The Mailchimp integration lets your ChatRos automations add or remove customers from your Mailchimp audiences and apply or remove tags — all triggered by real conversations, with no manual work.

​
Prerequisites

  • A Mailchimp account with at least one Audience created
  • A Mailchimp API key (found in your Mailchimp account settings)
Your Mailchimp API key must include the datacenter suffix — for example, abc123def456-us21. If yours doesn’t look like this, regenerate it from the Mailchimp dashboard.

​
Connecting Your Account

1

Open Integrations

In your agent’s sidebar, click Integrations. You’ll see the integrations hub with all available providers.
2

Select Mailchimp

Click the Mailchimp card. If you have existing integrations they’ll be listed here.
3

Add New Integration

Click Add Integration, then fill in:
  • Name — A label to identify this connection (e.g., “Main Store List”)
  • API Key — Your Mailchimp API key including the -us21 style suffix
Click Connect. ChatRos will verify the key against your Mailchimp account.
4

Integration Ready

Once connected, your Mailchimp audiences become available in any automation’s Mailchimp action node.

​
Available Actions in Automations

Once connected, you can use four Mailchimp actions inside any automation workflow:
All Mailchimp actions are silently skipped if {{customerEmail}} is not available in the conversation. Make sure your trigger or an upstream form node collects the customer’s email first.

​
Using Mailchimp in a Workflow

  1. In the automation editor, add an Action node
  2. Set the action type to Mailchimp
  3. Select the integration from the dropdown
  4. Choose the sub-action (Add to List, Remove from List, Add Tag, Remove Tag)
  5. Select the target audience (or enter a tag name)
  6. Save and activate the automation
For example, a Conversation Started trigger → Reply with form (collect email) → Mailchimp: Add to List workflow will subscribe every new visitor who provides their email.

​
Managing Integrations

  • Toggle Active/Inactive — Pause a connection without deleting it. Inactive integrations are skipped during automation execution.
  • Delete — Removing an integration that is currently used by an active automation rule is blocked. Deactivate or update the automation first.
  • API Key — API keys cannot be updated after creation. To change a key, delete the integration and create a new one.
Deleting a Mailchimp integration is permanent. Any automation rules that reference it will fail until you update them with a new integration.
