Check format, MX records, A record, disposable status, and role-address detection. Instant, free, no signup.

What does this tool check?

Format

Validates the email follows the correct syntax (local@domain.tld).

MX Records

Confirms the domain has mail exchange DNS records and can actually receive email.

A Record

Checks that the domain resolves to at least one IP address.

Disposable Detection

Flags known throwaway email providers from a 500+ domain blocklist.

Role Address

Identifies generic role-based prefixes like admin@, info@, noreply@.

Health Score

A 0–5 rating based on all checks combined.

Does this tool send a test email?

No. Validation is done purely via DNS lookups. No email is sent and no data is stored.

Can I verify if a specific mailbox exists?

No tool can confirm a mailbox without sending mail. MX records confirm the domain can receive email, but not a specific address.

Why is a valid-looking email flagged?

The domain may be on the disposable list, have no MX records, or use a role-based prefix. All checks are explained in the result.
