MX Lookup

MX Lookup is an essential tool that helps you find the Mail Exchange (MX) records associated with any domain name. These records determine which mail servers are responsible for receiving emails on behalf of that domain. If your emails are not being delivered, checking MX records is often the first and most important step.

Why Use the MX Lookup Tool

 MX records control how email flows across the internet. When they are misconfigured or missing, emails may bounce, land in spam, or fail to send entirely. This tool helps you quickly verify whether a domain has valid MX records and which email services it uses.

What This Tool Displays

 When you enter a domain name, the tool scans its DNS settings and shows:
 • The list of MX servers
 • Mail server priorities
 • Hostnames of each mail handler
 • The order in which servers receive emails
 • Any missing or invalid MX configurations

This information is useful for diagnosing issues with email delivery or migrating email services.

Common Use Cases
• Troubleshooting email delivery failures
• Verifying DNS settings after moving to a new email provider
• Checking whether a domain is using Gmail, Outlook, Zoho Mail, or a custom server
• Ensuring MX records are correctly prioritized
• Detecting configuration mistakes after domain changes or DNS edits

How to Use the Tool

1. Enter the domain name you want to check.
2. Click on the Lookup button.
3. The tool will instantly retrieve and display all MX records for that domain.

Frequently Asked Questions (FAQ)

1. What are MX records?
    MX records are DNS entries that specify which mail servers are allowed to accept email for a domain.
2. Why is the MX priority important?
    Mail servers follow the priority order. A lower value means higher priority. If the primary server is unavailable, email is routed to the next available server.
3. My domain has no MX records. Can it still receive email?
    If no MX records exist, most providers fall back to the A record. However, this is not recommended and may cause delivery issues.
4. Can I use this tool to check if my email provider is set up correctly?
    Yes. By looking at the displayed servers, you can confirm whether your domain uses Gmail, Microsoft 365, Zoho Mail, cPanel mail, or other providers.
5. How often should I check MX records?
    Check them whenever you update DNS settings, migrate email providers, or notice unusual email behavior.
