About This Tool
What Is an MX Lookup?
An MX Lookup is a tool that retrieves the Mail Exchange (MX) records configured for a domain. MX records specify which mail servers are responsible for receiving emails on behalf of a domain and the priority in which those servers should be used. Checking MX records helps verify that your email routing is configured correctly and supports reliable email delivery.
Why Check MX Records?
Checking MX records helps ensure that incoming emails are directed to the correct mail servers. It is useful when setting up a new email service, migrating email hosting, troubleshooting email delivery issues, or confirming DNS changes. Regular MX record checks can help identify configuration problems before they affect business communication.

Whether you're configuring business email or diagnosing mail delivery issues, an MX lookup provides a quick way to review your domain's mail server settings.
Best Practices for MX Records
Keep your MX records up to date whenever you change email providers or mail servers. Verify that the listed mail servers are active, use appropriate priority values, and review your DNS configuration after making changes. Regular monitoring helps maintain reliable email delivery and reduces the risk of communication issues.
