Check a domain’s MX records

Find the mail servers responsible for receiving email, compare their priorities, and catch missing DNS records before they affect delivery.

How to read MX records

An MX lookup shows where email for this domain should be delivered.

Hostname
The receiving mail server that handles messages for the domain.
Priority
The delivery preference. Lower numbers are tried first.
Redundancy
Multiple records provide alternate destinations when a preferred server is unavailable.
