Understanding SPF Records

SPF (Sender Policy Framework) is an email authentication method that helps prevent email spoofing by specifying which mail servers are authorized to send emails on behalf of your domain.

description SPF Record Format: SPF records are TXT records that start with "v=spf1" and contain mechanisms like "include:", "a:", "mx:", and end with an "all" qualifier.
settings Common Mechanisms: Use "include:" for third-party services, "a" and "mx" for your own servers, and "ip4"/"ip6" for specific IP addresses.
priority_high All Qualifier: End with "~all" (soft fail), "-all" (hard fail), or "+all" (pass all). Most domains use "~all" for flexibility.
schedule DNS Lookup Limit: SPF has a 10 DNS lookup limit. Exceeding this causes SPF validation to fail, so optimize your record structure.

SPF Best Practices

Follow these guidelines to create effective SPF records that improve email deliverability and security.

check Keep it Simple: Start with essential mechanisms and add complexity gradually. Simpler records are easier to maintain and debug.
check Monitor DNS Lookups: Stay well under the 10-lookup limit. Use our checker to monitor your lookup count as you modify your record.
check Test Changes: Always test SPF changes before deploying to production. Use tools like ours to validate your records.
