Email Validator
Validate email addresses against RFC 5322 syntax rules. Supports bulk validation.
Email validation checks that an address conforms to RFC 5322 syntax rules. A valid email consists of a local part (before the @), the @ symbol, and a domain (after the @). The local part can contain letters, digits, and special characters like dots, hyphens, and plus signs. The domain must contain at least one dot and consist of valid hostname labels. Note that syntactic validation does not verify whether the mailbox actually exists — for that, an SMTP check or email verification service is needed.
