Disposable email
Ten-minute inboxes people use to get past your form.
Disposable providers (Mailinator, YOPmail, and hundreds of rotating domains) issue burner inboxes that expire in minutes. A signup with one signals someone wanted your lead magnet, not your relationship.
They inflate list size, rot instantly, and drag deliverability down — the classic silent list-decay source.
