Free MX Record Checker & Mail Server Diagnostics

MX Records

Check your domain's MX records instantly. Inspect mail server routing, verify priority settings, view TTL propagation, and troubleshoot email delivery issues.

Ready to Inspect

Enter a domain name in the sidebar to perform a live, real-time DNS lookup for MX, SPF, and DMARC records.

Why Use MX Record Checker?

Troubleshoot email delivery issues instantly. Verify that your domain's mail servers are properly routed and authenticated directly from your browser without using complex command-line tools.

Real-Time DNS Lookup

We query global DNS servers over HTTPS in real-time to fetch the exact, live Mail Exchange (MX) records currently active for your domain name.

SPF Record Validation

Missing SPF records cause your emails to land in spam. We automatically scan your domain's TXT records to detect and validate your Sender Policy Framework.

DMARC Policy Check

Ensure your brand is protected against spoofing. We query the `_dmarc` subdomain to verify if you have a strict DMARC policy in place.

Instant Diagnostics

Our smart analyzer reads the fetched records and provides clear, human-readable warnings if your email routing is misconfigured or lacks redundancy.

Priority & TTL Insights

View the exact routing priority of your mail servers to ensure primary servers receive mail first, along with TTL (Time To Live) propagation data.

Client-Side Engine

This tool uses direct DNS-over-HTTPS (DoH) APIs from your browser. Your queries are fully private and are never logged or stored on our servers.

Done!
