# Monitor Email Inbox Placement and Sender Reputation

Mailbox placement can shift after every campaign, while provider dashboards and seed tests remain fragmented. This skill combines your exports into provider trends, deltas, and clear follow-up actions.

## Capabilities

- Reads provider-level inbox, spam, promotions, and other placement from user-supplied seed-test results.
- Summarizes Gmail Postmaster domain reputation, IP reputation, spam-rate, and feedback-loop trends.
- Summarizes Microsoft SNDS IP status, complaint-rate, volume, and spam-trap trends.
- Compares current and prior sends, naming each provider regression and its magnitude.
- Labels metrics as measured, user-provided, or estimated and marks missing providers as NEEDS\_INPUT.
- Produces a reusable SEND-S placement snapshot for downstream deliverability review.

## Use Cases

- Diagnose a campaign placement drop: Compare the latest seed test with the prior send and identify which mailbox providers regressed.
- Track sender reputation across providers: Combine Gmail Postmaster and Microsoft SNDS exports into a directional reputation and complaint-rate trend.
- Establish a post-send baseline: Record provider placement after a migration, warming change, or new campaign strategy for future comparisons.

## Prompt Templates

### Review one seed test

```
Review this seed-test result for [domain]. Report inbox, spam, and promotions placement by provider. Mark every missing provider as NEEDS_INPUT.
```

### Compare two sends

```
Compare these current and prior seed tests for [domain]. Name every provider regression, show its magnitude, and state whether placement is holding.
```

### Combine placement and reputation

```
Analyze these seed-test, Gmail Postmaster, and Microsoft SNDS exports. Connect placement changes with domain reputation, IP status, complaints, and trap hits.
```

### Build a rolling deliverability trend

```
Trend these [N] sends for [domain] using the [profile] profile. Identify recurring provider regressions and prepare a reusable SEND-S placement handoff.
```

## Limitations

- Requires user-provided seed tests, dashboard exports, or pasted telemetry; it cannot infer missing placement data.
- Does not run SPF, DKIM, or DMARC preflight checks and does not calculate the full Email Quality Score.
- Cannot compute send-over-send change without a prior baseline; the first complete run becomes that baseline.
- Seed-list results represent tested mailboxes and do not guarantee placement for every recipient.

## Best Practices

- Use the same seed addresses and measurement method across sends so comparisons remain meaningful.
- Provide complete exports and label each reporting period, domain, IP, provider, and sending profile.
- Confirm before any live seed send, and verify every recipient belongs to the intended seed list.

## Anti Patterns

- Do not treat a missing mailbox provider as passing; mark it NEEDS\_INPUT.
- Do not infer a send-over-send change when no prior baseline exists.
- Do not use this skill as a replacement for authentication preflight or full Email Quality Score gating.

## Security Audit

- Audited at: 2026-07-26T10:21:10.442\+00:00
- Summary: One finding is confirmed: SKILL.md documents a Python connector whose --live mode sends seed emails through Resend. The other 54 alerts are Markdown links, code formatting, metadata URLs, or benign monitoring language; no prompt injection was found.
