Automated Lead Research & Outreach Pipeline (n8n + NeverBounce + Perplexity + Instantly)
A fully automated B2B outbound prospecting pipeline built in n8n.
A fully automated B2B outbound prospecting pipeline built in n8n. Verifies raw email deliverability via NeverBounce, pulls real-time company intelligence from Perplexity AI, crafts tailored 1-2 sentence icebreakers using OpenAI GPT-4o, and enrolls verified prospects directly into Instantly cold outreach campaigns.
- Orchestrates a 13-node resilient Directed Acyclic Graph (DAG) in n8n connecting Google Sheets, NeverBounce, Perplexity, LangChain, and Instantly
- Protects domain reputation with NeverBounce SMTP verification, immediately quarantining invalid or disposable inboxes via the If5 False branch
- Pulls real-time grounded company intelligence, funding news, and product launches via Perplexity Sonar search engine API
- Synthesizes high-converting, non-flattering 1-2 sentence icebreaker hooks under strict <35-word constraints via LangChain and OpenAI GPT-4o
- Automatically enrolls verified contacts and dynamic icebreaker tokens into Instantly.ai cold email campaigns with workspace deduplication
- Reduces outbound enrichment overhead from $0.50-$1.20 per lead down to ~$0.012 per lead (>97% cost reduction)
- Includes interactive visual DAG simulator with particle flow, live Google Sheets lead database, multi-API inspector, and 8-point automated diagnostic suite
