Valid Email Checker
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.

Sealch
Sealch is an email verification service that runs the same live SMTP and catch-all check as ZeroBounce and NeverBounce — at a flat $0.35 per 1,000, roughly 10× cheaper. Upload a CSV or call the bulk API, and every address is checked in real time against the recipient's mail server (no email is ever sent). Results come back cleanly segmented into deliverable, risky, and invalid, with catch-all domains flagged honestly as "risky" instead of a false "valid." You're never charged for unknowns, and credits never expire. Built for outbound and email marketing teams who need a clean list before they send — without paying enterprise prices.
