# `disposable`: the domain belongs to a disposable, temporary email provider

The domain, or the mail infrastructure behind its MX hosts, is on the open disposable-provider list. The inbox exists for minutes or hours.

- Appears in: `reason`
- Verdict: risky
- Risk weight: +80
- Billing: 1 credit, like every deliverable or risky answer. Repeats of the same address are free for 7 days.

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.

```json
{
    "email": "x9@mailinator.com",
    "deliverable": "risky",
    "reason": "disposable",
    "disposable": true,
    "smtp_checked": false,
    "risk_score": 90
}
```
