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?

Step 4: Extract

curl -X POST "https://gmapsscraper.io/api/v1/jobs" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $GMAPS_SCRAPER_API_KEY" \
  -d '{
    "name": "Emails: {{industry}} in {{location}}",
    "keywords": ["{{industry}} in {{location}}"],
    "lang": "en",
    "depth": 2,
    "email": true
  }'

Step 5: Download & Filter Emails

curl -s "https://gmapsscraper.io/api/v1/jobs/{{job_id}}/download" \
  -H "Authorization: Bearer $GMAPS_SCRAPER_API_KEY" \
  --output raw_results.csv

Quality filtering:

Quality	Pattern	Action
⭐⭐⭐ High	[e-mail], domain matches website	Use first
⭐⭐ Medium	[e-mail], custom domain	Good for outreach
⭐ Low	@gmail.com, @yahoo.com	Use with caution
❌ Remove	noreply@, no-reply@, invalid format	Skip
