Free Email Validator

Check if an email address is valid. Verifies syntax, domain DNS records, and disposable email providers.

Why Validate Email Addresses?

Sending emails to invalid addresses hurts your sender reputation. ISPs and email providers track bounce rates, and high bounce rates can land your domain on blocklists.

Validating emails before sending helps maintain a clean list, improves deliverability, and protects your domain reputation.

Syntax Check

The first line of defense. Our validator checks that the email follows the proper format: local-part@domain.tld. Simple typos like missing @ or dots are caught instantly.

Domain & MX Records

We check if the domain exists and has mail exchange (MX) records configured. A domain without MX records cannot receive email, making the address invalid.

Disposable Detection

Temporary and disposable email providers are flagged automatically. These addresses are often used for spam and can pollute your user database.

Role Account Detection

Role-based emails like admin@, info@, or support@ are flagged. These addresses often belong to departments rather than individuals and may have lower engagement.

Clean, validated email lists lead to better open rates, higher engagement, and stronger sender reputation. Start validating your emails now.

Disposable emails are temporary addresses from providers like Mailinator, Guerrilla Mail, or TempMail. They self-destruct after a short time and are commonly used to bypass signup verification.
We verify that the domain can receive mail by checking DNS MX records. However, actually probing whether a specific mailbox exists would require sending a test email (which we do not do).

No account is required. Use the tool instantly without signing up, logging in, or providing any personal information.
Syntax check is 100% accurate. MX record validation checks live DNS records. Disposable and role-account detection uses an up-to-date provider database. Actual inbox existence cannot be confirmed without sending an email.
