Audit Campaign Metrics in Claude Desktop

This MCP Server exposes `get_campaign_stats` and `get_campaign_details` to pull real-time open rates and click counts straight into your Claude Desktop workspace. Your agent reads these metrics directly, letting you skip the manual export steps and jump straight into drafting your next newsletter. You get immediate access to your top-performing email layouts without leaving your chat window. Combining `list_recent_campaigns` with these stats lets you quickly spot which subject lines actually got people to click today.

Manage Lists with the Claude Desktop MCP Server

Managing lists becomes straightforward when using `create_contact` and `list_mailing_lists` to sort new signups and assign them to the right segments from your chat interface. Instead of bouncing between tabs, your agent handles the list organization based on your plain-text instructions. Verify who is active and update their list memberships before sending your next big announcement using `list_contacts` to clean up your audience groups.

Instantly Search and Inspect Subscriber Profiles

Spot-check individual subscriber details instantly using `search_contacts_by_email` and `get_contact_details` right inside your chat window. Your agent pulls up custom fields and mailing list history the second you ask about a specific user. If a customer asks why they stopped getting updates, check their status using `get_account_summary` alongside their contact profile to keep your support and marketing data aligned.
