Steps to follow
To continue sending emails without issues:
- Use your own domain for sending
- Set up DMARC authentication for this domain
- Create a CNAME to enable custom DKIM signing
- Maintain a low spam rate
Use your own domain
Since February 2024, Gmail and Yahoo have strengthened DMARC verification for their users.
Sending from an @gmail.com or @yahoo.com address through a third-party service no longer passes DMARC validation and may be blocked or marked as spam.
Update: As of April 29, 2025, Microsoft also enforces these requirements for Outlook, with new rules for high-volume senders.
Solution: Use a domain you own and control, for example: yoursite.com or a subdomain like newsletter.yoursite.com.
Benefits:
- More credible and professional emails
- Better deliverability and control
- Ability to customize DKIM signing for your brand
Set up DMARC authentication
DMARC helps secure your emails and protect your domain from spoofing.
- For your messages to pass DMARC validation: The email must be authenticated via SPF or DKIM The From: header must match the authenticated domain
- Gmail recommends starting with the DMARC policy set to none.
Benefits of DMARC:
- Protect your domain against spoofing
- Receive reports about emails sent from your domain
- Meet new Gmail and Yahoo requirements

Create a CNAME for DKIM
Since February 2024, each sending domain must have a custom DKIM signature.
This ensures the visible From: domain aligns with the DKIM signature.
It is required for passing DMARC validation and improving deliverability.
Maintain a low spam rate
To minimize deliverability issues:
- Send only to contacts who gave consent (CASL)
- Segment your lists to deliver targeted and relevant content
- Allow contacts to update their preferences
- Monitor stats, bounce rates, and unsubscribes
- Register your domain with Gmail Postmaster Tools > to track your reputation
