Real SMTP handshakes
We talk to the actual mail server for every address and ask if the mailbox exists. Syntax-and-MX-only tools wave through addresses that will hard-bounce on send day.

Clean a whole list in three easy steps
No setup, no sales call, no “book a demo”. Just you and a tidy list.
-
Step 1
Upload your CSV
Drag in any spreadsheet up to 120,000 rows. We auto-detect the email column — no reformatting, no templates to download.
-
Step 2
We verify every address
Each one gets a real SMTP handshake with its mail server — plus catch-all resolution, disposable and role-based detection. Not just a syntax check.
-
Step 3
Download your clean list
Your CSV comes back with a status, reason and flags on every row. Keep the deliverables, drop the duds, segment the risky ones.
What “free” actually means here
100
verifications the moment you sign up — enough to clean a real list, not a five-row teaser.
0
cards required. We don't ask for payment details until you decide you want more verifications.
5
single checks per day on this page, forever, without even creating an account.
Friendly on the outside, serious underneath
The same verification engine that powers our developer API runs every row of your list.
Catch-all resolution
Catch-all domains usually come back as a shrug — “risky”. Our proprietary resolution engine — purpose-built algorithms and data sources — sees straight through accept-all domains and returns a real answer where other tools give up, so far more of your list gets verified.
Disposable & role detection
Throwaway inboxes, role addresses like info@ and sales@, and free providers are all flagged per row, so you can filter them out (or keep them) in one sort.
Unknowns refunded
Some servers just won't say either way. You only pay for confident results — unknowns are refunded automatically, on single checks and in bulk.
Per-row results
Status, catch-all flag, disposable flag, role flag and free-provider flag appended to every single row of your original CSV.
API when you're ready
A simple REST API with key auth lets you verify at signup so bad addresses never get onto your list in the first place. Same credits, same pricing.
Pricing that starts at free and stays fair
1 verification = 1 address checked. They never expire. You only pay for confident results — unknowns are refunded.

Questions people actually ask
Is the bulk email verifier really free?
Yes — every new account gets 100 free verifications and we never ask for a card. That's enough to clean a small list end to end. You can also run 5 single checks a day right on this page without even signing up. Need more? Packs start at $7.50 for 1,000 verifications.
How do I verify a list of emails in bulk?
Three steps: upload your CSV (any column layout — we auto-detect the email column), we verify every address with live SMTP checks, then you download your list back with a status, reason and flags added to every row. Lists up to 120,000 addresses per job.
What results do I get for each email?
Every row comes back as deliverable, undeliverable, risky or unknown, plus flags for catch-all domains, disposable addresses, role-based addresses (like info@) and free providers.
What happens to unknown results in a bulk job?
You only pay for confident results — unknowns are refunded. Whenever a server won't give a definitive answer, that verification is automatically credited back, on single checks and in bulk.
Do you keep my email list?
Your list is processed transiently for verification, and the results stay in your account only so you can download them. We never send mail to your addresses, never share or sell your list, and you can delete jobs whenever you like. The fine print is in our privacy policy.
Your list deserves a spring clean
100 free verifications are waiting. No card, no catch, no “talk to sales”.
