Cold Outreach Automation: Dumpling AI Scrape + Vapi Calls

Cold Outreach Automation that Scrapes Local Leads and Places AI Calls

This n8n template automatically generates cold outreach lists from Google Maps (via Dumpling AI) and then uses a Vapi AI assistant to place outbound calls to local businesses—no manual dialing or lead research required. Each successful call is logged in Google Sheets for follow-up and tracking.

What this workflow does

• Pulls outreach queries from a Google Sheets column (e.g., “plumbers in Austin”).
• Sends each query to Dumpling AI’s Google Maps scraping endpoint to retrieve business listing data.
• Splits** the returned results into individual leads.
• Extracts key fields such as business name, website, and phone number.
• Filters to keep only leads with valid phone numbers.
• Formats phone numbers for Vapi dialing (adds +1).
• Uses Vapi to call each business with an AI-powered outbound assistant.
• Logs successful calls into a Google Sheet so your sales team can track outcomes.

Use cases

• Agencies generating local lead lists for multiple client niches and running consistent AI cold call outreach.
• Local service providers (plumbers, restaurants, contractors) who need faster lead generation from nearby businesses.
• Sales teams looking to reduce time spent researching contacts and initiating first calls.
