Validate email addresses and assess their reliability through a comprehensive set of checks covering syntax, domain configuration, mail server availability, and potential risk indicators. This API evaluates whether an email address follows standard formatting rules, whether its domain exists, and whether valid Mail Exchange (MX) records are configured to receive email.
Each response includes an overall validation result, a numerical confidence score, and a verdict indicating the assessed status of the email address. The API also provides individual check results, allowing applications to identify specific validation conditions, including syntax validity, domain existence, MX record availability, disposable email usage, role-based addresses, and free email provider identification.
When available, the response includes the domain's MX records, helping developers inspect the mail routing configuration associated with the submitted address. A suggested correction may also be returned when an alternative email address is identified.
This API is suitable for registration forms, customer onboarding, lead validation, CRM systems, marketing platforms, and data quality workflows. It helps businesses identify potentially unreliable email addresses before storing or processing them.
