You're spot on that PMF solves many deliverability issues—if people actually want the thing, they'll dig it out of the 'Promotions' folder. But my technical curiosity is about the gap before that: if a startup does have something genuinely useful for a specific person, are they even getting the chance to be seen? It feels like the 'noise' from low-quality AI pitches has forced ISPs to move to a 'guilty until proven innocent' model for any external domain. Google definitely benefits from that shift, as it pushes everyone back toward their walled garden of ads.
