Clearout is an email verification and prospecting platform that combines bulk email list validation with an email finder — allowing marketing and growth teams to both clean existing lists and discover valid email addresses for new prospects. Its real-time verification API integrates directly into sign-up forms and CRM workflows to prevent invalid emails from entering the database at source.
Product Overview
Clearout's dual positioning as both a verifier and a finder distinguishes it from single-purpose validation tools: while ZeroBounce and Bouncer focus purely on validating known addresses, Clearout also includes an Email Finder that takes a name and company domain and returns the most likely valid email address — making it a useful tool for both list hygiene and outbound prospecting data enrichment. Its verification engine checks syntax, domain validity, MX records, mailbox existence, and catch-all status — returning a confidence score alongside the deliverable/risky/invalid classification. The real-time API allows teams to verify addresses as they are captured in forms, chat widgets, or CRM imports — preventing the accumulation of invalid addresses before they damage sender reputation. Clearout's bulk verification processes large lists quickly with a detailed report breaking down the results by category, enabling teams to make informed decisions about which segments of a list to send to and which to suppress.
Key Features
- Bulk Email Verification: Upload CSV lists for batch verification — syntax, domain, MX, mailbox existence, and catch-all checks with confidence scoring.
- Real-Time API: Verify addresses at point of capture — integrate into forms, CRM workflows, and data pipelines via REST API.
- Email Finder: Find valid email addresses from name and domain — prospecting data enrichment alongside list cleaning in one platform.
- Catch-All Detection: Identify and flag catch-all domains — separate genuinely deliverable addresses from risky catch-all accepts.
- Team Workspace: Shared credits and verification history for teams — manage list cleaning workflows across marketing and sales operations.
