Cold Email Icebreakers from Local Business Search with GPT-4 and Dumpling AI

This workflow helps digital marketers and outreach specialists automate the research and creation of cold email icebreakers for local businesses.

What it does:

Starts with a Form Trigger, where you input a search keyword (e.g., “Dentist in New York”). Uses Dumpling AI’s Google Maps API to search for local businesses matching the keyword. Extracts individual business data, including website URLs. Sends each website to Dumpling AI to extract: A website summary for personalization An email address (if available) Sends the summary and business info to GPT-4 via OpenAI to write a short, warm, and customized icebreaker message. Filters out results with missing email addresses. Logs the business name, email, website, phone number, website summary, and generated icebreaker into Google Sheets. Optionally pushes the lead and personalization to Instantly.ai for automated cold outreach.

Tools Used:

Form Trigger (n8n) Dumpling AI (Search & Extraction APIs) OpenAI GPT-4 (via LangChain Node) Google Sheets Instantly.ai (optional lead delivery)

🛠️ How to Customize the Workflow

Change the search region or business type:* Adjust the default keyword in the Form Trigger* or connect a different input source (like Google Sheets). Customize the prompt:* Modify the GPT-4 node prompt* to match your agency tone or outreach style. Add or remove data fields:* Edit the Google Sheets node* to store additional business data or remove unnecessary ones. Connect to your CRM or outreach tool:* Replace or extend the Instantly API node* with your own CRM (e.g., HubSpot, Close, Pipedrive) using HTTP Request or native integrations. Control batching size:* The Split In Batches node* is set to 2 by default. You can increase this to speed up processing or reduce it to avoid rate limits.

This automation is ideal for sales teams, digital marketing freelancers, and agencies who want to scale lead generation while keeping emails personal and relevant.
