ClearBounce is a bulk email verification and list cleaning platform designed for businesses that rely on email marketing, transactional emails, and lead generation. Built for accuracy and speed, ClearBounce helps companies reduce bounce rates, protect sender reputation, and maximize email deliverability. At the core of ClearBounce is a proprietary multi-stage verification engine that processes every email through multiple layers of validation in real time. This includes syntax validation, DNS and MX record lookup, live SMTP mailbox probing, catch-all domain detection, disposable and temporary email filtering, spam trap identification, role-based address detection, and intelligent typo suggestion. The result is a 99.5% accuracy rate with less than 2% unknown emails. ClearBounce offers several products to cover the full email deliverability lifecycle. Bulk List Verification allows users to upload CSV, XLSX, or TXT files and verify thousands of emails with detailed deliverability reports and downloadable clean lists. The Real-time REST API provides sub-50ms response times for verifying emails at the point of signup, checkout, or any automated workflow. ClearBounce Shield is a lightweight JavaScript widget that validates emails in real time on signup and contact forms, blocking invalid, disposable, and risky addresses before they enter your database. The Deliverability Kit helps businesses monitor and improve their inbox placement with tools including inbox placement testing, 24/7 blocklist monitoring for IPs and domains, and SPF/DKIM/DMARC authentication validation with instant alerts. ClearBounce integrates directly with popular email marketing platforms and CRMs including Mailchimp, HubSpot, Klaviyo, ActiveCampaign, Zapier, Make, Brevo, Constant Contact, MailerLite, GetResponse, Moosend, and AWeber. Users can import contacts, verify in bulk, and write results back automatically. Pricing is flexible with no long-term commitments. A free plan includes 100 verification credits with no credit card required. Pay-as-you-go pricing starts at $0.004 per email with volume discounts up to 1 million or more emails. Monthly subscriptions offer additional savings. All data is encrypted, GDPR compliant, and automatically deleted after 60 days.
