What is Email Validator?

Paste multiple emails (one per line) to validate them in bulk. The tool separates valid and invalid emails and can detect duplicates.
FAQ
- Does this verify if the email actually exists?
- No — this tool only validates the format/syntax of email addresses. It does not check if the mailbox exists or if the domain has valid MX records.
- What makes an email address invalid?
- Common issues include missing @ symbol, invalid characters, missing domain, consecutive dots, or spaces in the address.
