About this tool
The TXT Record & SPF/DKIM Inspector tool fetches all text DNS records for a domain and automatically parses SPF (Sender Policy Framework) mechanisms, DKIM public keys, and DMARC spoofing defense policies.
How to use
Enter domain name
Type a domain name like example.com.
Optional DKIM selector
Specify a DKIM selector (e.g. google or s1) to inspect selector._domainkey.domain.
Review Security Audit
Check SPF mechanism flags, DMARC enforcement policy, and DKIM key validity.
Use cases
