Automate Campaign Reporting in CI

Set up a cron job that runs a simple shell script. Use Claude Code to hit the `list_marketing_campaigns` tool, pipe the output to find the latest campaign, and then call `get_campaign_performance` to get its stats. You can then pipe that JSON output to `jq` for parsing and send a summary to a Slack channel. It’s a fully automated, headless reporting system for your Mailjet activity. No manual logins required.

Script Contact List Backups

Your contact lists are valuable. You can use Claude Code to back them up. A simple command can invoke the `list_subscriber_lists` tool to get all list IDs. Then, loop through those IDs and call `list_all_contacts` for each, redirecting the output to a timestamped CSV file. Schedule it with cron and you have automated, daily backups. This Mailjet MCP server makes that a one-liner.

A Command-Line Mailjet Client

This MCP server turns Claude Code into a powerful, scriptable Mailjet client. Need to quickly add a test user? Run a command that calls `create_new_contact`. Need to check if a user is on a specific list? Chain `list_all_contacts` with `grep`. You can even send transactional emails from a bash script. Just construct the JSON for `send_transactional_email` and pipe it to Claude Code. It's perfect for system alerts or automated notifications from your backend services.
