🎯 What It Does

Every SaaS product, e-commerce platform, or community site faces the same problem: fake signups from disposable emails. Someone creates a throwaway account with user123@guerrillamail.com, abuses your free trial, and disappears.

This actor solves that by analyzing each email and returning:

• ✅ Disposable email detection — Blocks 500+ temporary email providers (Mailinator, Guerrilla Mail, 10MinuteMail, etc.)
• ✅ Free provider detection — Identifies Gmail, Yahoo, Outlook, and 100+ other free email services
• ✅ Business email validation — Confirms legitimate company domains with valid MX records
• ✅ MX record verification — Checks if the domain can actually receive emails
• ✅ Email provider identification — Detects Google Workspace, Microsoft 365, Zoho, and more
• ✅ Role-based email detection — Flags generic addresses like info@, admin@, noreply@
• ✅ Risk level scoring — Returns low, medium, or high risk classification

🎓 How Risk Levels Work

The actor evaluates multiple signals and assigns one of three risk levels:

🟢 Low Risk (Safe to accept)

• Valid business email with MX records
• Examples: ceo@stripe.com, hello@notion.so
• Free providers like Gmail/Yahoo with valid syntax

🟡 Medium Risk (Review manually)

• Missing MX records
• Role-based emails on otherwise valid domains
• Example: team@startup-without-mx-setup.com

🔴 High Risk (Block or flag)

• Disposable/temporary email providers
• Invalid email syntax
• No MX records + other red flags
• Examples: user@mailinator.com, fake@guerrillamail.com
