Look up and validate SPF TXT records for a domain. Parse mechanisms, count DNS lookups, and review policy strength.

Look up and validate SPF TXT records for a domain. Parse mechanisms, count DNS lookups, and review policy strength. This SPF Record Checker is part of our free developer tools collection on freetoolstouse. It runs entirely in your browser, so your files and inputs stay on your device unless the tool explicitly performs a network check (for example DNS or SSL lookups). There is no signup, no watermark, and no usage cap. Use it whenever you need a fast, accurate result without installing software.
