Frequently asked questions about MX Lookup
MX records tell other mail servers where to deliver email for a domain. The number is the priority: lower wins, so mail is tried against the lowest-priority server first, with the higher ones acting as backups. Equal priorities share the load. This tool lists them in priority order and resolves each server's IP addresses so you can confirm they point where you expect.
The query runs on Uptimeify's EU servers, not in your browser, the domain you enter is sent to us only to perform the lookup and is not stored. As an EU-built, EU-hosted provider, Uptimeify keeps this off US infrastructure and clear of US Cloud Act exposure, which matters for agencies handling client data under GDPR.
Missing or misconfigured MX records mean lost email: often noticed only when a customer complains. Verify a domain's mail servers here, then let Uptimeify monitor your mail and DNS continuously and alert you the moment delivery is at risk.
