The disposable dataset, by the numbers
A daily snapshot of the canonical list behind our detection engine, merged from many public sources and our own Mail Exchange (MX) harvesting. We publish the shape of the data, not the list itself.
Registrable roots, e.g. mailinator.com
A label deeper, e.g. mail.mailinator.com

across 668 TLDsApex vs subdomain
What is an apex domain? It is the registrable root of a name, like mailinator.com. Anything with an extra label in front (mail.mailinator.com) is a subdomain. We track both, because throwaway providers spin up subdomains too.
