Summary
The display of the List-Unsubscribe option in Yahoo Webmail is a multifaceted issue influenced by technical implementation, sender reputation, user engagement, and Yahoo's internal algorithms. Correctly implementing RFC 8058, including DKIM signing of the List-Unsubscribe header, is crucial. Yahoo assesses sender reputation based on factors like spam complaints, engagement metrics (opens, deletes), and authentication (SPF, DKIM, DMARC). User interaction history, such as deleting emails without opening them or marking them as spam, can negatively impact the display of the unsubscribe link. Yahoo also considers email content and may suppress the option if the content triggers spam filters. Testing directly in Yahoo Webmail is essential, as other mail clients may behave differently. Improving overall email deliverability practices, focusing on relevant content, and encouraging user engagement can increase the likelihood of the List-Unsubscribe option being displayed.

The reasons why the list-unsubscribe option might not be showing in Yahoo Webmail are multifaceted, involving technical implementation, sender reputation, user engagement, and Yahoo's own algorithms. Correct implementation of RFC 8058, including DKIM signing, is essential. Yahoo evaluates sender reputation, considering factors like spam complaints and engagement metrics such as opens and deletes.
