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…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

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… …

How to install
mdr add aaron-he-zhu/aaron-marketing-skills/inbox-placement-monitor@sha256:b0f49e00e37d220cThe line at the top of this page pins the label v20.2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
