What is SPF Lookup for?

Extracts SPF records from TXT records to identify which sources may send mail for a domain. The output is organized for quick review, copying, and cross-checking with nearby tools in the Email Security group.

How this tool works

SPF data is read from TXT records that start with v=spf1, then mechanisms such as include, ip4, ip6, a, mx, exists, all, and redirect are inspected. The goal is to reveal lookup cost, policy intent, and common mistakes that affect sender authentication.
