DNS

Run SPF, DKIM, DMARC, and MX checks together with a confidence score

Multi-check email-authentication validator: runs SPF/DKIM/DMARC/MX in parallel (or a subset via checks) and returns a combined confidence_score. Use this for a one-call deliverability audit instead of four separate dns/check calls. Rate limit: 10 requests/minute per IP.
