What MX records tell you
MX records decide where incoming email for a domain is delivered. A healthy domain usually has one or more mail exchange hosts with clear priorities.
When to use this tool
Run an MX lookup before debugging missing verification emails, testing a temporary email domain, or moving mail to a new provider.
- Confirm whether a domain can receive mail.
- Compare backup mail servers and priorities.
- Spot stale records after provider migrations.
