Sonar evidence is advisory. Paid delivery is shown as verified only when paid probes are available; otherwise route estimates use the unpaid handshake as a clearly labeled proxy.

LIVE ENDPOINT METADATA

Email validation for lead lists and signup forms: RFC syntax check, live MX record lookup with the actual mail hosts, disposable-domain detection (8k+ known throwaway domains), role-account flag (info@, sales@, noreply@), and free-provider flag, rolled into a per-address ok/risky/invalid verdict with reasons. Batch up to 25 addresses per call. Domain-level DNS checks only, no SMTP mailbox probe. Keyless.

METADATA PROVENANCE

Source catalog records are retained separately from live endpoint observations. Sonar score, uptime, and latency are advisory metrics. CDP indexing is not inferred from validation.
