Look Up Mail Server Records

The MX Record Lookup tool checks a domain's DNS settings and returns the mail servers responsible for handling email delivery. It shows each server's hostname, priority, and optional TTL value, helping you verify whether a domain is set up correctly for email. This is useful for IT teams, email admins, and support staff who need a quick way to inspect mail routing.

Check Email Configuration

Use this tool to confirm whether a domain has valid MX records before sending mail or troubleshooting delivery problems. By seeing which servers are configured and how they are prioritized, you can spot misconfigurations, missing records, or unexpected routing. It saves time compared with manual DNS checks and helps reduce email issues caused by incorrect domain setup.

Review Domain Email Setup

Once the lookup is complete, the results are shown in a table with Mail Server Hostname, Priority, and TTL. This makes it easy to compare records, copy the details into reports, or share them with teammates. The structured output helps you document domain email settings and keep troubleshooting notes organized for future reference.

Support Troubleshooting Workflows

MX lookups are especially useful for support, infrastructure, and operations teams handling email delivery problems, domain onboarding, or DNS verification. Instead of checking records one by one in a DNS console, you can enter a domain and review the mail routing details in one place. That makes it easier to validate configurations and resolve email-related issues faster.
