newsletter_builder
shallowio.github.shashwatgtm/craft-content-mcp · Verify this server
Writes a first draft of a newsletter issue from your topic and the action you want readers to take. Optional key points, audience segment, newsletter type, tone, earlier topics and your product fit it to the reader. Returns a subject line and preview, an opening, a short section for each key point, your own call to action as the button, A/B subject lines, alternative opening hooks and sector notes. Without key points it suggests some from the topic and sector. The draft uses only what you gave: it adds no statistic or customer story, and says what it did not get.
