n8n Spintax Workflow: Generate Unique Cold Email Copy per Lead

Generate unique cold email copy for every lead—deterministically

This n8n workflow renders a unique, personalized cold email subject and body per lead using the n8n-nodes-spintax Spintax node. Each lead gets copy that’s different (and reproducible) based on the lead’s fields and a seed—then the final text is ready to map into your sending tool.

What this workflow does

• Runs on demand via a Manual Trigger (execute manually when you’re ready to generate a batch).
• Loads a list of leads (or products) using a Code step you’ll replace with your real source (e.g., Google Sheets, Airtable, or a CRM). Required fields include things like first_name, company, product, price, in_stock, and has_discount.
• Renders a unique subject per item using Spintax, pulling variables from each lead and using a seed based on the company to keep output consistent.
• Renders a personalized email body with Spintax variables plus conditionals (e.g., discounts when has_discount is true) and pluralization (e.g., stock counts based on in_stock).
• Outputs rendered text for each item so you can map the subject and body into your email platform, Gmail, or SMTP step.

Use cases

• Generate individualized cold email batches for a SaaS outreach campaign.
• Produce unique product-specific email variations for different catalogs and pricing.
• Maintain consistent variations across reruns using Spintax seeds per company.
