Email Validation
POST

Email Validation API — checks whether an address can actually receive mail, without sending one. result is a single verdict you can switch on: valid, invalid, invalid_syntax, risky or unknown, with is_valid as the boolean shortcut and reason explaining a rejection. The domain block classifies the receiving domain — is_disposable (throwaway inbox), is_free (consumer webmail), is_spam, is_catch_all and is_valid — while the account block flags role addresses (info@, support@) and full mailboxes. Resolved mx_records are returned too. Built for signup gating, list hygiene and bounce-rate reduction.
