MX Record Lookup
MX record lookup shows which servers accept email for a domain. Without MX, messages hard bounce and damage sender reputation at scale. Our free tool queries live DNS for MX priorities, hostnames, SPF TXT records, and other TXT entries. IT teams debug delivery; marketers validate domains; developers confirm company emails at onboarding. MX lookup is essential before outreach and pairs with SPF and DMARC tools for authentication audits. Enter any domain for instant results—no software install required.
