Summary
Email campaigns to Yahoo users get deferred due to factors like poor sender reputation, content issues, authentication problems, and temporary server issues. Addressing these requires a multi-faceted approach. Key actions involve improving sender reputation through IP warming, engaging content, and consistent sending. Proper authentication (SPF, DKIM, DMARC), cleaning and segmenting email lists, monitoring bounce and complaint rates, and carefully reviewing email content for spam triggers are crucial. Additionally, analyzing DMARC reports, securing signup sources with CAPTCHA, checking for blacklisting, addressing spam complaints, and analyzing bounce messages can help resolve these issues. Focusing on recipients reporting mail as spam should be a priority.
