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	name@company.com, domain matches website	Use first
⭐⭐ Medium	info@company.com, custom domain	Good for outreach
⭐ Low	@gmail.com, @yahoo.com	Use with caution
❌ Remove	noreply@, no-reply@, invalid format	Skip

Step 6: Deliver Clean Email List

✅ Email Extraction Complete!

Total businesses found: {{total}}
Emails extracted: {{email_count}} ({{pct}}% coverage)

Quality breakdown:
  ⭐⭐⭐ High quality: {{high}} emails
  ⭐⭐ Medium quality: {{med}} emails
  ⭐ Low quality: {{low}} emails

Saved to: emails_{{industry}}_{{location}}.csv
