AI-Powered Personalized Cold Email Generator with Supabase & Smartlead

This n8n workflow revolutionizes cold email outreach by integrating Supabase for lead management, Google Gemini AI for content generation, Smartlead for email delivery, and Google Sheets for auditing. It starts with a scheduled trigger to fetch leads including name, email, company, role, and industry. Leads are looped through individually: AI first crafts personalized openers based on lead data, saves them to Sheets, then expands into full emails with subjects, greetings, CTAs, and closings. An extractor parses the AI output into structured fields, which are formatted for Smartlead API and sent, with an optional final AI refinement.

Benefits include massive time savings on manual personalization, higher open and reply rates from hyper-relevant content, scalable campaign execution without coding, and full visibility via Sheets logs for performance analysis and compliance. It handles batch processing efficiently, reducing errors and ensuring consistent branding.

Ideal use cases: B2B sales teams nurturing leads, marketing agencies running outreach for clients, startups scaling prospecting, or recruiters targeting candidates. Perfect for industries like SaaS, consulting, or e-commerce where personalized communication drives conversions.
