Waterfall Enrichment: Get 80%+ Email Coverage

Single-provider enrichment tops out at 40-60%. Waterfall hits 80%+.

Clay’s waterfall enrichment achieves 80%+ email coverage vs. 40-60% from any single provider.

What Is Waterfall Enrichment?

  1. Primary provider: try best-in-class tool first
  2. Secondary fallback: if no match, try provider B
  3. Tertiary fallback: if still no match, try provider C

Why Single Providers Fail

No single database has complete coverage. Different providers specialize in different data sources.

How to Build in Clay

  1. Upload prospect list with name and domain
  2. Add Hunter enrichment with skip if not found
  3. Add RocketReach with only run if email empty
  4. Add Findymail with only run if email still empty

The Takeaway

Waterfall enrichment is about wiring tools into an intelligent sequence. 80%+ coverage is the difference between outbound that scales and outbound that starves.
