SPF is Sender Policy Framework, an email authentication method that helps verify which servers can send for a domain.
Example of SPF
Example: If your email platform sends from your domain, the SPF record should authorize that platform’s sending servers. A missing or incorrect SPF record can hurt trust with inbox providers.
Why SPF matters
It matters because email is one of the few channels a business can own directly. Strong email fundamentals improve trust, deliverability, segmentation, and long-term lead nurturing.
