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 |
| 500 prospects | 40+ hours | 1-2 hours |
| 1000 prospects | 80+ hours | 2-3 hours |
Quality Checklist
Before launching any campaign:
- Email bounce rate < 2%
- At least 70% email coverage
- ICP criteria verified
- Recent signals tagged
- Duplicates removed
- Competitor customers flagged
- Do-not-contact list checked
Common Mistakes
- Single source reliance - Limits coverage
- Skipping verification - Kills deliverability
- Over-filtering - Shrinks TAM too much
- Under-filtering - Wastes outreach on bad fits
- Ignoring signals - Missing hot prospects
