## Tools (1)

- `validate_emails`: Check up to 10 email addresses: syntax, whether the domain exists and has mail servers (MX), mail provider, disposable, role account (info@, sales@), free provider, likely typo with a suggested fix, domain age, SPF and DMARC. Returns verdict (deliverable_likely/risky/undeliverable/invalid), score 0-100 and reason codes per address. Does not verify that the mailbox itself exists.
