Verify Mail Exchange routing and server priority ranks in real-time.

About MX Records Inspector

Mail Exchange (MX) records tell internet servers where to direct incoming email messages for your domain. Incorrect or missing MX records prevent your domain from receiving emails entirely.

How to Use This Tool:
  • Enter your target domain name.
  • Click "Check MX".
  • Inspect the list of mail servers and their corresponding priority numbers (lower numbers represent higher priority).
Frequently Asked Questions

Priority values determine the order in which sending servers attempt connection. A server with priority 5 will be tried before a server with priority 10.
