Summary
Managing SFMC email delivery issues in Yahoo with delays and no bounces requires a multi-faceted approach. Experts and marketers emphasize factors such as sender reputation, authentication (SPF, DKIM, DMARC), content quality, and subscriber engagement. Yahoo's engagement-based filtering means subscriber interaction directly impacts deliverability. Troubleshooting involves checking SMTP settings, IP reputation (using tools like AboutMyEmail), reviewing Yahoo's postmaster resources, and verifying compliance with Yahoo's bulk email policies. Techniques like list segmentation, IP warming, compelling preview text, and participation in feedback loops can also improve deliverability. If emails are neither bouncing nor in the inbox or spam folder, SFMC may have declined to send them. RFC documentation highlights the importance of correct SPF configuration, while Salesforce documentation details bounce management, SAP implementation, and DMARC setup.

What the experts say
5 expert opinions
Addressing SFMC email delivery delays to Yahoo, even without bounces, requires examining various factors. Key areas to investigate include Yahoo's handling of accepted mail (potential queueing), sender reputation (using tools like AboutMyEmail), compliance with Yahoo's bulk email policies, and subscriber engagement. If the bounce data view doesn't show bounces and the email isn't in the inbox or spam folder, SFMC may have declined to send the email. Addressing issues such as poor authentication, list management, or content relevance can improve deliverability. Yahoo's engagement-based filtering means subscriber interaction heavily influences inbox placement, encouraging targeted content and suppression of inactive users.
Key opinions
- Yahoo Handling: If Yahoo accepts the email but delivery is delayed, the email is likely queued; check logs to verify.
- Sender Reputation: If there are no bounces and delays impact sends and tests, Yahoo doesn't think highly of the email so you need to ensure everything is configured correctly.
- SFMC Decline: If there are no bounces and the email is not present in the inbox/spam, SFMC may have declined sending the email.
- Bulk Email Policies: Compliance with Yahoo's bulk email policies is crucial, focusing on authentication, list management, and engagement.
