This free MX lookup tool checks the MX records for any domain and shows every mail server that accepts email for it, along with each server’s priority number. MX records are DNS entries that tell other mail servers where to deliver your email. A lower priority number means higher preference, so a server at priority 10 is tried before one at priority 20. If a domain returns no MX records, it cannot receive email and messages sent to it will bounce. Use this MX checker to confirm your domain points to the right mail servers, such as Google Workspace or Microsoft 365, before you send a campaign.
Enter the domain into the MX lookup above and it queries live DNS for that domain’s MX records. A valid result lists at least one mail server with a priority number, for example a Google Workspace domain shows servers ending in google.com. If the tool returns no MX records, email cannot be delivered to that domain and you need to add an MX record at your DNS host before sending or receiving mail.
