About MX Lookup Tool
Quickly look up the mail exchange (MX) records for any domain name. Simply enter a domain and our tool will instantly query the DNS records and display the results in a clear, easy-to-read table.
For each mail server found, the tool shows:
- Priority – the order in which mail servers are tried (lower number = higher priority)
- Mail Server – the hostname of the mail server responsible for receiving email for that domain
- IP Address – the resolved IP address of each mail server
Use this tool to verify email routing, troubleshoot mail delivery issues, check which email provider a domain is using (Microsoft 365, Google Workspace, etc.), or simply confirm that MX records are configured correctly.
