2. Supabase Sink: Persists email, linkedin_url, and ingestion timestamp.
3. LinkedIn Enrichment: Fetches career history and latest 5 posts via RapidAPI.
4. Data Validation: Conditional nodes drop incomplete or irrelevant leads.
5. Product Description Agent: Creates a customer profile based on the product and how it can help them.
6. Story Agent: Has the persona, style of speech and rules to generate reply for the customer based on the pain points and solution found by the Product Description agent.
7. HTML Modifier: Contains a fix format to keep the output format of each mail consistent and also generate a subject for the mail.
8. SendGrid Dispatch: An SMTP service which delivers emails in large quantity and also keep your mail spam free otherwise if you use gmail node your mail will go staright to spam; updates status=true/false in Supabase.

2. Configure environment variables for Apollo.io, RapidAPI, OpenAI, SendGrid, and Supabase.

✅ Requirements

• n8n 0.300.0+
• Accounts & API keys for Apollo.io, RapidAPI (LinkedIn), OpenAI, SendGrid, Supabase

🎨 How to Customize

🔐 Security Reminder: All credentials must be stored in n8n’s credential manager—never hard‑code API keys in HTTP nodes.
