AI-Powered B2B Outreach: Apollo, LinkedIn, GPT-4 & SendGrid

This n8n workflow enables scalable, AI-driven cold email outreach for sales teams and founders. It starts by scraping up to 500 leads from Apollo via Apify HTTP nodes without hardcoded API keys, then stores key data like emails and LinkedIn URLs in Supabase. LinkedIn profiles are enriched with career history and recent posts using RapidAPI, followed by data validation to filter out incomplete leads.

Next, AI agents personalize content: the Product Description Agent crafts customer profiles based on your product and their pain points, while the Story Agent generates tailored replies in a specific persona and style. An HTML Modifier ensures consistent email formatting and dynamic subjects. Finally, SendGrid dispatches emails reliably, avoiding spam issues common with Gmail, and logs statuses in Supabase.

Benefits include high-touch personalization at scale, data-driven lead qualification, and time savings on manual outreach. Ideal for growth marketers targeting B2B leads, it boosts reply rates through genuine, insight-based messaging while integrating premium tools like GPT-4.1 for superior content quality.
