Business Email Extractor
Extract business email addresses from Google Maps at scale. Find verified contact emails for any industry and location — ready for outreach campaigns.
When to Use
- User needs business email addresses for outreach
- User asks to "find emails" for businesses in an area
- User wants to build an email list for cold outreach
- User needs contact information for a specific industry
Important: Credit System
Each extraction costs 2 credits. Free accounts get 10 credits (5 extractions).
Email extraction uses deep website crawling — always enable email: true.
Workflow
Step 1: Define Target
Ask the user:
- Industry: What businesses to target?
- Location: Where?
- Volume: How many emails needed?
- Quality preference: Only custom domains? Or include generic (info@)?
Step 2: Optimize for Email Coverage
Tips to maximize emails per credit:
- Professional services (lawyers, accountants) have 60-80% email coverage
- Restaurants/retail have lower coverage (30-50%)
- Always use
depth: 2 + email: true for maximum extraction
Step 3: Confirm
✉️ Email Extraction:
Target: {{industry}} in {{location}}
Expected emails: 15-50 (depending on industry)
Cost: 2 credits
Proceed?
