Cleanlist AI vs Shoutout

Waterfall Enrichment Engine

This is the intelligent core of Cleanlist AI, designed to maximize data coverage and accuracy through a cyclical, multi-source approach. When you upload a list, the system doesn't rely on a single provider; instead, it cascades through over 15 integrated data sources in a specific sequence, paying only for successful matches. This iterative process ensures you get the highest possible fill rates for emails and phone numbers, consistently achieving a 98% accuracy rate and transforming incomplete leads into fully enriched, actionable contacts ready for your campaigns.

Waterfall Enrichment is a sequential query system designed for maximum efficiency and coverage. When you request contact data for a lead, Cleanlist AI first checks its own proprietary cache.
