Free verification tools
9 pages that answer one question each, with no account, no key and no card. They run the same pipeline the API does, against the same open registries and published lists, and every one of them says what its answer does not cover as plainly as what it does.
Email and domain
- Email checkerSyntax, the domain’s live mail servers, and the disposable and role lists — without sending mail.
- MX lookupA domain’s mail exchangers, the provider behind them, and whether it accepts mail at all.
- SPF & DMARC checkerThe authentication records a domain publishes, and what its policy actually enforces.
- Disposable email checkerWhether a domain is a burner mailbox provider, matched against the open lists.
