Integrating Yespo with Claude Cowork

The Yespo MCP connector for Claude Cowork connects Claude to your Yespo account through an MCP connection. You can describe tasks in plain language, and the agent can perform approved actions in your account without switching to the Yespo interface.

Once connected, you can work with email templates, contacts, segments, events, workflows, and analytics directly from Claude.

  • Statistics by date, event analytics by day, revenue share calculations

📘 Note

Analytics data is sourced from BigQuery reports and updated once per day. Data for the current day is not yet available — the agent can only access data through yesterday.

  • Get a plain-language description of what a workflow does and how it is built
  • See what messages are inside a workflow

📘

Note

Workflow data is updated once per day. Changes made today will be visible to the agent starting tomorrow.

Limitations

  • Layout and block structure in email templates cannot be changed
  • Dynamic segments are not supported — the connector works with static segments only
  • Creating, launching, and scheduling bulk campaigns are not supported

Always review the agent's changes before publishing.

Requirements

  • An active Yespo account
  • A paid Claude plan (Pro, Max, Team, or Enterprise)
  • Claude Desktop for macOS or Windows (x64)

Installation

  1. In Cowork, go to Customize.
  1. Select Connectors → + → Add custom connector.
  1. Enter https://mcp.yespo.io as the URL and set any name you prefer.

  1. Click Add → Connect, and sign in to your Yespo account when prompted.

Once connected, click Open desktop app to return to Claude Desktop, or close the browser tab and switch back manually.

Tool Permissions

After connecting, you'll see a list of Yespo API tools. By default, the agent asks for confirmation before using each tool. If you prefer to skip these prompts, set individual tools to Always allow.

Verify the Connection

To confirm the setup is working, start a new chat in Cowork and ask:

  • Are any MCP servers connected?

If the agent lists the Yespo MCP server, you're ready to go. Try a first task:

  • Show me my last 5 email templates.

What to Do Next

Once connected, you can start working with your Yespo account through natural language. Here are some example prompts:

Templates and content:

  • Translate email template ID 3935987 into German.
  • Clone template ID 3935987 and update the subject line for a spring sale campaign.
  • Duplicate templates IDs 3935987, 3935988, and 3935989. Add the suffix "— Copy Q2" to each template name.
  • Replace all instances of the old unsubscribe link with the new one across all emails in workflow ID 434661.
  • Extract the subject, preheader, body copy, CTA, and footer from template ID 3935987.

Template QA:

  • Audit all emails in workflow ID 434661 for unsubscribe links. Flag any that are missing or broken.
  • Check the subject line, preheader, and hero image for templates in the "Spring Sale" series. Flag anything incomplete or inconsistent.
  • Template ID 3935987 has mobile rendering issues on iOS. Diagnose and fix the HTML/CSS.

Analytics and performance:

  • Show me the Open and Click metrics for all workflows last month.
  • Which workflows had the highest conversion rate in March?
  • Compare broadcast and triggered workflow performance for Q1.
  • How many PurchaseCompleted events were recorded last week, broken down by day?
  • What is the share of email conversions from total PurchaseCompleted events in March?
  • My open rate is high but CTR is low — what could explain this?
  • Run a deliverability and spam metric audit for campaign IDs 1234, 1235, and 1236.

Contacts and segments:

  • Create a static segment called "Abandoned Cart — April" and add the following contact IDs: 10023, 10045, 10089.
  • Show me the recent message history for contact ID 58821.
  • What communications did contact ID 58821 receive in the last 30 days and why?
  • Contact ID 58821 should be in segment ID 1234 but isn't. Why, and how do I fix it?

Workflows:

  • What is workflow ID 434661 about? Describe its structure and steps.
  • Review all emails in workflow ID 434661 and suggest improvements.
  • Are there any contacts entering two workflows at the same time?
  • Help me set up an A/B experiment in workflow ID 434661. Verify the conversion event is configured correctly.
