DMARC adoption is steadily increasing globally, driven by growing awareness of email security threats like phishing and spoofing, the need to protect brand reputation, and the incentive of BIMI adoption. While DMARC might not become a strict requirement soon, aligning with SPF and DKIM for DMARC readiness is a best practice. Benefits include improved deliverability and protection from fraudulent emails. However, implementation costs and business process changes can be significant barriers. Future expectations involve stricter enforcement by mailbox providers and increased importance of DMARC reporting. Starting with DMARC on new domains is easier than retrofitting existing ones. Organizations should aim for full DMARC compliance, even if gradually, and proactively monitor their DMARC reports. Domains with properly configured DMARC records achieve better delivery rates, crucial for domain reputation and sender trust.
