https://asmar.momand.dev/blog Notes from the keyboard — software architecture, AI-first engineering, ADRs, and the systems I'm building. en Next.js + Keystatic https://asmar.momand.dev/blog/a-newsletter-without-a-newsletter-provider https://asmar.momand.dev/blog/a-newsletter-without-a-newsletter-provider Sun, 31 May 2026 00:00:00 GMT No free managed tier will email your list the moment you publish — that's the feature kept behind the paywall. So I didn't rent it. This site's newsletter is three small pieces I already run for free: a static form, a serverless function that holds the API key, and a CI job that broadcasts on publish.

Here's the standard I wrote to close the door — and why ULID won.

When every service rolls its own clock port, you get six file paths and three interface names for one concern. The fix is one platform port — and the testability it unlocks.

Treating it as foundational architecture — a single governed gateway, provenance on every artifact — changes what you can promise. AI-firstArchitectureGovernanceDDD
