> We can only guestimate the impact: > 1,500 downloads every single week > Being conservative, maybe 20% are actively in use > That's about 300 organizations > Each one probably sending what, 10-50 emails daily? > We're talking about 3,000 to 15,000 emails EVERY DAY flowing straight to giftshop.club Those figures seems crazy to me. They assert that behind a single download from NPM is a unique organization. That's insane. A download from NPM is just someone (most often something) doing _npm i_. Given how most CIs are (badly) configured in the wild, they'll _npm i_ at least once per run. If not per stage. So those 1,500 downloads per week can come from just 2 organizations, one with a dev POCing the tool, and one with a poorly configured CI. And the official repo has 1 watch 0 fork and 2 stars: https://github.com/ActiveCampaign/postmark-mc

p Sure the issue raised around MCP and supply chain is big, but the actual impact of this one is probably close to 0.
