/shipstar:email-your-users sends real email to real people, so it runs with two hard rules: you see the final draft and the exact audience before anything sends, and each release email can only ever be sent once.

​
Install

Via the official Claude Code plugin (bundles the MCP connection):
Or install the skills standalone from your dashboard’s Agents page (curl -fsSL <APP_URL>/agent-skills/install.sh | sh -s -- <APP_URL>).

​
When to use it

Say “email our users about the release”, “send release notes to the mailing list”, or “let customers know what shipped this week”.

​
What the agent does

  1. Checks the audience first with list_mailing_lists — if no list has active recipients it stops rather than generating an email nobody will receive (recipients are managed in Dashboard → Destinations → Email).
  2. Generates with generate_release_notes_email for the commit window, applying any audience or scope guidance, and polls get_generation_status.
  3. Shows you the full draft and the exact lists and recipient counts, and iterates with update_content.
  4. Sends only on your explicit confirmation via send_release_email — delivery includes per-recipient one-click unsubscribe (RFC 8058), and an already-sent email cannot be re-sent.

​
Requirements

  • Shipstar MCP server connected (see Set up Shipstar)
  • At least one mailing list with active recipients
