Waterfall Enrichment
Definition
A data enrichment strategy that queries multiple data providers in sequence (a "waterfall") to maximise the coverage and accuracy of contact information. If the first provider cannot find an email, the system tries the second, third, and so on.
Why It Matters
No single data provider has complete coverage. Waterfall enrichment typically achieves 85-95% email coverage compared to 50-70% from a single source, dramatically increasing the reach of your outbound campaigns.
