Contracted business data providers
These are the providers Cleanlist AI holds a direct contract with. A lookup tries them in cost order and stops at the first deliverable result. That sequence is the waterfall.
| Provider | Data supplied |
|---|---|
| Anymailfinder | Work email lookup |
| Crustdata | Person and company records, firmographics |
| Datagma | Work email, phone number |
| Emailable | Email verification: syntax, DNS and mailbox checks |
| Findymail | Work email, profile URL resolution |
| Hunter | Work email, domain search |
| Icypeas | Work email lookup |
| LeadMagic | Work email, office and mobile phone numbers |
| Prospeo | Work email, phone number |
| Wiza | Person records, work email, phone number |
On the “25+ providers” figure used elsewhere on this site. Both numbers are true and they count different things. Cleanlist AI holds direct contracts with the ten above. Several of those providers are themselves aggregators that resolve a lookup across their own upstream sources, so a single Cleanlist AI request can reach more than 25 distinct data sources in total. The ten are who we contract with and who we hold to the representations below. The 25+ is the reach of the waterfall.
Processing regions are not listed per row. Where a transfer leaves the European Economic Area or the United Kingdom it is covered by section 7 of the DPA, and the current region for a named vendor is available on request.
Cleanlist AI requires each provider to represent that it holds the rights and lawful bases needed to supply the data, that it gives any legally required notice, that it supports individual rights, and that it honours applicable suppression requirements. Cleanlist AI does not operate a web crawler and does not build its own contact database by copying web pages.
Coverage and accuracy
Coverage, on this page, means the share of lookups for which the waterfall returns a verified value. Cleanlist AI does not own a database, so there is no database size to publish. Each lookup runs when you ask for it, walks the 25+ data sources the providers above reach, and stops at the first deliverable result (verified or likely valid).
What is covered, by field. A work email, checked at the mailbox before it is returned, for 1 credit. A phone number for 10 credits, or both on one row for 11. Validation of an address you already hold for 0.5 credit. Person and company records, including firmographics, from the providers in the table above. Search is free and unlimited on every plan, and a lookup that returns nothing costs nothing.
What is covered, by region. Coverage follows the providers above and varies by country, industry, company size and seniority. Cleanlist AI does not publish a coverage figure for any single region. To see your own rate, run a sample of your list.
Accuracy. 98% verified work emails and 85% phone numbers on the Cleanlist AI 500-Lead Enrichment Benchmark, which is our own test run on a 500-lead sample. It is not a third-party test, and it is not a test of any other vendor. The protocol is published with the Cleanlist AI 500-Lead Enrichment Benchmark.
What is not covered. Cleanlist AI supplies no intent data, no headcount-growth filters and no technographic database or tech-stack filters, and it holds no database of its own to query or to size. Its agents watch two signals instead: job changes among the CRM contacts they watch, each profile rechecked monthly or every two weeks, and companies that start using a tool you name.

Changes and notice
Cleanlist AI reconciles this page against the providers and vendors in production every quarter, and whenever one is added or removed. Under section 6 of the DPA, customers receive notice before a new subprocessor begins processing Customer Data, and may object on reasonable data protection grounds.
To be notified of changes, or to ask a question about a specific provider, write to support@cleanlist.ai.
