1. Cleanlist AI: Best for teams that want verified work emails
Cleanlist AI: Teams that want verified work emails and phone numbers from a multi-provider waterfall, returned in an app, a CRM sync or one API call, without building pipelines around raw JSON.
Cleanlist AI runs waterfall enrichment across 25+ data providers in sequence and stops at the first verified hit. A verified work email costs 1 credit, a phone number 10, and a miss costs nothing. Results land in the app, sync two-way to HubSpot and Salesforce on Pro and Enterprise, or come back through the REST API (Pro and up) or the MCP server (Starter and up). Sequences sends email from your own inbox, with call tasks, on every paid plan. Cleanlist AI does not license bulk files or sell a dataset.
