Cleanlist AI is an all-in-one contact discovery, verification, and data cleansing platform designed to eliminate the friction of modern prospecting. Instead of forcing you to rely on a single, outdated database provider, Cleanlist AI routes your lookups through a waterfall enrichment model that queries more than 15 data providers sequentially until it secures verified contact details. It cleans names, normalizes phone numbers to international standards, verifies email deliverables (including catch-all detection), and integrates seamlessly with major CRM systems.
Waterfall Enrichment (15+ Sources): Queries multiple data providers in sequence until a verified email and direct phone number are found. You only pay for successful matches.
1-Click LinkedIn & Sales Navigator Enrichment: Pulls verified emails and direct dials straight from LinkedIn or Sales Navigator via a dedicated Chrome extension.
Triple Email Verification: Performs automated checks for syntax, real domains, live mailboxes, and catch-all behaviors, returning transparent status flags (deliverable, risky, or bad).
Bulk CSV & CRM List Enrichment: Upload raw spreadsheets or pull records straight from HubSpot to standardize and enrich entries instantly.
AI Agents & Smart Columns: Run automated company/contact research, ICP-fit scoring, and custom prompt-driven enrichment workflows.
The platform is designed to minimize friction. Its workflow functions across four primary steps:
Input Data: Drop in a CSV file, paste a list of URLs from LinkedIn Sales Navigator, or look up profiles via the browser extension.
Automated Waterfall Routing: Cleanlist sweeps across 15+ data networks in real time, validating syntax and testing active mailboxes.
Data Cleaning & Scoring: First names are normalized, phone numbers are formatted into E.164 structures, and AI smart columns evaluate ICP qualification.
Sync & Export: Push verified profiles directly into your CRM or export a clean CSV file ready for outreach.
Cleanlist AI adapts to diverse industries and operational models:
B2B Lead Generation & Sales: Finds accurate direct dials and business emails to bypass gatekeepers.
Cleaning Companies & Property Managers: Cleans client lists, verifies vendor contact info, and maintains pristine communication logs.
Airbnb & Vacation Rentals: Standardizes guest data and tracks communication parameters efficiently.
Virtual Assistants & Operations Managers: Replaces manual web research and list scrubbing with automated workflows.
Drastically Lower Bounce Rates: Protects sender reputations by catching invalid or disposable mailboxes early.
Time Savings: Replaces hours of manual copy-pasting across multiple directories with instant 1-click lookups.
Predictable Budgeting: Pay-per-credit transparency ensures you never run into surprise subscription billings.
