Disposable email domain check

Paste an address or a domain. The browser removes the part before @ and sends only the domain, which is compared with a disposable-domain list bundled in this service. The list is CC0 1.0. This does not contact a mailbox.

Throwaway domains pass a syntax check and then vanish.
A subdomain of a known disposable domain is the same problem.
A domain that is not on the list can still be undeliverable.

POST /verify/email

Questions

Do you receive the full address?

No. The page sends the domain only. A request that still contains @ is rejected and the value is not repeated.

Which list is this?

A disposable-domain list released under CC0 1.0 and bundled with this service. Subdomains of a listed domain count too.

How do I know the mailbox itself is disposable?

POST /verify/email at $0.01 checks the mailbox and includes a disposable signal from that check.
