DOMAIN HEALTH DASHBOARD Enter any domain and instantly get a health score. DNS Kit checks your DNS records and email configuration, giving you a clear percentage score so you know exactly where things stand. Save multiple domains and track their health over time.

DNS RECORD LOOKUP Query all major DNS record types — A, AAAA, CNAME, MX, TXT, SOA, PTR, and more. See TTL values, IP addresses, and full record details in a clean, readable format.

EMAIL HEALTH SCANNER Run deep scans on your domain's email setup:

• SPF records — verify sender authorization
• DKIM records — confirm email signing
• DMARC policies — check email authentication
• MX records — validate mail server configuration
• Mail server connectivity — DNS resolution, reverse DNS, hostname matching, SMTP connection, TLS support, and open relay detection
• Blacklist status — check if your mail server is listed

Get a detailed report with pass/fail indicators for every check, plus a full SMTP transcript for debugging.

DNS PROPAGATION CHECKER Changed your DNS records? Track propagation across 23 servers worldwide. See a global map showing which servers have updated and which are still serving old records. Filter by record type and watch propagation happen in real time.
