Will privacy regulations continue to tighten?

Privacy regulations will likely continue tightening, affecting email deliverability through consent requirements, tracking limitations, and data handling obligations. GDPR precedents inform regulations emerging in other jurisdictions.

Tracking restrictions like Apple's MPP may expand as other platforms implement similar protections. Senders will need metrics strategies that rely less on passive tracking and more on explicit engagement signals and conversion data.

Consent verification may become more technically enforced rather than policy based. Future systems might require cryptographic proof of consent before accepting messages, shifting from after the fact enforcement to pre delivery verification.
