1. Cleanlist AI: Best for B2B teams under 300 people who want verified emails
Cleanlist AI: B2B teams under 300 people who want verified emails and phone numbers from 25+ providers in one waterfall, paying only for results
Cleanlist AI puts the weekly outbound job on an agent. Clu builds it from one sentence: it searches 1B+ profiles, runs each lookup through a waterfall of 25+ data providers for a verified work email and a phone number, adds the people to a sequence with email, LinkedIn and call steps, and posts each run to Slack. On Pro and Enterprise, contacts sync both ways with HubSpot, Salesforce and Pipedrive.
- Clu and agents that run on a schedule or a CRM trigger
- People and Company Search over 1B+ profiles at 0 credits
- Waterfall across 25+ providers with SMTP and catch-all verification
- Sequences with email, LinkedIn and call steps
- HubSpot, Salesforce and Pipedrive sync on Pro and Enterprise
- MCP server (30+ tools, from Starter) and REST API (from Pro)
Strengths
- A phone number is 10 credits from the same credit pool as the email
- A lookup that finds nothing costs nothing
- Search is free, so you pay only for the contacts you keep
- Every seat adds its credits to one shared balance: 750 on Starter, 1,500 on Pro
Limitations
- Costs more a seat than Unify: $49 on Starter, against $20 on Unify Base
- Sells no intent, job-change or website visitor signals
- No built-in dialer
