    You say

    Our outbound campaign for example.com dropped from a 4% reply rate to 0.2% starting last Tuesday. We use Instantly. Here is our historical volume and the current DNS setup.

    Your agent does

    Triage complete. The drop correlates with a Spameatingmonkey blocklist entry on two sending IPs after volume spiked to 75 emails/day/inbox.

    Root Cause: Infrastructure (IP Blocklist) Fix: Rotate IPs and cap volume at 40/day. Re-test: Seed accounts now showing 100% inbox placement.

    About this skill

    The problem

    Cold email reply rates often crater without warning. Developers and growth teams waste weeks rewriting copy when the actual issue is a blacklisted domain, broken SPF records, or a specific ISP filtering content.

    What it does

    • Pins the exact drop date from historical volume and reply rate data to isolate the trigger.
    • Runs live infrastructure checks on domains and IP addresses to identify blocklist status or DNS record failures.
    • Performs provider-specific placement testing to determine if content is being filtered by specific mail servers (e.g., Google vs. Outlook).
    • Analyzes list health by evaluating bounce rates, complaint spikes, and the prevalence of catch-all domains.
    • Produces a documented incident report including the root cause, verified fix, and a preventative monitoring check.

    Frameworks & tools

    Uses the domain-deliverability-checker via Apify for live DNS and blocklist data. Integrates with existing BRAND.md context for domain history.

    Why this beats prompting it yourself

    General LLM prompts often hallucinate deliverability advice or jump to copy edits immediately. This skill enforces a technical triage hierarchy that rules out infrastructure and list hygiene before touching content, saving you from burning good domains on bad hypotheses.

    Use cases

    • Identify why a previously high-performing campaign suddenly stopped generating replies.
    • Debug "inbox placement" issues when open rates drop below 20% on established domains.
    • Audit new domain health before scaling up outbound volume.
    • Document a deliverability incident for a client or stakeholder with technical proof of the fix.

    Known limitations

    Requires access to an external deliverability checker for live data. Cannot fix reputation issues instantly as ISP cooldowns are server-side.
