How does MX Lookup work?
Just enter a domain name (e.g. example.com) and click “Check”. Our tool instantly scans the domain’s DNS records and returns all MX entries, including their associated mail servers, priority values, IP addresses, and TTL (time-to-live). Results are displayed in a clear, easy-to-read format, so you can quickly spot issues or confirm your email setup is working as intended.
What are MX records?
MX (Mail Exchange) records direct emails to your domain’s mail servers. They specify which servers are responsible for receiving emails and their priority order. Correct MX records are critical for making sure emails reach their destination. If they’re misconfigured, emails may bounce or fail to deliver entirely.

- What does the priority value mean for MX records?
The priority value determines the order in which mail servers are used. Lower numbers (e.g., 10) have higher priority and are tried first. If the primary server fails, emails are routed to the next server in line (e.g., 20).
- How can you find MX records for any domain?
Use our free MX Lookup tool: enter the domain name, and we’ll retrieve all MX records instantly. You’ll get instant results without the need to sign up or provide any personal information.
- How do you interpret multiple MX records?
Multiple MX records provide redundancy. If the highest-priority server is unavailable, emails will route to the next server in line. Make sure that all listed servers are properly configured to avoid delivery failures.
