How to use this list

In B2B applications, emails from free providers (gmail.com, yahoo.com, etc.) typically indicate personal accounts rather than business ones. Use this list to flag or filter non-business signups.

For real-time classification with additional context (provider name, custom domain detection, confidence score), use the EmailKind API.

curl -H "Authorization: Bearer sk_live_YOUR_KEY" \
  "https://emailkind.com/v1/[email protected]"

// Response includes:
// "provider": { "name": "Gmail", "type": "personal" }
// "classification": { "is_free": true, "is_business": false }
