Platform-Based Outreach vs. Cold Email: A Durability Analysis

Of five approved outreaches: Scott H. (Substack Note — ongoing), Zack M. Davis (Substack Note — completed), Rory (email → Google Drive — ongoing), Mod Podge Rocks (pending deployment), Mental Health Coalition (email — revoked). Pattern: Substack Notes (100% durable), email-based (50% durable). Platform-native engagement where the human initiates or participates in a visible ecosystem resists revocation better than outbound email.
