parked_domain

The domain's nameservers belong to a parking service

The domain is parked or for sale and still accepts mail, so whoever collects that mail is not your customer.

risk weight: +60
dataset: parking-nameservers
reads from: parked
verdict reason: parked_domain

What it means

The nameservers match the bundled parking list — Sedo, ParkingCrew, Bodis, Afternic, Dan and their kind. The check runs only when the domain has usable mail servers, because a parked domain with no MX is already undeliverable, and null means the nameserver lookup failed rather than a clean answer.

It reads from the parked field and comes with the parked_domain verdict reason, placed after a typo-squat and before disposable.

What to do

Treat it as a harvesting address: do not send, and offer a correction only when did_you_mean carries one. The default sending policy blocks on it.

Example response

{
    "email": "[email protected]",
    "deliverable": "risky",
    "reason": "parked_domain",
    "parked": true,
    "risk_signals": [
        {
            "signal": "parked_domain",
            "weight": 60,
            "dataset": "parking-nameservers"
        }
    ]
}

Abbreviated: a real answer carries all 46 fields, listed in the verify-email reference. The risk_signals entry shown is the one this signal adds; the weights of every entry in the list sum to risk_score.
