Email Validator

Operational

Real-time email verification with SMTP checks and disposable detection

api API Docs

API Overview

Our Email Validator API provides deep email verification beyond simple syntax checks. Each request performs DNS MX record lookups to confirm the domain can receive mail, optional SMTP handshake verification to check if the specific mailbox exists, and cross-references against a continuously updated database of disposable and temporary email providers. Results include a confidence score so you can tune your acceptance threshold.
