What Role Do Secure DNS Servers Play in SPF, DKIM, and DMARC?
Secure DNS servers also support the implementation of email authentication protocols like SPF, DKIM, and DMARC. These protocols use DNS records to validate the authenticity of the email sender, thereby preventing email spoofing and phishing attacks. By ensuring that these records are securely transmitted and received, secure DNS servers enhance the overall security of your email marketing campaigns.
