About the MX Record Lookup
This free MX record lookup lists the mail servers responsible for receiving email on your domain, ordered by priority, with each server's resolved IP address. MX records tell the world where to deliver your mail - and a missing MX is also a spam signal when you send.
The tool also identifies your mail provider automatically - Google Workspace, Microsoft 365, Zoho and others - so you can confirm your setup matches what you expect.
Frequently asked questions
What is an MX record?
An MX (Mail Exchange) record tells other mail servers which servers accept email for your domain. Records are tried in priority order, lowest number first.
What happens if I have no MX record?
Your domain cannot receive email, and receivers may treat the missing MX as a spam signal when you send, since legitimate businesses can receive replies.
What priority should my MX records have?
Lower numbers are tried first. A primary at priority 10 and backups at 20, 30 is common. The exact values matter less than the order they imply.
