# Deliverability QA 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** read over time is [list-hygiene-monitor](../list-hygiene-monitor/SKILL.md)'s, so only one skill owns the standing trend-read. **Scope guard: this skill scores SEND-`S` and runs the `S1` authentication pre-flight only; it does NOT compute the goal-weighted EQS or enforce the `S1`/`S2`/`N1`/`D1` vetoes — that is [email-quality-auditor](../../deliver/email-quality-auditor/SKILL.md).** It is the `S1` prerequisite (the deliverability signal the auditor rolls up), the same way conversion-signal-qa is the `R1`/`R2` prerequisite for paid and campaign-architect scores one dimension and hands off — build/verify the signal here, let the gate render the verdict. ## 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/DKI...
