Responding to Zack Kanter's claim that cold email will die once every inbox has an AI agent gatekeeper, the author argues only the templated blast dies — 200 investors, one paragraph, no fit reasoning.

What survives is a message proving you did the homework: why this specific fund, which two portfolio companies it rhymes with, which one metric matters to them. Agent gatekeepers don't filter for personalization theater; they filter for signal. Build the signal first.
