Verifies an email address and its domain with DNS-based risk checks
Verifies an email address and its domain with DNS-based risk checks: MX, disposable-domain, role-account, SPF, DMARC, and DKIM signals. Privacy-safe: does not probe the recipient mailbox. Use it as an email verifier, email verification API, or to validate email address deliverability.
