How to use
SPF records help receiving mail servers decide whether a sender is authorized to send mail on behalf of a domain. Problems like publishing multiple SPF records, forgetting an all mechanism, or using an overly permissive policy can break delivery or weaken protection against spoofing. A structured checker makes those issues easier to spot than reading a raw TXT string alone.
DMARC matters alongside SPF because it defines how mail receivers should handle failures and where reports can be sent. Looking at SPF and DMARC together provides a more complete picture of email authentication health, which is why the tool checks both instead of stopping at the first TXT match.
