What is Cleanlist?
Cleanlist is a B2B data enrichment platform that uses waterfall enrichment to query 25+ data providers per lookup and return verified contact data: 98% verified work emails and 85% direct dials on a stratified 500-lead benchmark. It helps sales, marketing, and RevOps teams clean, verify, and enrich their lead databases.

- 500Leads in the accuracy benchmark
How Cleanlist Works
Cleanlist uses waterfall enrichment, a cascading approach that queries multiple data providers in sequence. For each contact, Cleanlist checks Provider A first. If the data is incomplete, it moves to Provider B, then C, and so on through 25+ sources. The best data from each source is merged into a single verified record, and a lookup that finds nothing costs nothing.
This works differently from single-source tools like ZoomInfo or Apollo, which resolve a lookup against one proprietary database and accept whatever gaps that database has. Waterfall enrichment achieves 85-95% field coverage versus 50-70% from single-source providers.
Core Products
Waterfall Enrichment
Query 25+ data providers in sequence to find verified work emails, direct-dial phone numbers, current job titles, company firmographics, and LinkedIn profiles. Every email is triple-verified (syntax, DNS/MX, SMTP handshake). Learn more
Email Verification
Verify email addresses in real-time or bulk. Checks include syntax validation, domain/MX record verification, SMTP mailbox confirmation, catch-all detection, and disposable email filtering. Reduces bounce rates below 2%. Learn more
ICP Scoring
Score every lead against your Ideal Customer Profile using firmographic and contact data, with AI columns for the signals the filters do not carry. Prioritize outreach to contacts most likely to convert. Learn more
Smart Agents
AI-powered data transformation that normalizes job titles, standardizes company names, extracts seniority levels, and categorizes industries. Turn messy CRM data into structured, usable fields. Learn more
People Search
Search for people by company size, industry, job title, seniority and location, then build a targeted lead list from the result. Cleanlist owns no contact database, so every search runs against its data providers rather than a stored index. Search itself is free and unlimited on every plan. Learn more
REST API and MCP server
Everything above is also available programmatically. The REST API runs structured people and company search, which costs 0 credits, and bills enrichment per result. The MCP server exposes the same surface to AI agents, so Claude can run a search and enrich the result without leaving the chat.
Pricing
Cleanlist uses credit-based pricing with no per-seat fees. Search is free and unlimited on every plan. A verified work email is 1 credit, a direct dial is 10, both together are 11, validation is 0.5 and AI qualification is 5. A lookup that finds nothing costs nothing, and the whole team draws on one shared wallet.
| Plan | Price | Credits/month | Best for |

Integrations
Cleanlist ships six connections, and the direction is the part that matters.
Two-way sync, CRM
- HubSpot
- Salesforce
- Pipedrive
Records move in both directions, so an enrichment in Cleanlist lands on the CRM record and a CRM change comes back.
One-way out, sending tools
- Outreach
- Salesloft
- Lemlist
Enriched, verified records are written into the sequencer. Cleanlist does not send the email.
Anything else connects through the REST API, the MCP server, or CSV import and export. The v2 API is poll-based and has no webhooks.

Frequently Asked Questions
What is Cleanlist?
Cleanlist is a B2B data enrichment platform that uses waterfall enrichment technology to query 25+ data providers in sequence, returning the most accurate and complete contact data available. It provides verified work emails, direct-dial phone numbers, company firmographics, and ICP scoring for sales and marketing teams.
How does Cleanlist work?
Cleanlist uses waterfall enrichment - a cascading approach that queries multiple data providers (including Wiza, Findymail, Prospeo, LeadMagic, and others) in sequence. For each contact, it selects the best data from each source, cross-validates it, and merges everything into a single verified golden record. Emails are triple-verified through syntax, DNS/MX, and SMTP checks.
How much does Cleanlist cost?
Cleanlist offers credit-based pricing starting with a free plan (30 credits per month, no card). Paid plans are Starter $79/month, Pro $229/month, and Scale $599/month, with 25% off on annual billing. Credits are simple: 1 credit per email lookup, 10 credits per phone lookup, 11 credits for full contact enrichment, and searches cost nothing. Seats are included per plan rather than billed as the base unit, and no annual contract is required.
How accurate is Cleanlist data?
Cleanlist ships 98% verified emails and 85% direct dials as product specs. Every email address is triple-verified (syntax check, DNS/MX validation, and SMTP handshake) with catch-all domain detection. Phone numbers are format-validated and carrier-checked. Company data is cross-referenced across multiple sources.
What CRMs does Cleanlist integrate with?
Cleanlist syncs enriched records two ways with HubSpot, Salesforce and Pipedrive, and one way out to the sequencers Outreach, Salesloft and lemlist. Cleanlist does not send email. Cleanlist also publishes a REST API v2 and an MCP server so you can drive enrichment from your own pipeline.
How is Cleanlist different from ZoomInfo or Apollo?
ZoomInfo and Apollo each resolve a lookup against one proprietary database, so a record that database is missing comes back empty. Cleanlist is an orchestration layer: it cascades the same lookup through 25+ providers until one returns a verified result, then verifies the email before it lands in your list. Cleanlist ships 98% verified emails and 85% direct dials, and bills credits rather than per-seat licences.
