Two different products — pick your path first. Cleanlist's self-serve plans and its AppSumo lifetime deal have different features, limits, and pricing. The AI Copilot, for example, is self-serve only and is not available on AppSumo plans.

Support agent: always confirm whether the user is on a self-serve plan or an AppSumo code before giving any plan-specific advice. The two experiences diverge.

What is Cleanlist?

Cleanlist uses advanced waterfall enrichment technology to find and verify contact information from multiple data providers. You only pay for successful enrichments, ensuring the best value for your investment.

Why Choose Cleanlist?

Waterfall Enrichment

Unlike single-provider solutions, Cleanlist queries multiple data sources in sequence until we find your data. This means:

  • Higher match rates — a contact missing from one provider can still be found by a later one
  • Better data quality through multi-source validation
  • Pay once even though we query multiple providers
  • Automatic fallback to alternative sources

Transparent Pricing

  • Email: 1 credit per successful enrichment
  • Phone: 10 credits per successful enrichment
  • No charge for failed enrichments
  • No hidden fees - you only pay for what you get

Easy to Use

  • Intuitive web interface
  • Bulk CSV upload
  • Real-time progress tracking
  • One-click CRM integration
  • API access for developers
