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.

Test it

Using "inbox-placement-monitor". Gmail inbox 88%, promotions 10%, spam 2%; Outlook inbox 72%, junk 28%; no prior baseline.

Expected outcome:

Placement is mixed. Gmail is inbox-dominant, while Outlook needs attention because 28% reached junk. No delta is available, so this run becomes the baseline. Yahoo and Apple are NEEDS_INPUT.

Using "inbox-placement-monitor". Yahoo inbox fell from 96% to 71%. Gmail reputation changed from High to Medium, and spam rate rose from 0.08% to 0.14%.

Expected outcome:

Placement is degrading. Yahoo inbox placement fell 25 points. Gmail reputation declined, and spam rate crossed the 0.1% red line. Review sender authentication and reputation setup next.

Using "inbox-placement-monitor". Gmail, Outlook, Yahoo, and Apple placement stayed within two points. SNDS remained green with no trap hits.

Expected outcome:

Placement is holding. No provider shows a material regression, and Microsoft IP reputation remains stable. Save this snapshot as the next baseline.

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.

The line documents a Python connector command whose --live option sends seed emails through Resend. Dry-run defaults reduce exposure, but the outbound side effect is real.

What You Can Build

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.

Try These Prompts

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.

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.

Avoid

  • 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.

Frequently Asked Questions

What data should I provide?
Provide seed-test placement by provider, Gmail Postmaster exports, Microsoft SNDS exports, ESP delivery data, and a prior baseline when available.
Can the skill access my provider dashboards directly?
It primarily analyzes exports or pasted results from your accounts. Optional connectors may automate collection when separately configured.
Does this skill send test emails?
It can reference a Resend seed-send helper. The helper is dry-run by default and requires explicit confirmation before --live sending.
Does it check SPF, DKIM, or DMARC?
No. Use a deliverability preflight workflow for authentication checks, then use this skill for post-send placement trends.
What happens when a provider is missing?
The provider is marked NEEDS_INPUT. The skill does not assume a pass or invent a placement rate.
What happens when there is no prior send?
The skill reports current placement without a delta and records the complete run as the next comparison baseline.
