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.
