirmed email data for that domain.
API returns "over the quota". Your Hunter.io plan has a monthly request limit. Check your usage at hunter.io/account/billing. Upgrade your Hunter.io plan or use a different provider for the remainder of the month.
Email finding returns empty for a domain that definitely has employees. The domain may use a custom email server that Hunter.io has not indexed. Try Find Email Using Name and Domain (Apollo) or Find Work Email from Full Name and Company Domain (BetterEnrich) as a fallback.
