The provided sources don't contain specific information about Million Verifier IP blocking issues. However, IP blocking typically occurs when verification services detect unusual traffic patterns or rate limiting violations. Common solutions include: ** Checking if you're exceeding API rate limits ** Ensuring your requests are properly spaced out ** Verifying your API credentials are correct ** Contacting Million Verifier directly about IP whitelist requirements Are you using Million Verifier through our HTTP API integration or through a different method in your Clay table?

Marko K. if most lookups are failing with that error, your IP is likely rate-limited. Try switching to a fresh IP (VPN or different network) and slow the request pace. You can also reach out to Million Verifier support to get the block lifted

You're correct - IP rate limiting is the most likely cause when 90% of Million Verifier lookups fail with "IP address blocked" errors. Try these solutions: ** Switch to a different IP address (VPN or different network) ** Slow down your request pace to avoid hitting rate limits * Contact Million Verifier directly to request IP whitelist removal Rate limiting occurs when verification services detect unusual traffic patterns, so spacing out requests properly should help prevent future blocks.
