Is that email real? Check it free.
Paste up to 10 addresses and see which ones will bounce, which are throwaway inboxes and which look fine. No account, no card, and we don't keep what you paste.
No signup. We never store the addresses you paste here.
Free means free. Here's what's in it.
And the parts that need the full check, so there are no surprises.

Whole lists
The free check takes 10 addresses a day. A CSV with thousands of rows goes through a list clean.
Seven labels.
No guessing.
Every address gets one label. If we can't be sure, the label says so.
How list cleaning results work- Valid
The mail server confirmed the mailbox exists. Safe to send.
- No mailbox
The mail server told us this mailbox doesn't exist. It will bounce.
- Will bounce
The domain has no mail server, or it's a typo of a big provider like gmial.com.
- Disposable
A throwaway inbox. Whoever used it won't read your mail.
- Bad format
Not a valid email address, so nothing can be delivered.
- Risky
A shared inbox like info@, or a server that gave a mixed answer. It might deliver, it might not.
- Needs full check
The address looks fine, but confirming the mailbox needs the full check. We'd rather say so than guess.

About the free checker
01Is the email checker really free?+
Yes. You can check up to 10 addresses a day without an account or a card. If you want to clean a whole list, every account also gets 100 free credits.
02Do you save the addresses I check?+
No. The addresses you paste here are checked and then discarded. We only keep a count of how many checks your connection has used today, so we can apply the daily limit.
03Why does my address say "Needs full check"?+
The free check runs a live mailbox test for Gmail, iCloud, Proton, Hey and Fastmail addresses. For business and custom domains, confirming the mailbox needs the full check, so we label it honestly instead of guessing.
04Can you check Yahoo, Outlook or Hotmail addresses?+
Not at the mailbox level. Yahoo, Outlook, Hotmail and AOL don't let anyone confirm whether a single mailbox exists. We still catch typos, bad formats and disposable addresses on those domains.
05How is this different from cleaning a list?+
The free check is for a handful of addresses. A list clean takes a CSV of any size, checks every address, sorts them into five groups with a reason for each, grades the list from A to F and gives you a clean file to import back into your email platform.
06How many addresses can I check for free?+
Up to 10 a day from the same connection. The limit resets every 24 hours.
Got a whole list to check?
Upload a CSV from MailPoet, Mailchimp, Klaviyo or anywhere else. Every account starts with 100 free credits, and paid credits never expire.
