Frequently Asked Questions
How accurate is Hunter.io email verification?
+
Hunter.io provides 95%+ accuracy for email verification when using Advanced verification level. Basic verification only checks pattern matching (70-80% accuracy), while Standard adds MX and SMTP checks (85-90% accuracy). Advanced verification includes catch-all detection and disposable email filtering for maximum reliability.
What email patterns does Hunter.io detect?
+
Hunter.io detects common patterns like {first}.{last}@domain.com, {first}{last}@domain.com, {f}{last}@domain.com, {first}@domain.com, and more. It analyzes publicly available emails from the domain to determine the most common pattern. Confidence scores above 80% are highly reliable.
Can I use Hunter.io for cold email legally?
+
Yes, but with restrictions. Hunter.io sources emails from public data, which is legal. However, YOUR use must comply with GDPR (EU), CAN-SPAM (US), and CASL (Canada). Always: 1) Have legitimate interest, 2) Provide clear opt-out, 3) Honor unsubscribe requests within 10 days, 4) Include physical address, 5) Avoid false subject lines. B2B cold email is generally allowed, B2C is heavily restricted.
What’s the difference between email finding and verification?
+
Email Finding: Hunter.io guesses emails based on detected company patterns. Verification: Confirms if the email actually exists without sending. Finding is predictive (uses patterns), verification is diagnostic (checks servers). Always verify before cold emailing to avoid high bounce rates that damage sender reputation.
How many Hunter.io credits do I need per month?

Budget 1 credit per email search + 1 credit per verification. For 500 cold emails/month: 1000 credits total. Free plan: 25 searches/month. Starter ($49): 500 searches. Growth ($149): 5,000 searches. Business ($399): 50,000 searches. Always add 20% buffer for re-verification and bounces.
