Burner domains

Disposable email domains on the brushemail.com mail network

117 domains we track have MX records pointing at servers under brushemail.com. Our harvester classifies the servers below as burner mail hosts. Each serves 3 or more listed burner domains and no allowlisted real mail provider, and was reviewed by hand or is named after a listed burner domain. That is an inference from DNS and the lists. It does not prove that every domain on them is disposable. Our disposable email checker blocks any domain whose mail goes to them, including new domains that no list has yet.
