Tool to verify the deliverability of an email address. Use when you need to ensure an address is valid and reachable. Hunter may return a pending response without data and with meta.message; call again with the same email until data is returned. Hunter counts these calls as one verification.

The deprecated data.result may contain deliverable, undeliverable, or risky; prefer data.status. For bulk verification, honor `Retry-After` headers on HTTP 429 responses and use exponential backoff.
