Building a Clean Lead List in Clay

Data Sources

While Clay has its own built-in database, consider supplementing with specialized databases depending on your niche:

• Storeleads — recommended for Ecommerce and DTC brands

Cleaning Process

Building a truly clean list requires multiple cleanup passes:

1. Company-level cleanup — validate and deduplicate company data
2. Contact-level cleanup — find and verify individual people within those companies

This multi-step approach ensures data quality across both dimensions of your lead list.
