The project 'Sigmail' (sigmamail.ai) appears to be a defunct ('deadpooled' as of late 2025) AI email personalization tool. While it achieved #1 on Product Hunt in 2022, the current submission contains demonstrably false claims (e.g., 'most people have used my product') and lacks any verifiable metrics. The input data is low-quality, with typos and empty fields, failing to provide evidence of current utility or viability.
