Act on `status`: `valid` is safe to send, `invalid` must not be used, `risky` is accepted but uncertain (catch-all domain, role or disposable address, provider that blocks probing) and `unknown` could not be determined. `score` is a 0-100 confidence value, `reason` explains a verdict that is not plainly deliverable and `did_you_mean` suggests a fix for a likely typo. One credit per address actually probed: duplicates and malformed addresses are free. At most 20 addresses per call: split a longer list into several calls.",
