Email List Validation

Valid Email Checker is a fast, accurate email verification and list-cleaning platform for marketers, agencies, e-commerce and developers who want to cut bounce rates and protect sender reputation. Every address runs through our own 11-stage verification flow — syntax, MX, SMTP handshake, mailbox probe, catch-all, role-account, disposable, spam-trap, full-mailbox and disabled-account checks — returning a clear status plus a 0–100 risk score and deliverability rating. Our standout promise: if a check comes back Unknown, we automatically refund the credit — no ticket, no fine print. Most verifiers charge you for those; we don't, and every refund shows in your credit history. Verify one address in under a second, or bulk-check entire lists with a resumable engine that never times out. Connect 17 native ESP/CRM integrations (Mailchimp, Klaviyo, HubSpot, Brevo and more), plus Make, n8n and Integrately, or our REST API. New accounts start with 150 free credits.
