About MX Lookup
MX Lookup finds the mail servers configured to receive email for a domain, listed in the priority order a sending server would actually try them in.
This is the first place to look when email to a domain starts bouncing after a provider change, when setting up a new mail service and confirming the records took effect correctly, or when simply checking who handles mail for a domain you do not control.
An empty result does not necessarily mean something is broken. A domain with no MX records at all is simply not configured to receive email, which is entirely normal for a domain that only serves a website.
