EmailValidation API
What EmailValidation API is
EmailValidation API is a REST service for checking email syntax, DNS and MX records, and SMTP reachability. Each validation also checks disposable domains, role-based addresses, typo suggestions, and MX behavior. SMTP verification uses real-time RCPT TO checks and FCrDNS-validated HELO for providers including Gmail, Outlook, and iCloud. Results include a confidence level and reason codes for cases that cannot be verified, such as anti-probe or catch-all servers. Integration uses Bearer authentication and requires no SDK; examples are provided for PHP, Python, Node.js, Ruby, and Go. Typical latency is 80–400 ms per email, while repeated checks of the same email within one hour are stated to return in under 10 ms. Each validation costs one credit, including catch-all and anti-probe checks. Credits do not expire, and the minimum deposit is $29. The service offers web and API access, bulk list upload, and real-time form checks; its asynchronous batch endpoint is described as coming soon. The privacy policy says logs store a SHA-256 hash rather than the email address.
