Understanding SPF and How Our Validator Works

Sender Policy Framework (SPF) is an email authentication protocol designed to detect and prevent email spoofing. By specifying which mail servers are permitted to send emails on behalf of your domain, SPF helps protect your domain from being used for sending spam or phishing emails.

Our SPF Record Validator tool checks the SPF record of your domain against the latest standards and requirements. It ensures that your SPF record is correctly configured to enhance your email security and deliverability.

The tool validates the syntax of your SPF record, checks for the number of DNS lookups, and verifies the validity of included domains and IP addresses. By using our validator, you can identify and resolve potential issues, ensuring your emails reach their intended recipients securely.
