## Description

Use when the user asks to "track where my emails are actually landing after I send", "read my seed-list inbox vs spam vs promotions results", "trend my Gmail Postmaster / Microsoft SNDS reputation", or "did placement drop after my last send"; produces a per-provider inbox/spam/promotions placement read, a domain/IP reputation trend from Postmaster + SNDS, a send-over-send delta with named regressions, and a reusable SEND-S placement snapshot on your own exported telemetry. Not for the pre-send SPF/DKIM/DMARC auth pre-flight, use deliverability-qa; not for computing the EQS or running the vetoes, use email-quality-auditor. 邮件收件箱落点监测/收件箱vs垃圾邮件/Postmaster声誉趋势

# Inbox Placement Monitor

Post-send placement telemetry: where mail actually landed per mailbox provider (inbox vs spam vs promotions from a seed-list test), the domain/IP reputation trend from Gmail Postmaster Tools and Microsoft SNDS, and the send-over-send delta with named regressions, delivered as a per-provider placement read plus a reusable SEND **S (Sender-integrity / Deliverability)** placement snapshot, with each number labeled Measured / User-provided / Estimated. This is the *after* half of SEND-`S`: [deliverability-qa](../../setup/deliverability-qa/SKILL.md) verifies the signal *before* a send (auth pre-flight, static reputation, one placement test); this skill tracks what happened *after* it and how reputation moves across sends. **Scope guard: this skill tracks post-send placement + reputation trend and hands off a SEND-`S` placement snapshot; it does NOT run the `S1` SPF/DKIM/DMARC auth pre-flight (that is [deliverability-qa](../../setup/deliverability-qa/SKILL.md)) and does NOT compute the profile-weighted EQS or enforce the `S1`/`S2`/`N1`/`D1` vetoes (that is [email-quality-auditor](../email-quality-auditor/SKILL.md)).** Build/trend the telemetry here; let the gate render the verdict.

## Quick Start

```
Track inbox placement for [sending domain] after my last send. Here is my seed-list test (inbox/spam/promotions per provider) and my Gmail Postmaster + Microsoft SNDS export: [paste/path].
```

```
Trend my sender reputation over the last [N] sends and flag any placement regression. Profile: [promotional / retention / cold-outbound / newsletter]. Prior baseline: [paste/path].
```

```
Did placement drop after my last campaign? Compare this seed test against the prior one and tell me which provider regressed and by how much.
```
