Never Send to a Bad Email Again

Every bounced email damages your sender reputation. Cleanlist verifies emails with triple-layer validation before you hit send.

Start free trialHow It Works
The short answerEmail verification

Upload a CSV, sync a CRM segment or call the API, and every address is checked for syntax, for a live MX record, and then at the mailbox itself through an SMTP handshake. Each row comes back valid, risky or invalid, with catch-all domains, disposable addresses and known spam traps flagged separately so you can segment the send instead of guessing at it. Validating a record you already hold costs 0.5 credits, and finding a new verified work email costs 1.

Bad Emails Cost More Than You Think

Every invalid email in your outreach damages deliverability for your entire domain.

  • High bounce rates killing domain reputation

    Triple verification catches invalids before send

  • Emails landing in spam instead of inbox

    Clean lists mean higher sender scores

  • Wasting credits on undeliverable addresses

    Only pay to reach real inboxes

  • Can't tell if catch-all emails are real

    Catch-all detection flags risky addresses

  • Disposable and role-based emails polluting lists

    Auto-detection removes junk signups

  • No idea which emails decayed since last send

    Re-verify before every campaign

    Catch known spam trap addresses before they damage your sender score.

  • Disposable Email Filtering

    Auto-remove temporary email addresses from signup forms and lead lists.

  • Deliverability Scoring

  • Bulk & Real-Time

    Verify thousands in batch, or single emails via API.
