Outbound Prospecting Agent

Apollo-sourced leads, AI-qualified and personally emailed — zero manual prospecting.

Stop prospecting manually. Let AI find and email your best-fit leads. Apollo sources the leads, three specialized agents research, score, and write personalized outreach, then Gmail delivers — all in one 30-node workflow you own. We built this after an SDR manager showed us the spreadsheet her team used to manually score 200 prospects per week. Three tabs, four data sources, zero consistency between reps.

Last updated February 28, 2026

Cold outbound response rates have dropped below 2% industry-wide as inboxes fill with templated sequences. The teams that maintain response rates above 5% are the ones sending researched, context-specific messages at the right trigger moment. Automated research and personalization at scale is no longer a competitive edge — it is table stakes for pipeline generation.

Four Agents. Apollo to Gmail. Zero Manual Steps.

The Researcher

Step 1The Researcher

Web Intelligence

Goes beyond Apollo data. Runs deep web research on each lead — recent company activity, hiring signals, product launches, funding rounds. Builds the context that makes outreach personal, not templated.

The Judge

Step 2The Judge

Reasoning (Tier 1)

What does The Judge actually decide? Six-criteria Lead Utility Score: ICP fit, seniority match, technographic signals, intent indicators, data recency, and contact quality. Each criterion scored independently with explicit reasoning. LUS ≥ 7 threshold — only qualified leads proceed to outreach.

The Ghostwriter

Step 3The Ghostwriter

Creative (Tier 3)

This step exists because raw data alone is not enough. Three sentences max. Research-hook required — every email references a specific finding from the Researcher. 15 forbidden phrases blocked. Plain text only. No HTML, no images, no tracking pixels. Deliverability over aesthetics.

Gmail Syncer

Step 4Gmail Syncer

Delivery

Without this step, upstream analysis sits idle. OAuth-authenticated Gmail delivery. Rate-limited to protect sender reputation. Plain text format maximizes deliverability. Supports both free Gmail (500 sends/day) and Google Workspace (2,000 sends/day).The Researcher costs more than the Judge — web search injects 30K-40K tokens per call. That is why we publish ITP-measured costs, not estimates.

That's the full pipeline. Here's what it intentionally does NOT do — and why those boundaries exist.

What It Does NOT Do

×

Does not build or manage lead lists — Apollo handles discovery, the workflow handles qualification

×

Does not send via third-party email platforms — Gmail only (OAuth, rate-limited)

×

Does not track email opens or clicks — plain text only, no tracking pixels

×

Does not integrate with CRM — qualified leads are emailed directly, export to CRM separately

With those boundaries clear, here's everything that ships when you purchase.

Frequently Asked Questions

Which CRM does this work with?+

Apollo.io for lead sourcing — no CRM dependency. Leads are discovered via Apollo search, researched, scored, and emailed via Gmail. You can export qualified leads to any CRM separately.

Do I need a paid Apollo account?+

Free tier works — 10,000 search records/month. Enrichment credits vary by plan. The dependency matrix documents exact API usage per workflow run.

Does this work with Google Workspace?+

Yes. Free Gmail (500 sends/day) and Google Workspace (2,000 sends/day) both supported. OAuth authentication — no app passwords required.

How long does setup take?+

Approximately 9 minutes. Import the workflow JSON into n8n, configure 3 credentials (Apollo, Gmail OAuth, Anthropic), set your ICP parameters, and run a test lead.

Will my Gmail get flagged for spam?+

The README includes a warm-up guide. Start with 5–10 sends/day and increase gradually. Plain text format, no tracking pixels, and personalized content maximize deliverability.

Can I customize the ICP criteria?+

Yes. LUS scoring weights, target job titles, locations, company size ranges, and industries are all configurable in the Judge agent’s Set node. The README walks through each parameter.

How is this different from the Autonomous SDR?+

Different source, different delivery, different buyer profile. The SDR takes pre-sourced CSV leads and sends via Instantly. The OPA discovers leads via Apollo and sends via Gmail.

Is there a refund policy?+

All sales are final after download. Review the Blueprint Dependency Matrix and prerequisites before purchase. Questions?
