Email verification built for deliverability — cleaner lists, fewer hard bounces, calmer campaign reviews.
3 free checks a day. No signup, no card.
Paste any address. We'll tell you whether it's safe to send, risky for deliverability, or outright broken — and why.

Every address on your list lands in one of three places. No mystical confidence score, no vague “probably fine.” Just a verdict you can act on.
Active mailboxes on working domains. These are the addresses worth keeping in your campaign.
Valid-looking addresses that tend to hurt deliverability when you send in bulk.
Addresses that will bounce. Sending to them erodes your sender reputation one email at a time.
No mystical score, no vague “probably fine.” Each layer has a specific job, and every result comes with a reason.
Catches broken formats and silently fixes common provider typos like gmial.com → gmail.com before they ever reach your send queue.
No more bounces that were doomed the moment someone mistyped a domain.
Confirms the address actually belongs to a domain that can receive email. Dead domains and made-up TLDs are out.
Stops you sending to addresses whose letterbox has been bricked up for years.
Flags throwaway inboxes, role addresses (info@, sales@, noreply@), and providers with a reputation for deliverability trouble.
Keeps your list honest — drops the ones that were never planning to engage.
Politely asks the receiving mailbox whether it exists — without actually sending anything. Handles catch-all domains and grey-listed servers cleanly.
Asks the server a careful question, so your campaign doesn't ask it 40,000 more.
On request, adds engagement signals and known-breach indicators to high-value lists so you can tier outreach by confidence.
A little extra context when the cost of getting it wrong is high.
Pay for verified addresses. No long-term contracts, no mysterious line items, no meeting required.
