Use this free MX Record Lookup tool to check the mail exchange records for a domain and see which servers are configured to receive email for it. It is useful for troubleshooting email delivery problems, verifying mail provider setup, checking migration changes, reviewing priority values, and confirming whether a domain is pointed to the expected mail service before deeper SMTP or inbox troubleshooting.
MX Record Lookup is useful for quick network checks, validation, and troubleshooting when you want a simple browser-based result.
An MX record lookup shows which mail servers are configured to receive email for a domain and what priority each one has.
MX Record Lookup focuses only on mail exchange records, while DNS Lookup provides a broader view of multiple DNS record types.
Yes. MX records often reveal which mail service or provider is handling incoming email for the domain.
Priority values help determine which mail server should be tried first and which ones act as backups.
It may mean the domain does not have explicit MX records configured, or the lookup failed because of DNS or domain issues.
Yes. Mail can still fail because of TXT-related policies, provider settings, mailbox issues, or broader DNS and routing problems.
Yes. It is one of the fastest ways to confirm whether the new mail routing is visible.
MX records control incoming mail routing, while A records map hostnames to IP addresses for general network resolution.
Yes. It is useful for confirming that a domain points to the expected provider's mail servers.
Use DNS Lookup when you need a broader record overview, especially if the issue may involve TXT, NS, or other DNS records beyond MX.
MX Record Lookup is useful for quick network checks, validation, and troubleshooting when you want a simple browser-based result.
Start by checking the input format, removing accidental spaces or unsupported characters, and comparing your input against the example pattern on the page.
Fix: MX records are only one part of mail setup. TXT, SPF, DKIM, DMARC, mailbox provisioning, and provider-side settings may also matter.
Fix: Check both the mail hostnames and their priority order to understand primary and backup routing.
Fix: Allow time for propagation and caching, especially after migration or provider changes.
Fix: MX records control incoming mail routing, not website resolution.
Fix: Use MX as a routing check, then continue with broader mail diagnostics if delivery still fails.
