MX Record Lookup

No email address required. Only public DNS records are queried. Reports can be printed or saved as PDF for free.
What this checks
Published public DNS configuration and common problems. A healthy DNS configuration is not a guarantee of message delivery or inbox placement.

How to use this free MX checker
MX records tell other mail servers where to deliver email for your domain. Enter the domain or URL above and review the returned records and status details. The results reflect the information available when the check runs.
Understanding your MX results
Lower MX preference numbers are attempted first. Multiple MX records can provide routing alternatives depending on provider configuration.
If no MX record is published, delivery behavior can vary; confirm your mail provider’s required DNS settings.
