AI-Powered Cold Email Automation with Gmail & OpenAI

Transform your cold outreach from generic templates to personalized, high-converting emails that sound authentically human. This AI-powered n8n workflow automatically converts LinkedIn URLs into custom-written Gmail drafts, combining PeakAI's email enrichment with OpenAI's intelligent copywriting to create targeted outreach at scale.

What This Workflow Does

Starting with a simple Google Sheet of LinkedIn URLs, this automation orchestrates a complete cold email pipeline. PeakAI enriches each LinkedIn profile to find verified work emails and phone numbers, while OpenAI generates personalized email content that references the prospect's specific role, company, and pain points. Each completed email is saved as a Gmail draft, ready for your review and one-click sending.

The workflow reads pending leads from your Google Sheet, processes them through intelligent enrichment and AI copywriting, then delivers polished drafts directly to your Gmail interface. No more copy-paste templating or manual research—just conversational, personalized emails that read like you wrote them individually.

Use Cases

• Outbound SDRs replacing templated email blasts with AI-personalized outreach
• Founders and entrepreneurs running targeted email campaigns instead of mass broadcasts
• Sales teams testing AI-powered personalization before investing in enterprise sequencing tools
• Growth marketers validating outreach strategies with quality-over-quantity approaches
