Overview

Product-update emails are chronically late because someone has to remember what shipped, translate commit-speak into customer language, and then fight the email tool. This automation does all three: every week it reads merged PRs across your product repositories, writes the newsletter, and creates a draft in Resend through a custom MCP server, ready for review. It’s how we actually generate the ones we send every Friday.
  • Trigger: Schedule
  • Setup time: About 30 minutes

Ingredients

  • A custom automation
  • An environment covering the product repositories
  • The Resend MCP server configured under Settings > Integrations, with a Resend API key
  • A report destination such as #product-updates, so the draft lands in a replyable thread

Steps

  1. Add the Resend MCP server and confirm its tools are available in the environment.
  2. Create a custom automation named Product Updates Newsletter. Choose Custom schedule, enter Mondays at 9am, and select the environment.
  3. Paste the prompt below.
  4. Set the report destination to #product-updates.
  5. Use Run now to generate the first draft, then calibrate its tone by replying in the thread.

Variations

  • Without Resend, remove step 4 and post ready-to-paste Markdown for any email tool.
  • Run monthly with first Monday of the month at 9am.
  • Use separate automations for customer notes and a technical internal changelog.
This recipe showcases custom MCP servers, natural-language scheduling, and replyable automation threads. Review the draft before sending it; the automation is deliberately instructed to create a draft, not send a broadcast. Pairs well with: scheduled housekeeping
