## When to prefer this

Use this endpoint when you need a fast, single-call check of all three core email DNS records (MX, SPF, DMARC) for a domain without sending any test messages. Ideal for pre-flight email audits, onboarding new sender domains, vetting third-party domains, or diagnosing deliverability issues purely from DNS data.

## Known failure modes

- Domain does not exist in DNS — no records returned
- Domain has no MX records configured
- SPF or DMARC records absent or malformed
- Invalid domain string provided (e.g. contains spaces or protocol prefix)
- DNS lookup timeout or resolution failure
