Example prompt: Can you run a full email deliverability audit on sendgrid.com and tell me its score, grade, and what's failing — SPF, DMARC, DKIM, the works?

## When to prefer this

Choose this endpoint when you need a single-call, consolidated email deliverability audit covering SPF, DMARC, DKIM, MTA-STS, BIMI, and MX in one response with a normalized score and grade. Prefer it over individual DNS lookup tools when the goal is a holistic deliverability health assessment rather than a single record check. Particularly well-suited for vendor vetting workflows, pre-campaign sender audits, or diagnosing spam folder issues, where a plain-English summary alongside the raw data saves interpretation time.

## Known failure modes

- Domain does not exist or has no DNS records — returns empty or error result for individual checks
- Domain has no email infrastructure (no MX records) — checks that depend on live mail servers may return absent/unknown
- Rate limiting or DNS timeout during selector enumeration — some DKIM selectors may be reported as untested
- Invalid domain input — may return validation error or null results
- DMARC/SPF records malformed but present — tool reports them as found but flags policy weakness

## How this service works

Email authentication and deliverability report for a domain in one call: SPF (with -all check), DMARC policy strength, DKIM presence across common selectors, MTA-STS, BIMI and MX, combined into a 0-100 score with an A-F grade and plain-English findings. Vendor vetting and sender-setup audits. $0.01 per domain.

## Output

Returns a structured report containing: a 0-100 deliverability score, an A-F letter grade, individual check results for SPF (including -all enforcement), DMARC policy strength, DKIM presence across common selectors, MTA-STS, BIMI, and MX records, plus plain-English findings summarizing what is configured correctly and what needs to be fixed.
