What are the main rules any DMARC must have to accomplish new Gmail and Yahoo requirements?
Summary
What email marketers say9Marketer opinions
Email marketer from Mailjet shares that DMARC policies should be set to 'quarantine' or 'reject' to fully comply with new requirements and actively prevent unauthorized use of your domain. Monitoring DMARC reports is essential to identify and address any authentication issues.
Email marketer from Reddit explains the importance of consistent DMARC monitoring to identify authentication issues and unauthorized sending sources. Use DMARC reporting tools to analyze reports and promptly address any failures.
Marketer from Email Geeks shares if the domain only sends email from one place, and it's properly authenticated, then you can probably adopt a stronger DMARC policy, but ensure this by analyzing the DMARC reports first.
Email marketer from EmailOctopus says that properly configuring SPF and DKIM records is a prerequisite for implementing DMARC effectively. Ensure both SPF and DKIM are correctly set up to authenticate your email and improve deliverability.
Email marketer from Postmark shares including 'rua' and 'ruf' tags in your DMARC record to receive aggregate and forensic reports. These reports provide valuable insights into email authentication performance and potential security threats.
Marketer from Email Geeks explains that DMARC policy depends on whether the From domain is used in many places or just one. If many, ensure they're all authenticated before adopting a policy other than "none." Ensure the DMARC record allows all of them to send authorized email.
Marketer from Email Geeks states the safest bare minimum DMARC record to comply with new requirements is "v=DMARC1; p=none;”.
Email marketer from Validity states ensuring proper SPF and DKIM alignment with your 'From' domain is critical for DMARC compliance. Mismatched alignment can lead to authentication failures and deliverability issues, especially with stricter Gmail and Yahoo requirements.
Email marketer from SparkPost responds that implementing DMARC helps improve email deliverability by providing feedback on authentication failures. Regularly reviewing DMARC reports enables senders to adjust their configurations and ensure proper authentication.
What the experts say4Expert opinions
Expert from Spam Resource explains that to comply with new Gmail and Yahoo requirements, DMARC policies must be set to either 'quarantine' or 'reject' to instruct recipient servers on how to handle unauthenticated emails. They emphasize the importance of monitoring DMARC reports to identify and address any deliverability issues.
Expert from Word to the Wise shares that DMARC alignment is critical for meeting new email authentication requirements. Ensuring that SPF and DKIM records align with your sending domain significantly improves email deliverability and prevents fraudulent use of your domain.
Expert from Email Geeks explains the main effect of DMARC on deliverability is to make it worse, and you should not deploy DMARC with anything other than p=none until you understand the impact.
Expert from Email Geeks shares you need an rua flag too, pointing at a legitimate report handler.
What the documentation says4Technical articles
Documentation from Yahoo Mail requires senders to authenticate their email using SPF or DKIM. They also advise implementing DMARC records that align with your sending practices to protect your domain's reputation and improve deliverability to Yahoo Mail users.
Documentation from RFC Editor shares that the DMARC standard (RFC 7489) specifies that DMARC policies define how recipient mail servers should handle emails that fail DMARC checks. This standard is foundational for understanding DMARC implementation and compliance.
Documentation from DMARC.org explains that a DMARC record must include a 'p=' tag specifying the policy (none, quarantine, or reject). Choosing 'quarantine' or 'reject' is crucial for meeting stricter requirements, with 'reject' offering the highest level of protection against domain spoofing.
Documentation from Google Workspace Admin Help explains that to meet Google's requirements, DMARC must be set up with a policy of either p=quarantine or p=reject. This ensures that unauthenticated mail is either quarantined or rejected, providing strong protection against spoofing.
