Check DNS records for any domain — MX, A, NS, TXT, and CNAME. Instant results from global DNS resolvers.
An MX (Mail Exchange) record is a DNS record that specifies which mail server is responsible for receiving email on behalf of a domain. MX records point to the server that handles email for a domain and include a priority value — lower numbers have higher priority.
Enter the domain name in the MX Lookup tool above and click Lookup. The tool will query DNS servers and display all MX, A, NS, TXT, and CNAME records for that domain instantly.
MX records tell the internet where to deliver email for your domain. Without correct MX records, email sent to your domain will bounce or be undeliverable. They are essential for any domain that receives email.
TXT records hold text data including SPF (sender verification), DKIM (email signing), and DMARC (authentication policy) records. These protect your domain from email spoofing and improve deliverability.
