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 builds the SEND S (Sender-integrity / Deliverability) evidence read — DNS + DMARC-RUA auth, domain/IP reputation, inbox placement, content/link/render, and point-in-time bounce/complaint hygiene — using Pass/Partial/Fail/Unknown/N/A states and scoring only at complete applicable coverage. Not for the recurring hygiene trend — use list-hygiene-monitor; not for final EQS or veto verdicts — use email-quality-auditor; not for segments/suppression lists — use list-segment-builder. 邮件送达率预检/SPF DKIM DMARC认证/发件域声誉

# 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](../list-hygiene-monitor/SKILL.md). **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](../../deliver/email-quality-auditor/SKILL.md).**

## 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].
```
