Spam Resource Articles from 2026

2026: I've focused heavily on evolving the deliverability and authentication standards around DKIM2, DMARCbis, BIMI logos, and the new APRF feedback framework. I've also tracked major mailbox provider updates -- Microsoft, Apple, Google and more, regulatory shifts (EU pixel tracking rules), and practical deliverability troubleshooting guides.
