Summary
The new Gmail and Yahoo changes strongly emphasize email authentication, particularly DMARC alignment, for senders using branded domains. For those already following best practices, including correct SPF, DKIM, and DMARC setup, the changes should improve deliverability by filtering out unauthenticated email. However, senders lacking proper authentication or with misconfigured settings risk deliverability issues, such as emails being rejected or marked as spam. Google's requirements apply to senders sending over 5,000 messages a day. Domain owners must actively monitor DMARC reports, maintain a good sender reputation, and ensure all authentication records are correctly configured. A correct setup also involves using the appropriate 'from' domain and also ensuring DMARC is configured if using subdomains.
Key findings
- Improved Deliverability (If Compliant): Senders with proper DMARC, SPF, and DKIM setup can expect improved deliverability.
- Authentication is Non-Negotiable: Gmail and Yahoo now require email authentication using SPF, DKIM, and DMARC.
- Negative Impact (If Not Compliant): Without DMARC alignment, emails may be rejected or sent to the spam folder, harming domain reputation.
- Proactive Monitoring is Crucial: Actively monitor DMARC reports to identify and address any authentication issues and test configuration.
- Subdomains Must Also Comply: If using subdomains for sending, ensure they are also properly authenticated with SPF, DKIM, and DMARC.
Key considerations
- Implement Email Authentication: Ensure SPF, DKIM, and DMARC are correctly configured for your sending domain.
- Monitor DMARC Reports Regularly: Actively track DMARC reports to identify and resolve authentication failures.
- Maintain Sender Reputation: Send engaging, relevant content to maintain a positive sender reputation.
- Review Email Sending Strategy: Re-evaluate your email strategy if you are not yet compliant with the new requirements.
- Consider Authentication Domain: Assuming the authentication domain (DKIM and/or return-path) is the sending domain.

3 expert opinions
The expert opinions suggest that if senders are using a branded domain and have implemented proper email authentication including SPF, DKIM, and DMARC, the new Gmail/Yahoo changes will likely have a positive impact by filtering out unauthenticated email and improving deliverability.

- Positive Impact with Authentication: DMARC alignment in place yields a positive impact due to filtering of unauthenticated emails.
- Branded Domain Advantage: Using a branded domain with proper configuration (DKIM, Return-Path) ensures compliance.
- Strategic Re-evaluation: Lack of full authentication warrants a strategic overhaul to meet new requirements.
Key considerations
- Domain Authentication: Verify that SPF, DKIM, and DMARC are correctly configured.
- Email Strategy: Re-evaluate email strategy if domain authentication isn't properly configured.

What the documentation says
4 technical articles
The documentation from Google, Yahoo, RFC and DMARC.org highlights the necessity of email authentication (SPF, DKIM, and DMARC) for senders, particularly those sending a high volume of emails. DMARC builds upon SPF and DKIM to provide domain-level policies and reporting, enabling domain owners to control how email receivers handle unauthenticated emails. Proper DMARC setup requires prior SPF and DKIM configuration, followed by publishing a DMARC record in the DNS.
Key findings
- Authentication Mandatory: Gmail and Yahoo require senders to authenticate emails using SPF, DKIM, and DMARC.
- DMARC Functionality: DMARC builds on SPF/DKIM to add domain-level policy and reporting.
- DNS Record Required: DMARC setup involves publishing a DMARC record in the DNS.
- Volume Threshold: Google's requirements apply to senders sending over 5,000 messages a day.
Key considerations
- Prior Setup: SPF and DKIM must be set up before configuring DMARC.
- Policy Control: Domain owners can specify how receivers handle unauthenticated emails.
