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.

Findthat
Find the email address of professionals in millions of companies worldwide. Use our Chrome Extension to find and prospects emails from social networks like Linkedin, Facebook, Twitter. Find various email addresses from a list of names and companies or domains. Clean any sized list to eliminate hard bounces and improve your email marketing campaigns performance. Some mail servers are set to accept all emails sent to them whether the address exists or not (also called ‘Catch-All’). While other services rely on server responses to determine whether an email is valid, Findthat uses a diverse set of data sources and requires that at least two sources will flag an email as valid before we call it. Mailbox providers will determine your sender reputation based on the amount of hard-bounces (mailing to unknown users) you send.

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.

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.
