Valid Email Checker

Valid Email Checker is an email verification and list-cleaning platform built for marketers, agencies, e-commerce teams, and developers who rely on email. It removes invalid, risky, and low-quality addresses from your lists so your campaigns reach real inboxes — cutting bounce rates, protecting your sender reputation, and improving deliverability. Every address is checked through our own 11-stage verification flow: syntax validation, MX record lookup, SMTP handshake, mailbox-existence probe, catch-all detection, role-account detection, disposable and temporary-address detection, spam-trap detection, full-mailbox detection, and disabled-account detection. Each result returns a clear status, a 0–100 risk score, and a deliverability rating, so you know exactly which contacts are safe to send to and which to hold back. What sets Valid Email Checker apart is how it handles uncertainty. If an address can't be conclusively verified and comes back "unknown," the credit is automatically refunded — no support ticket, no fine print — and recorded in your credit history. Most verifiers quietly charge you for those inconclusive results. We don't, so you only ever pay for answers you can act on. Verify a single address in under a second, or upload an entire list for bulk verification. Lists of any size — from a few hundred addresses to very large files — are processed reliably from start to finish, and any contacts that have already unsubscribed are skipped automatically, so you're never charged to re-verify them. Valid Email Checker also connects to the tools you already use. Choose from 17 native one-click integrations with leading email marketing and CRM platforms — including Mailchimp, Klaviyo, HubSpot, Brevo, MailerLite, ActiveCampaign, and SendGrid — or automate verification through Make, n8n, and Integrately. Developers can plug directly into the REST API to validate addresses in real time at signup or anywhere inside their own applications. Getting started is simple: every new account includes 150 free credits, with no credit card required. From there, choose pay-as-you-go credits that never expire, or a monthly plan for regular senders. Card and cryptocurrency payments are both supported.
