Frequently Asked Questions
What is waterfall enrichment?
+
Waterfall enrichment is a data strategy that queries multiple data providers in sequence until it finds the best available information for a given record. Instead of relying on a single database (which inevitably has gaps), waterfall enrichment cascades through 15+ sources to maximize coverage and accuracy. The result: higher match rates and fewer gaps than any single provider.
How does waterfall enrichment differ from single-source enrichment?
+
Single-source enrichment queries one provider and returns whatever they have - typically 50-70% coverage. Waterfall enrichment queries multiple providers sequentially, achieving 85-95% coverage by combining the best data from each source. It also validates data across providers for higher accuracy and uses field-level optimization to pull the best data point for each field.
Which data providers does Cleanlist query?
+
Cleanlist queries 15+ premium data providers including Wiza, Findymail, Prospeo, Lusha, and more. Our proprietary algorithm selects the optimal provider order based on data type, geography, and historical accuracy. Each response is validated before inclusion in the final golden record.
How much does waterfall enrichment cost?
+
Cleanlist uses simple credit-based pricing: 1 credit for email-only enrichment (partial), 11 credits for full contact enrichment (email + phone + company data). Plans start at $0/month with 30 free credits. No hidden fees, no setup costs, and unused credits roll over for up to 3 months.
Does it integrate with my CRM?
+
Yes. Cleanlist integrates natively with Salesforce, HubSpot, Pipedrive, Outreach, Salesloft, and 10+ other platforms. You can also use the REST API, webhooks, Zapier, Make, or n8n for custom integrations. Push enriched data directly to your CRM with field-level mapping.
What accuracy rate does Cleanlist achieve?
+
We guarantee 98% data accuracy. Every email is triple-verified (syntax check, DNS/MX lookup, SMTP handshake) including catch-all detection. Phone numbers are format-validated. Company data is cross-referenced across sources for consistency.
