Your push "delivered" metric is a mirage — the OS decides who sees it
Your push notification dashboard says "delivered."
The user's device disagrees.
Apple Intelligence now runs a 3B parameter model on every iPhone summarizing, reranking, and quietly suppressing notifications before they render. Google's Gemini Nano does the same through AICore. Both are opaque, unappealable, and completely invisible to your analytics.
Opt-in collapsed from 85% to 67% the moment Android made permission explicit. Most teams still benchmark against the old number.
Segmented campaigns: 16.3% open rate. Broadcast: 4.7%. The model punishes volume at the OS level, before your copy even renders.
Rising engagement metrics? Might mean better messaging. Might mean the platform is only showing you to users it already trusts you with. You can't tell which.
Email went through this exact arc. Marketers trusted open rates until Mail Privacy Protection proved they were a mirage.
Push is one OS update behind email. Most teams won't notice until it's too late.
Are you building for the user who reads your notification, or the model that decides if they see it?
