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" \

    "keywords": ["{{industry}} in {{location}}"],
    "lang": "en",
    "depth": 2,
    "email": true
  }'

质量中等偏上。文档清晰易懂，工作流程完整，提供了实用的行业覆盖率和质量筛选指南，合规风险提示也比较到位。主要缺点是依赖外部付费 API 服务，服务稳定性无法保障；缺少异常处理和故障恢复指导。适合对邮件提取有明确需求的用户使用，但使用前需确认 API 服务可用性并了解相关隐私合规要求。
