Personalized email outreach with LinkedIn & Crunchbase data and Gemini AI review

AI-Enriched Cold Outreach: Research → Draft → QA → Write-back

What this template does

Automates cold email drafting from a lead list by:

1. Enriching each lead with LinkedIn profile, LinkedIn company, and Crunchbase data
2. Generating a personalized subject + body with Gemini
3. Auto-reviewing with a Judge agent and writing back only APPROVED drafts to your Data Table

Highlights

• Hands-off enrichment via RapidAPI; raw JSON stored back on each row
• Two-agent pattern: Creative Outreach Agent (draft) + Outreach Email Judge (QA)
• Structured outputs guaranteed by LangChain Structured Output Parsers
• Data Table–native: reads “unprocessed” rows, writes results to the same row
• Async polling with Wait nodes for scraper task results

How it works (flow)

1. Trigger: Manual (replace with Cron if needed)
2. Fetch leads: Data Table “Get row(s)” filters rows where email_subject is empty (pending)
3. Loop: Split in Batches iterates rows
4. Enrichment (runs in parallel):
   • LinkedIn profile: HTTP (company_url) → Wait → Results → Data Table update → linkedin_profile_scrape
   • LinkedIn company: HTTP (company_url) → Wait → Results → Data Table update → linkedin_company_scrape
   • Crunchbase company: HTTP (url_search) → Wait → Results → Data Table update → crunchbase_company_scrape
     (All calls use host cold-outreach-enrichment-scraper with a RapidAPI key.)
5. Draft (Gemini): “Agent One” composes a concise, personalized email using row fields + enrichment + ABOUT ME block.
   • Structured Output Parser enforces:

     {
       "email_subject": "text",
       "email_content": "text"
     }
     

6. Prep for QA: “Email Context” maps email_subject, email_content, and email for the judge.
7. QA (Judge): “Judge Agent” returns APPROVED or REVISE (brief feedback allowed).
8. Route:
   • If APPROVED → Data Table “Update row(s)” writes email_subject + email_body (a.k.a. email_content) back to the row.
   • If REVISE → Skipped; loop continues.

Required setup
