# 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
