Public result model

E8Y returns one of three statuses: valid, risky, or invalid. A reason explains the primary outcome, while classifications add useful context.

{
  "email": "person@example.com",
  "domain": "example.com",
  "status": "valid",
  "reason": "recipient_accepted",
  "provider": "Google Workspace",
  "suggestion": null,
  "classifications": []
}
