Validates email addresses against RFC 5322 syntax, checks MX records via live DNS, detects disposable domains from a list of over 121,000 known providers, flags role-based addresses, suggests corrections for common domain typos, classifies the domain type, and normalizes addresses for de-duplication. Each request returns a weighted risk score and a deliverability verdict. The API is stateless and stores no submitted data.
Authentication is handled by the marketplace gateway, so no key management is required in your own code.
Risk scores are computed from weighted flags: invalid syntax scores 100 and short-circuits all other checks, no MX record adds 55, an MX timeout adds 30, a disposable domain adds 75, a role-based address adds 20, a typo adds 10, and a free provider adds 5. The total is capped at 100. The deliverability verdict is derived from the score: high for 0 to 20, medium for 21 to 49, low for 50 to 79, and undeliverable for 80 to 100.
Domain type is classified in precedence order: disposable, then free, educational, government, ISP, and finally business. When passing an email address that contains a plus sign in a query string, the plus must be percent-encoded as %2B, since an unencoded plus is interpreted as a space and will fail syntax validation.
No. It validates syntax, confirms the domain can receive mail through a live MX record lookup, and scores reputation signals such as disposable domains, role-based addresses, and typos. It does not perform live SMTP mailbox verification, so it cannot confirm that a specific mailbox exists. The deliverability verdict and risk score are strong indicative signals, not a delivery guarantee
Each detected flag adds weighted points. No MX record adds 55, an MX timeout adds 30, a disposable domain adds 75, a role-based address adds 20, a typo adds 10, and a free provider adds 5. Invalid syntax scores 100 and skips all other checks. The total is capped at 100, and the deliverability verdict is derived from it. High is 0 to 20, medium is 21 to 49, low is 50 to 79, and undeliverable is 80 to 100.
Disposable or throwaway domains are temporary email services such as Mailinator and ten-minute-mail providers, commonly used to bypass signup gates. The API checks against a list of over 121000 known disposable domains. You can check a single domain with the disposable endpoint or export the full list with the disposable list endpoint.
It runs in two stages. First it checks an exact map of common misspellings of the top providers, which returns high confidence. If there is no exact match, it compares the domain against the known provider list by edit distance, and a single-character difference returns the closest match at medium confidence. If neither stage matches, no suggestion is returned.
A free provider is an independent webmail service such as Gmail, Yahoo, or Outlook. An ISP type is a mailbox bundled with an internet or telecom subscription such as Comcast, BT Internet, or Orange. Both are non-business addresses, and the distinction is useful for analytics and for filtering business signups.
Yes. The batch validation endpoint accepts up to 50 email addresses in a single request and returns a result for each one plus a summary of counts across the batch. There is also a batch domain endpoint that accepts up to 100 domains.
No. The API is stateless and uses no database. Email addresses and domains you submit are processed in memory to produce the response and are not retained. The only data loaded is the static list of disposable domains, providers, and typo mappings.
In a URL query string an unencoded plus sign is read as a space before the API receives it, and a space is not valid in an email address, so the request fails validation. Encode the plus sign as %2B and it will be received correctly.
Cada punto final devuelve datos JSON estructurados. Por ejemplo, el punto final de Validar Correo Electrónico proporciona campos como correo electrónico, válido, sintaxis, mx, desechable, rol, proveedor gratuito, sugerencia de error tipográfico, tipo de correo electrónico, capacidad de entrega y puntaje de riesgo. Los puntos finales por lotes devuelven campos similares para múltiples correos electrónicos o dominios, junto con estadísticas resumidas
Los campos clave incluyen "email" para la dirección revisada "valid" que indica si es válida "risk_score" que refleja el riesgo de entregabilidad y "deliverability" que categoriza la probabilidad de que el correo electrónico llegue a las bandejas de entrada Campos adicionales brindan información sobre la sintaxis los registros MX y el tipo de dominio
Parameters vary by endpoint. For instance, the Validate Emails Batch endpoint accepts a JSON body with an "emails" array, while the Check Syntax endpoint requires an "email" query parameter. Users can customize requests by providing specific email addresses or domains as needed.
Response data is organized in a JSON format with a "success" boolean, a "data" object containing the results, and a "meta" object with disclaimers. Each result includes relevant fields like email validity and risk assessment, making it easy to parse and utilize.
The API uses a combination of live DNS lookups for MX records, a static list of over 121,000 disposable domains, and a typo map for common misspellings. This multi-source approach enhances data accuracy and reliability for email validation.
Typical use cases include validating email addresses during user sign-ups, cleaning email lists for marketing campaigns, and assessing the quality of leads. Businesses can use the risk score and deliverability verdict to prioritize outreach efforts.
Users can leverage the risk score and deliverability verdict to filter out high-risk emails before sending campaigns. The typo suggestions can help correct common mistakes, while the classification of email types aids in segmenting audiences for targeted marketing.
Data accuracy is maintained through regular updates to the disposable domain list and typo mappings, along with real-time DNS checks for MX records. This ensures that the API provides current and reliable information for email validation tasks.
