What Is Waterfall Enrichment?

Waterfall enrichment is the gold standard methodology for B2B data enrichment. Instead of relying on a single data provider (which typically achieves 40-60% match rates), waterfall enrichment checks multiple providers in sequence, dramatically increasing overall match rates to 80-95%.

The process works like a waterfall: for each lead record, Provider A is queried first. If Provider A returns a valid result, that data is used. If Provider A has no match, Provider B is queried, then Provider C, and so on until a match is found or all providers are exhausted.

Waterfall enrichment is particularly effective for email enrichment, where different providers have strengths in different industries, company sizes, and geographies. By combining providers like Hunter.io, BounceBan, and Mailveri, platforms like Enrichabl can achieve significantly higher email match rates than any single provider alone.

The key advantage of waterfall enrichment is cost optimization. By ordering providers from cheapest to most expensive, teams can minimize per-record costs while still achieving high match rates. The BYOK (bring your own key) model used by Enrichabl makes this especially cost-effective, as customers pay each provider directly at their lowest available rate.
