# Email Finder ## Overview Discover email addresses associated with a domain using a hybrid approach: free methods first (web scraping, pattern guessing, WHOIS lookup), then APIs (Hunter.io, Apollo.io, etc.) when keys are available. ## When to Use - Scan a domain to find associated emails - Find contact emails for a company - Replace email hunter functionality - Find email patterns for a domain - Verify email addresses - Enrich contact data with discovered emails ## Project Context Discovery Before finding emails: 1. Check for existing email discovery tools 2. Review available API keys (Hunter.io, Apollo.io) 3. Check compliance/privacy requirements 4. Look for project-specific `[project]-email-finder` skill ## Methodology ### Free Methods (Primary) 1. **Web Scraping** - Scan `/contact`, `/about`, `/team` pages for emails 2. **WHOIS Lookup** - Query domain registration data 3. **Pattern Guessing** - Generate patterns from names found on site: - `firstname.lastname@domain.com` - `firstnamelastname@domain.com` - `firstname@domain.com` - `f.lastname@domain.com` ### API Methods (If Keys Available) | API | Env Variable | Purpose | |-----|-------------|---------| | Hunter.io | `HUNTER_API_KEY` | Domain search + verification | | Apollo.io | `APOLLO_API_KEY` | Contact discovery | | Snov.io | `SNOV_CLIENT_ID/SECRET` | Email finder | | Clearbit | `CLEARBIT_API_KEY` | Company enrichment | ## Email Result Interface ```typescript interface EmailResult { email: s
