Check the mail exchange (MX) records for a domain.
How to Use Domain MX Record Checker
Enter a website domain name (e.g., example.com) in the search box.

Why Use This Tool?
Debug Email Delivery
If you aren't receiving emails, checking your MX records is the very first troubleshooting step.
Verify Email Migration
When moving to a new provider like Google Workspace, verify that the new MX records have propagated globally.
Identify Email Providers
Quickly determine which company handles the professional email hosting for any business.
Understanding Your Results
Priority Number
The lowest number has the highest priority. Senders will try the lowest number first, and use higher numbers as backups.
Mail Exchange
The actual server hostname that handles the incoming mail (e.g., aspmx.l.google.com).
No Records Found
If no MX records exist, the domain is physically incapable of receiving any emails.
