Instantly Campaign Health Monitor

Daily AI health monitoring for your Instantly outbound campaigns — scores deliverability, engagement, domain reputation, sequence fatigue, and ICP response divergence.

Daily AI health monitoring for your Instantly outbound campaigns — scores deliverability, engagement, domain reputation, sequence fatigue, and ICP response divergence. Four-agent pipeline: Fetcher pulls campaign analytics from Instantly V2, Assembler computes rolling metrics, Analyst scores 5 CHS dimensions with chain-of-thought reasoning, Formatter delivers Slack daily digest and Google Sheets health dashboard rows. AGGREGATE pattern — one analysis per daily run, not per campaign. Split-workflow: weekday 8:00 UTC schedule + manual webhook. Critical alerts fire when CHS drops below threshold or domain reputation degrades.

Four Agents. Campaign Health Scoring. Slack + Google Sheets Delivery.

Fetcher

Step 1 — Fetcher

Code Only

Pulls campaign analytics from the Instantly V2 API for each configured campaign. Retrieves send counts, bounce rates, spam complaints, open rates, reply rates, opt-outs, and domain health indicators. Zero LLM cost.

Assembler

Step 2 — Assembler

Code Only

Computes five CHS dimension metrics per campaign: deliverability score (bounce + spam rates), engagement trajectory (open/reply trends), domain reputation risk (warmup status + health), sequence fatigue (opt-out rates + step count), and ICP response divergence (segment variance). Pure math. Zero LLM cost.

Analyst

Step 3 — Analyst

Tier 2 Classification

Scores each CHS dimension 1-10 using defined rubrics, computes composite CHS (equal 20% weight), classifies HEALTHY/DEGRADED/CRITICAL, generates per-campaign health insights, and flags critical alerts. Sonnet 4.6 with chain-of-thought enforcement.

Formatter

Step 4 — Formatter

Tier 3 Creative

Generates two outputs: (1) Slack Block Kit daily digest with per-campaign health scores, dimension highlights, and critical alerts. (2) Google Sheets row data for historical health dashboard tracking. Sonnet 4.6.

What It Does NOT Do

×

Does not send or modify Instantly campaigns — it reads analytics only, never writes

×

Does not replace your email ops team — it provides daily health signals for human decision-making

×

Does not work with Mailgun, SendGrid, or other ESPs — Instantly V2 API only in v1.0

×

Does not predict future deliverability — it scores current campaign health from existing data

×

Does not guarantee inbox placement — it identifies degrading campaigns for proactive intervention

×

Does not manage domain warmup — it monitors warmup status as one dimension of domain reputation

Frequently Asked Questions

What is a Campaign Health Score (CHS)?+

CHS measures the overall health of an Instantly outbound campaign across 5 dimensions: deliverability (bounce/spam rates), engagement trajectory (open/reply trends), domain reputation risk (sender health), sequence fatigue (opt-out rates and step count), and ICP response divergence (segment-level variance). A composite score of 1-10 classifies campaigns as HEALTHY, DEGRADED, or CRITICAL.

What are the five CHS dimensions?+

Deliverability Score (bounce and spam rates vs inbox placement), Engagement Trajectory (open and reply rate trends), Domain Reputation Risk (sender domain health and warmup status), Sequence Fatigue (opt-out rates and sequence length vs decay), and ICP Response Divergence (response rate variance across prospect segments).

When do critical alerts fire?+

When any campaign scores at or below the CHS_CRITICAL_THRESHOLD (default: 4) or when domain reputation score drops to or below DOMAIN_ALERT_THRESHOLD (default: 3). Critical alerts are sent as a separate Slack message in addition to the daily digest.

How does it relate to the Autonomous SDR?+

The SDR sends outbound sequences via Instantly. The Campaign Health Monitor watches the infrastructure health of those campaigns. SDR creates. ICHM monitors. Different tools, complementary purposes.

Why Google Sheets instead of Notion?+

Google Sheets provides better support for time-series data tracking. Each daily run appends a row, building a historical health dashboard you can chart and analyze. Notion is better for rich documents; Sheets is better for tabular metrics.

Why only Sonnet instead of Opus?+

The Fetcher retrieves campaign data from the Instantly V2 API and the Assembler pre-computes all CHS metrics. The Analyst receives pre-computed numbers and applies a scoring rubric — classification-tier reasoning that Sonnet 4.6 handles accurately. No deep causal analysis required.

Can I customize which campaigns to monitor?+

Yes. Set CAMPAIGN_IDS to an array of specific Instantly campaign IDs, or leave as empty array to monitor all active campaigns. You can also adjust CHS_CRITICAL_THRESHOLD, DOMAIN_ALERT_THRESHOLD, GOOGLE_SHEET_ID, and SLACK_CHANNEL.

Does it use web scraping?+

No. All data comes from the Instantly V2 API. No web_search or external scraping. Fully deterministic and fast.

How often does it run?+

Every weekday at 8:00 UTC by default (Monday through Friday). The schedule is configurable in the scheduler workflow. You can also trigger it manually via webhook at any time.

Is there a refund policy?+
