Email address check without sending mail. Returns syntax validity, the normalised address, whether the domain accepts mail (MX, null MX or address fallback), and flags for disposable, role (info@, support@) and free webmail addresses, with a verdict. Use to validate an address someone gave you. Does not confirm the mailbox exists. Typical response under 1 s. Failed calls are not charged.
