List Building Pro Tips

Core Principles

1. Mix Sources

Don't rely on just one data provider
Each source has different strengths/coverage
Combine for maximum coverage

2. Scraping = Step 1

Raw scraped data is just the beginning
Still need Clay enrichment for:
- Email verification
- Phone numbers
- Company data
- Custom signals

3. Templates Are Modular

Start with proven templates
Adjust for specific campaign goals
Don't rebuild from scratch

4. Don't Reinvent the Wheel

Use existing Clay templates
Modify rather than create
Learn from what works

Data Quality Hierarchy

1. Verified email (bounced < 2%)
2. Direct phone number
3. Recent activity signal
4. ICP fit confirmed
5. Company enrichment complete

Efficiency Benchmarks

Task	Manual Time	With Clay
100 prospects	8-10 hours	30 min
