Free email checker
Check one address at a time, free. This is the same fast check the API runs.
What it checks
- The address is valid email syntax.
- The domain exists, isn't reserved, and has mail servers that accept email.
- Disposable (temporary) email domains, role addresses and no-reply addresses.
- Likely typos of common providers, with a suggested fix.
It doesn't connect to the mail server, so it can't tell whether the mailbox itself exists. Each reason is explained in the documentation.
Limits and privacy
Up to 10 checks an hour and 30 a day from one network, with a captcha by Cloudflare Turnstile. We don't store or log the addresses you check here.
