disposable

The domain belongs to a disposable, temporary email provider

What it means

Spaw syncs the open disposable-provider list weekly and extends it with local overrides, and it also matches the operators behind a domain's MX hosts, so a fresh burner domain on a known disposable backend is caught before the list catches up. Whoever signed up with a disposable address does not expect to hear from you again.

Disposable domains are never sent to the mailbox probe, so smtp_checked is false. The risk weight of 80 puts the address in the high band by itself.

What to do

For signups, block the address or ask for a different one. For existing lists, do not send: even when the message is accepted nobody reads it, and these domains attract spam-trap conversions.

Example response

{
    "email": "[email protected]",
    "deliverable": "risky",
    "reason": "disposable",
    "disposable": true,
    "smtp_checked": false,
    "risk_score": 90
}

Abbreviated: a real answer carries all 27 fields, listed in the verify-email reference.
