disposable

The domain is a known burner provider

The mailbox lives at a disposable-address service, so it exists to be thrown away; this is the largest weight there is.

risk weight: +80
dataset: disposable-domains
reads from: disposable
verdict reason: disposable

What it means

The domain — or a parent that hands out subdomains, or the operator its MX hosts route mail through — is on the open disposable-domain list, refreshed weekly, with a curated allow-list and deny-list on top. A relay service (Firefox Relay, SimpleLogin and their kind) is read before that list and never counts here: the relay weight of 5 replaces this one.

It reads from the disposable field and comes with the disposable verdict reason. The mailbox is not probed, so smtp_checked is false and the unverified weight fires beside it.

What to do

Ask for another address at signup; on a list, drop the row. The default sending policy blocks on it.

Example response

{
    "email": "[email protected]",
    "deliverable": "risky",
    "reason": "disposable",
    "disposable": true,
    "risk_signals": [
        {
            "signal": "disposable",
            "weight": 80,
            "dataset": "disposable-domains"
        }
    ]
}

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.
