What is SPF Checker?

An SPF (Sender Policy Framework) checker is an essential online tool that helps verify and validate your domain's SPF records. It analyzes your DNS records to ensure your email authentication is properly configured, helping prevent email spoofing and improving your domain's email deliverability. By scanning your SPF configuration, this tool helps identify potential issues that could cause your legitimate emails to land in spam folders or get rejected by receiving servers.

Instant SPF Record Validation

Our tool performs real-time analysis 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 syntax errors, 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.
