Vault kin (added at capture)

Surfaced by sspaeti (2-tweet, captured) quote-tweeting marclou’s MailCheap.ai launch (“I vibe-coded beehiiv, and it’s 83% cheaper… agentic; everything in the UI is available to your AI”) with the genre-defining reply: “Just use Listmonk, it’s free, open-source, and has been around forever (first commit 2018). Set it up once with AWS SES and you pay $0.10 for 1000 emails.” His SES setup notes — notably published on his own digital brain (ssp.sh/brain, a Quartz/Obsidian setup like this one).

The exchange is a specimen of the 2026 dynamic: the vibe-coded product launch vs the boring-incumbent reply — MailCheap is Dub/DubCo-founder Marc Lou’s agentic-newsletter play; listmonk is the “already solved, single binary, ~$0/month” answer with an 8-year head start. Kin to the What matters in AI world quality-subsidy lane (Collison: agents reward products that are actually good AND cheap) and Static Site Generators’s maintenance-mortality lesson (2018 first commit = the survivor class).
