Strengthen Email Security with SPF, DKIM, and DMARC

Email authentication is essential for ensuring deliverability, preventing spoofing, and maintaining domain trust. In this episode, Nathan Taylor discusses how SPF, DKIM, and DMARC are core technologies that work together to validate sender identity and protect against unauthorized use. DNS and DNSSEC play a foundational role in publishing and securing these records, enabling proper verification across systems. Common misconfigurations, record alignment challenges, and the impact of third-party services are key considerations in maintaining effective authentication. Managing marketing platforms, third-party senders, and internal systems requires alignment with email authentication standards to maintain a secure and reliable email environment.
