What the experts say
5 expert opinions
Experts suggest that the timeline for Gmail fully enforcing a DMARC quarantine policy remains uncertain. While initial deadlines, such as February 2024, were set for compliance with authentication requirements, a hard date for quarantine implementation is not definitively known. Google provides limited information regarding updates, making it difficult to predict the exact timing. The subdomain policy is currently set to quarantine, but broader enforcement hinges on factors like reducing ESP-sent mail using Gmail addresses. Proactive email authentication and reputation management are crucial, along with ongoing monitoring.
Key opinions
- Unclear Timeline: The specific timeline for Gmail's full DMARC quarantine enforcement is not clearly defined.
- Limited Information: Google is not providing early notifications or detailed information about upcoming DMARC policy changes.
- February 2024 Deadline: February 2024 was a key compliance deadline for initial authentication requirements, though not necessarily for full quarantine enforcement.
- Subdomain Quarantine: The Gmail DMARC record has a subdomain quarantine policy configured.
Key considerations
- Proactive Measures: Implement strong email authentication practices (SPF, DKIM, DMARC) to protect your domain and reputation.
- Reputation Management: Focus on building and maintaining a positive sender reputation to avoid deliverability issues.
- Ongoing Monitoring: Continuously monitor your email performance and DMARC reports to identify and address any potential problems.
- Future Policy: It is expected that a more broad policy will be implemented sometime in 2024.
