email-and-newsletter skillA

email-and-newsletter is agent-read markdown (skill) from social-media-skills/skills: Email and newsletter strategy for creators and brands — the owned-audience layer that social feeds. Use when someone wants to "start/grow a newsletter," "build an email list," "turn followers into subscribers," "should I use Substack/beehiiv/LinkedIn," "repurpose my newsletter into social (or vice versa)," or build the audience layer social can't take away. Runs email (habit) + a web archive (discovery) off the same work and loops content social<->email. Uses the INBOX framework. Reads brand-pro.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add social-media-skills/skills/email-and-newsletter@v1.0.0
Exact content
mdr add social-media-skills/skills/email-and-newsletter@sha256:0922ac47306fc9a0

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
