deliverability-qa

deliverability-qa is a skill for Claude Code from aaron-he-zhu/aaron-marketing-skills. It costs 198 tokens per session (3,688 once invoked), scanned A, original, Apache-2.0.

A one-time check of email-sending setup before a campaign is sent, including authentication records, reputation, inbox placement, message content, links, rendering, and list hygiene.

In plain words
What is it for?
Use it to check SPF, DKIM, DMARC, BIMI, bounce and complaint rates, and prepare a pre-send checklist for a chosen sending domain and email type.
Why use it?
It identifies delivery or spam risks before they affect a real send. It also shows which checks are incomplete instead of treating missing evidence as a pass.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

deliverability-qa scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Deliverability QA

One-time pre-flight snapshot before a send — authentication, domain/IP reputation, inbox placement, a spam-content/link/render scan, and point-in-time list hygiene — delivered as a per-qualified-item Pass/Partial/Fail/Unknown/N/A read plus an S1 authentication evidence flag. Emit the SEND S (Sender-integrity / Deliverability) dimension score only at 100% applicable coverage; otherwise return NEEDS_INPUT/UNDECIDED/NOT_SCORED and the exact gaps. This is the pre-send snapshot, not the standing watch owned by list-hygiene-monitor. Scope guard: this skill builds and, when complete, scores SEND-S, and runs the S1 authentication pre-flight only; it does NOT compute the profile-weighted EQS or enforce the S1/S2/N1/D1 vetoes — that is email-quality-auditor.

Quick Start

Run a deliverability pre-flight for [sending domain] before I send. Here is my DMARC RUA report, a DNS export, and my seed-list inbox-placement test: [paste/path].
Check my SPF/DKIM/DMARC/BIMI and my bounce + spam-complaint rates, then give me a pre-send checklist I can run myself. ESP: [name]. Profile: [promotional / retention / cold-outbound / newsletter].
Why am I hitting the Promotions tab / spam? Here is my inbox-placement seed test and ESP deliverability report — score my SEND S and flag S1.

Skill Contract

Expected output: a deliverability pre-flight (Pass/Partial/Fail/Unknown/N/A per qualified item), an S1 authentication evidence flag (pass / partial / veto-candidate / unknown), a spam-content/link/render scan, a list-hygiene read, the typed profile, and either a complete-coverage SEND S score or NEEDS_INPUT/UNDECIDED/NOT_SCORED with exact gaps, plus the standard handoff summary.

  • Reads: sending domain + SEND profile (promotional|retention|cold-outbound|newsletter); a DNS export of SPF/DKIM/DMARC/BIMI records; the DMARC aggregate (RUA) report; a seed-list / inbox-placement test (inbox vs spam/promotions); the ESP deliverability report and sending-domain/IP reputation (Postmaster / SNDS); the campaign/creative HTML for the content/link/render scan. Consult consent-registry for S2 list-consent context only — leave the S2 verdict to the auditor.
  • Writes: a user-facing pre-flight report plus a reusable SEND-S summary to memory/email/deliverability-qa/.
  • Promotes: deliverability blockers (auth failing/unaligned, no DMARC record, reputation degraded, inbox-placement below threshold, bounce/complaint over benchmark) and the SEND-S score to memory/hot-cache.md and memory/open-loops.md; propose durable auth/domain decisions as pending-decision items — do not write decisions.md directly.
  • Done when: every applicable S item is Pass/Partial/Fail/Unknown/N/A with evidence or a gap reason (never pass-by-default); the S1 evidence flag is pass, partial, veto-candidate, or unknown; the scan and hygiene read are stated; and the typed profile emits an S score only at complete applicable coverage, otherwise NEEDS_INPUT/UNDECIDED/NOT_SCORED with no score.
  • Primary next skill: email-quality-auditor to score the full EQS and enforce S1/S2/N1/D1 once S is verified.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
