thoob/email-validator

Validates a list of email addresses: practical RFC 5322 syntax, live domain mail-capability (MX/A over DNS-over-HTTPS), disposable-domain detection, and role-account flags. Honest scope: it checks the address and the domain, not the mailbox. Billed only per address checked.

Generate likely corporate email candidates from a name and domain, then check syntax, MX, disposable-domain, and role-address signals. No mailbox-existence or deliverability guarantee.
