In their own words
Cleanlist
Cleanlist is a go-to-market platform for finding people and companies, enriching contact records, checking emails, qualifying leads, and sending lists to a CRM. Buyers can describe their target audience in plain English, then adjust the resulting people and company filters. Separate email and phone lookup processes draw on more than 25 providers each; unsuccessful lookups are not billed. Email checks cover syntax, domain, and mailbox, and identify catch-all results. AI agents can research company websites and news, respond to questions set by users, score and rank leads, and attach supporting links. Integrations support two-way sync with HubSpot, Salesforce, and Pipedrive, alongside delivery to Outreach, Salesloft, and Lemlist. A Chrome extension enriches contacts from LinkedIn, other sites, and Salesforce. Cleanlist offers web, API, and extension access. The free plan includes 30 monthly credits; paid plans start at $59/mo billed annually. New workspaces receive a 14-day Scale trial with 250 credits and three seats, without a card; public API and MCP access are excluded.
