Best Practices

Lead Generation Tips

Be Specific with Objectives: Use detailed objectives like “Find CTOs at Series B SaaS companies” rather than just “find executives”
Use Multiple Filters: Combine domain, topic, and keyword filters for more targeted results
Start Small: Begin with smaller limits (10-50) to test your criteria before generating larger lists
Iterate on Criteria: Refine your search criteria based on the quality of initial results

List Management

Organize by Campaign: Create separate lists for different campaigns or time periods
Use Descriptive Names: Include timeframe, target persona, and purpose in list names
Regular Updates: Update lists regularly to maintain data freshness
Backup Important Lists: Export critical lists before making major updates
