Deliverability Qa includes pricing or quota commentary; at least one code block. At roughly 1,652 words the SKILL.md is on the longer end of the catalog distribution.
Deliverability Qa sits in the General category under the general-misc sub-topic in the ClaudSkills catalog. There are 10 related skills indexed alongside it; comparing a few before installing usually reveals which fits your workflow best.
A free static scan flagged 1 of ten categories (filesystem), including lower-severity patterns. Read the security scan below before installing — a pattern inside a code fence is weighted as an example, not an instruction.
Installing Deliverability Qa writes its SKILL.md to ~/.claude/skills/deliverability-qa/SKILL.md; Claude Code discovers it automatically on the next session — no restart flag needed. It declares no allowed-tools restriction, so it inherits your session’s existing tool access rather than narrowing it. To confirm it loaded, ask Claude to list its available skills — deliverability-qa should appear by name.
There are 10 related skills in General — a two-minute scan of the alternatives usually confirms whether Deliverability Qa is the right pick.

One-time pre-flight snapshot before a send — authentication (SPF/DKIM/DMARC/BIMI alignment from a DNS lookup + the DMARC aggregate/RUA report), sending-domain/IP reputation, inbox placement vs spam/promotions (seed-list test), a spam-content/link/render scan, and a point-in-time list-hygiene read (bounce + spam-complaint rates) — delivered as a per-sub-item pass/partial/needs-input read plus the SEND S (Sender-integrity / Deliverability) dimension score and an S1 authentication status flag. This is the pre-send snapshot, not the standing watch: the recurring hygiene / bounce-complaint trend…
Deliverability Qa is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/deliverability-qa/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when the user asks to "run a deliverability pre-flight before I send", "check my SPF/DKIM/DMARC/BIMI", "why am I landing in spam / promotions", or "score my sender reputation and list hygiene"; runs the ONE-TIME pre-send SEND S1 authentication pre-flight and scores the SEND S (Sender-integrity / Deliverability) dimension — a DNS + DMARC-RUA auth check, domain/IP reputation read, inbox-placement (seed-list) result, a spam-content/link/render scan, and a point-in-time bounce/complaint list-hygiene snapshot — with per-sub-item pass/partial/needs-input notes and an S1 status flag. Not for the recurring hygiene / bounce-complaint trend read over time — use list-hygiene-monitor; not for computing the final EQS or enforcing the vetoes — use email-quality-auditor; not for building segments/suppression lists — use list-segment-builder.
The Deliverability Qa Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 196,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
