How it works

SPF (Sender Policy Framework) is a DNS TXT record that specifies which mail servers are authorised to send email on behalf of your domain. This tool queries Cloudflare DNS for the SPF TXT record and parses all mechanisms (include, ip4, ip6, a, mx) and their qualifiers (pass, softfail, fail, neutral).
