Perplexity

Check Campaign Health Instantly

This toolset plugs directly into your Customer.io account. You can ask Claude to check the numbers on any campaign using `get_campaign_performance` or see what's currently running with `list_active_campaigns`. Forget logging into another dashboard. You just ask a question in plain English, and the answer appears. It’s perfect for getting a quick status update during a meeting or just before you push a new feature live.

Manage Users and Segments in Claude Desktop

Pull up customer information without leaving your chat window. The `get_customer_details` tool fetches a specific user's profile, while `list_audience_segments` and `list_segment_members` let you inspect how your audiences are defined. This is a huge time-saver for support and product teams. When you get a bug report, you can ask Claude to pull the user's record on the spot. No more context switching or searching through another system.

Trigger Emails and Broadcasts

This MCP Server isn't just for reading data—it takes action. You can send a test password reset with `send_transactional_email` or kick off a full marketing campaign with `dispatch_broadcast`. Having these tools in Claude turns your agent into an active part of your operations. It can respond to events, run tests, and manage communications, all based on your instructions.
