Where does email go?
Enter a domain to see its mail servers (MX), each one's priority, and whether email delivery is routed correctly.
About this tool
The MX (Mail Exchange) record decides which server should receive email sent to your domain. A lower priority number means higher preference. A misconfigured MX record is the most common reason email doesn't arrive — this tool shows you whether your records are set up correctly.
Frequently asked questions
What is an MX record?
A DNS record that names the server responsible for receiving a domain's email.
What is the number next to the MX record?
The priority — the server with the lowest number is tried first, the rest act as backups.
Why isn't my email arriving?
Usually a missing or wrong MX record (or the mail server's A record); check SPF/DKIM too.
