Summary
Diagnosing Yahoo deliverability issues during IP warming with a new SFMC instance requires a multifaceted approach. It's common to experience deliverability challenges initially with Verizon Media Group (Yahoo/AOL/Verizon). A best practice is to follow Salesforce's structured IP warming schedule, sending emails to your most engaged subscribers first and gradually increasing volume. Monitoring deliverability metrics like blocklist status, sender score, complaint rates, and engagement data (open rates, click-through rates) is crucial. Ensure proper email authentication (SPF, DKIM, DMARC) and good list hygiene by removing inactive addresses. Checking Yahoo's postmaster tools for feedback loops and understanding SMTP bounce codes can provide valuable insights. Effective list segmentation, personalization, and highly relevant content are key to reducing spam complaints. Implementing feedback loops (FBLs) to remove complaining subscribers and regularly monitor sender reputation are also essential.
