What are potential future changes in email deliverability?

Potential future changes in email deliverability point toward increased authentication requirements, tighter engagement based filtering, and more sophisticated AI powered personalization. The trajectory established by Gmail and Yahoo's 2024 requirements suggests continued tightening.

Authentication may evolve to require stricter DMARC policies (p=reject as baseline), wider BIMI adoption for visual verification, and potentially new standards addressing current gaps. Engagement weighting may increase as providers refine AI models.

Privacy regulations continue shaping deliverability through consent requirements and tracking limitations. Future changes likely reflect balance between user protection, legitimate sender needs, and technological capabilities for verification and personalization.
