ClearBounce

ClearBounce verifies email addresses before you send, so your campaigns stop bouncing and your sender reputation stays intact. What you get: - Bulk list cleaning with clear verdicts - valid, invalid, risky, unknown - instead of vague scores, so you know exactly what to keep and what to drop. - A real-time API for signup forms that blocks fake, dead and disposable addresses the moment someone types them. - Email Finder to discover business email addresses, verified to the same standard. - Deliverability tools: inbox placement testing and blocklist monitoring for your sending domain. - Free tools with no signup required: single email checker, deliverability test, blocklist lookup. Credits never expire. Most providers void unused credits after 12 months - ours stay in your account until you use them. Pricing starts at $4 per 1,000 verifications and drops with volume. Every new account gets 100 free credits, no card required. Integrations: Zapier, Make, WordPress, HubSpot, Mailchimp, Klaviyo, GetResponse, and a documented REST API.
