Summary
The collective resources paint a comprehensive picture of DMARC and BIMI. Experts and marketers highlight that DMARC prevents domain impersonation, requiring careful management and a strong understanding of SPF and DKIM. Starting with a 'p=none' policy for DMARC is advised to monitor reports before enforcement. BIMI enhances brand recognition and requires DMARC with an enforcing policy and a Verified Mark Certificate. Several resources offer guides, tools, and services for DMARC implementation, emphasizing continuous monitoring, configuration testing, and alignment between email infrastructure and policies. The BIMI Group provides the technical details, dmarcian aids in record understanding, and RFC Editor outlines the official specs. Engaging an ESP is recommended for technical assistance, and reporting tools should be employed for authentication results.
