Disposable domain list / 33mail.com
Is 33mail.com disposable?
No. 33mail.com is not on the disposable email domain list ContactLint uses, so the API returns disposable: false. That does not prove the domain is safe; new throwaway domains appear constantly, and forwarding alias services are not on the list because they forward to real inboxes.
