  • Which campaigns had the highest conversion rate last month?
  • How has email delivery rate trended by week this quarter?
  • Compare open rates across broadcasts versus triggered campaigns
  • Which segments are the largest by number of people?

How Nexatron connects to Customer.io

Whose permissions
Your administrator approves the access the Customer.io connection uses. Where Customer.io supports per-user sign-in, answers run under each person's own access, and Nexatron roles decide who in your company can ask.
Read and write
Questions are read-only: asking never changes Customer.io data.
Setup
Our team sets up the Customer.io connection with your administrator during the pilot. No data migration and no pipeline to build: data is queried where it lives.

Customer.io MCP connector for Claude, ChatGPT and Copilot

Nexatron's hosted MCP server is a governed Customer.io MCP connector: Claude, ChatGPT and Microsoft Copilot ask questions of your Customer.io data through it. Each person signs in as themselves, so the assistant sees only what they may see.

Connect Customer.io to Claude, ChatGPT or Copilot

  1. Connect Customer.io to your Nexatron workspace.
  2. In Claude, add Nexatron from Claude's connector directory. In ChatGPT or Copilot, add a custom MCP connector with the server URL https://api.nexatron.io/api/v1/mcp.
  3. Sign in with your own Nexatron identity (OAuth 2.1), then ask your Customer.io questions.
