MX Record Checker
Look up your domain's mail servers and verify they resolve.
Check the MX records for any domain to confirm it can receive email. We list every mail exchanger by priority and verify each one resolves to an IP address.

Frequently asked questions.
What are MX records?
MX (Mail Exchanger) records tell the internet which servers accept email for your domain. Without them, you can't receive mail.
Should I have more than one MX record?
Yes — multiple MX hosts provide redundancy so mail still flows if one server is down.
What does the priority number mean?
The lower the number, the higher the priority — mail servers try the lowest-numbered MX host first, then fall back to higher numbers if it's unreachable.
Can I use my domain's A record instead of MX?
No — most modern mail servers require a dedicated MX record and won't fall back to the domain's A record to deliver mail.
Why does my MX record point to another domain?
This is normal when using a third-party email provider (like Google Workspace or Outlook) — your MX record points to their mail servers instead of your own.
How often should I check my MX records?
Check after any DNS or email provider change, and periodically thereafter — a misconfigured MX record means you silently stop receiving email.
