Privacy-first syntax, DNS/MX, disposable-domain, role-account, typo, free-provider, and duplicate screening without SMTP mailbox probing.
The API returns data related to email address validation, including syntax checks, DNS/MX evidence, disposable-domain risk, role-account identification, free-provider status, and potential domain typos.
Key fields include `originalEmail`, `status`, `syntaxValid`, `dnsStatus`, `isDisposable`, `isRoleAccount`, `isFreeProvider`, `riskFlags`, and `invalidReason`, which provide insights into the email's validity and associated risks.
The response is structured in a JSON format, containing a `requestId` and a `result` object. The `result` includes detailed fields about the email address, such as its validity status and various risk flags.
The endpoint provides information on email syntax validity, DNS/MX records, disposable domain status, role account identification, free email provider status, and potential typos, helping assess the quality of an email address.
Data accuracy is maintained through continuous updates and checks against DNS records and known disposable domains. The API does not probe mailboxes, ensuring privacy while providing reliable domain-level hygiene insights.
Typical use cases include validating email addresses during user registration, cleaning email lists for marketing campaigns, and identifying potential spam traps or invalid addresses to improve deliverability rates.
The endpoint accepts a single email address as input. Users should ensure the email is in a valid format to receive accurate validation results. Invalid formats may lead to errors in the response.
Users can analyze fields like `status` and `riskFlags` to determine the email's validity and associated risks. For instance, if `isRoleAccount` is true, it may indicate a generic email that could affect engagement rates.
