Email Quality Auditor

Audit one email program/profile and observation window with SEND. Open rate is MPP-sensitive proxy evidence; direct action and the program's declared outcome truth set carry the outcome read.

When This Must Trigger

• Before a material broadcast/sequence release when channel safety is uncertain.
• When authentication, consent, suppression, complaints, frequency, claims, or attribution need a gate.
• When the user requests an EQS/SEND baseline or rerun.

Quick Start

Audit this newsletter using the last 90 days, provider split, MPP share, and subscription truth set.
Check this promotional send against DMARC, consent events, live suppressions, claims, and order IDs.

Skill Contract

Reads: one program/profile, normalized window, provider evidence, live consent/suppression state, rendered messages, and outcome truth. Writes: only a permissioned v3 artifact. Done when: all expected SEND states are explicit and the scorer result is reported without sending email or changing provider settings.

Use deliverability-qa to repair authentication, consent-registry for lawful-basis/suppression facts, email-sequence-designer for journeys, and send-experiment-designer for preregistered tests.

Data Sources

Need	Preferred evidence
Authentication	DNS, message headers, DMARC aggregate evidence
Consent/suppression	Append-only consent events plus current live projection
Placement/reputation	Provider/seed panel and dated ESP/provider reports
Engagement	Cohort/provider/MPP-segmented ESP export
Lifecycle	Trigger/flow configuration and event export
Outcome	Ecommerce, CRM, subscription, sponsorship, or named equivalent truth set
Content	Rendered message/destination and approved claim/disclosure state

Instructions

Runtime Reads

• ../../../references/auditor-runbook.md
• ../../../references/scoring-semantics.md
• ../../../references/send-benchmark.md
• ../../../references/runtime-invocation.md
• references/auditor-runtime.md

Runtime and Setup

Read ../../../references/auditor-runbook.md, scoring-semantics.md, send-benchmark.md, and the SEND catalog entry. Standalone installs use bundled immutable references/auditor-runtime.md; never fetch mutable main. Before deterministic calls, follow runtime-invocation.md, resolve AARON_SKILLS_ROOT="${CLAUDE_PLUGIN_ROOT:-$(git rev-parse --show-toplevel 2>/dev/null || true)}", and require the scorer, validator, and typed catalogs. If unavailable, return score_state: NOT_SCORED / score_confidence: not_scored with no gate verdict or persistent artifact.

Declare profile (promotional|retention|cold-outbound|newsletter), target/program, provider, market, normalized window, list age, MPP share, and observation date.

Evidence and Scoring

1. Freeze evidence and reconcile provider cohorts/windows before comparing rates.
2. Score all 20 S1..D5 criteria. Every observed state requires source/date/type/confidence.
3. E2 is N/A with reason when opens/CTOR are not used. N3/N5 are conditional by program design. Missing records or exports are Unknown, not N/A.
4. Verify vetoes:
   • SEND-S1: required authentication is demonstrably broken/unaligned.
   • SEND-S2: a purchased/scraped/unlawful list is verified; missing provenance is Unknown.
   • SEND-N1: opt-out is broken/absent or a recorded suppression is not honored.
   • SEND-D1: material claim/disclosure/offer term fails approved evidence.
5. Run the typed scorer. Use clicks/replies/downstream actions as primary engagement evidence where available; opens/CTOR remain caveated proxy evidence.

For a send-only review without enough program evidence, report the verified red-line checks and exact gaps but return NOT_SCORED/UNDECIDED; “no blocker observed in supplied evidence” is not a full SEND SHIP verdict.

§2 SEND Worked Examples

• Complete newsletter profile, raw 81, no veto/fail: DONE/SHIP, final 81.
• Complete promotional profile, raw 76, one verified S1 failure: DONE_WITH_CONCERNS/FIX, final 59.
• Complete profile, verified S2 and N1 failures: DONE/BLOCK, no final score.
• Consent provenance absent: S2 Unknown, NEEDS_INPUT/UNDECIDED, no score.

§3 SEND Guardrails

• DMARC p=none with aligned SPF/DKIM and active monitoring is not automatically an S1 failure.
• Provider one-click-unsubscribe policy and statutory duties must be named separately.
• Opens and CTOR require MPP segmentation/proxy caveat; they cannot establish human attention alone.
• A newsletter need not have cart/post-purchase flows; score only journeys applicable to its declared program.
• Over-frequency is a serious E4/E5 finding, not an automatic veto.

§5 SEND Translation

Explain channel and recipient risk in plain language. On trace request, qualify SEND-S1/S2/N1/D1 and show the underlying DNS/event/rendered evidence.

Report and Verdict

Begin with the auditor-runbook's exact typed conversation header. Never replace status, verdict, or score_state with prose; list each explicitly missing qualified item as ``ID: `unknown``` before findings.

Show verdict, profile/context, score or coverage/interval, confidence, S/E/N/D detail, outcome truth set, verified critical controls, Unknown inputs, and fix owners. Do not claim deliverability/inbox placement from DNS alone and do not execute a send.

Validation Checkpoints

• Program/profile/provider/window/list age/market/MPP share are declared.
• Live suppression state was verified by replay, not a stale projection or pending proposal.
• All 20 states are valid; conditional N/A has a reason.
• Provider metrics and reconciled outcome truth are separated.
• No email/provider mutation occurred without separate explicit approval.

Persistence

Persist only after explicit authorization to memory/audits/email/YYYY-MM-DD-<topic>.md. Preserve the scorer's orthogonal status and verdict; validate the complete v3 draft with validate-audit-artifact.py against the intended --relative-path, persist only through one full-content Write, and revalidate the target per the auditor runbook. Edit/shell/MCP mutations of the reserved sink are unsupported. Do not autonomously modify consent, claims, provider settings, or hot cache.
