A free email verifier that checks an address's form, domain and mail servers, and flags throwaways, role addresses and typos.
5.0(1 rating)Type an email address. See whether it can take email, and whether it's a throwaway, a role address or a typo. Nothing is sent to it.
The address
Everything runs in your browser: nothing is uploaded, and no email is sent. A free check can't ask a mail server whether a mailbox exists; paid verifiers do that.
This free email verifier checks any email address without sending it anything: its form, whether its domain exists and takes email, and whether it's a throwaway, a role address, a free mailbox or a typo.
It runs in your browser, and it's plain about the one thing a free check can't know.
What is an email verifier?
An email verifier checks whether an email address can receive email before you send to it, so fewer of your emails bounce.
What the verifier checks
| Check | What it means |
|---|---|
| Form | The address follows the email standard (RFC 5321 and 5322) |
| Domain | The part after the @ exists |
| Mail servers | The domain has MX records, so it takes email; a null MX (0 .) says it takes none |
| Throwaway | The domain is one of 8,985 disposable ones, from an open list |
| Role | The address is a job, like info@ or support@ (RFC 2142), not a person |
| Free mailbox | Gmail, Yahoo, Outlook and the like, or a work address |
| Typo | gmial.com probably meant gmail.com |
Each address comes back valid, risky or invalid. Risky means look before you send, not delete.
What no free check can tell
Whether the mailbox itself exists. Only the receiving server knows, and asking it means an SMTP conversation from a server with a sending reputation to protect. That's what paid verifiers charge for.
Here's what each gives you free, read on its own pricing page on September 27, 2026:
| Service | Free checks |
|---|---|
 Verifalia | 25 a day |
 ZeroBounce | 100 a month, refilled |
 Hunter | 50 credits a month, shared with its email finder |
 Emailable | 250 once |
 Kickbox | 100 once |
 Bouncer | 100 once |
 Clearout | 100 once |
 DeBounce | 100 once |
 MillionVerifier | 100 once |
 MailerCheck | 10 once |
 NeverBounce | Free test credits, no number on the page |
Used daily, Verifalia's 25 a day adds up to the most. For a one-off list, Emailable's 250 goes furthest.
Final thoughts on verifying email addresses
Check addresses where they come in, on your signup forms, and again before a big send.
Clean a whole list with the email list cleaner, and check your own domain's setup with the email deliverability checker.

Questions about verifying email addresses? Here's what to know.
