What Are SPF Records?

SPF (Sender Policy Framework) records are a type of DNS record used to authenticate emails sent from your domain. They help verify that the mail servers sending emails on behalf of the domain are authorized to do so, which prevents email spoofing and improves email deliverability. Stored as TXT records in your domain’s DNS settings, SPF records define rules specifying which IP addresses or mail servers are allowed to send emails using your domain. Properly configured SPF records are a crucial part of modern email security protocols, working alongside DKIM and DMARC to safeguard your domain’s reputation and enhance email deliverability.

Instant SPF Record Validation

Our tool performs a real-time SPF check of your domain’s SPF records, providing immediate feedback on syntax errors, misconfiguration issues, and validation status. This helps you quickly identify and fix problems that could affect your email delivery success rate.

Comprehensive Error Detection

The checker thoroughly examines your SPF records for common mistakes, including errors in the SPF record's syntax, missing entries, and excessive DNS lookups. It provides clear, actionable explanations of any issues found, making it easy for both technical and non-technical users to understand and resolve problems with their SPF configuration.

Best Practice Recommendations

Beyond basic validation, our tool offers practical suggestions to optimize your SPF records according to current email authentication best practices. This includes recommendations for proper record formatting, handling multiple domains, and maintaining optimal lookup limits for better email deliverability. Additionally, it is crucial to adhere to the SPF specification, which limits the number of DNS lookups to 10, as exceeding this limit can lead to email delivery issues and may cause legitimate emails to fail basic SPF record authentication.
