Mailchimp Automation via Rube MCP

Automate Mailchimp email marketing workflows including campaign creation and sending, audience/list management, subscriber operations, segmentation, and performance analytics through Composio's Mailchimp toolkit.

Prerequisites

• Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
• Active Mailchimp connection via RUBE_MANAGE_CONNECTIONS with toolkit mailchimp
• Always call RUBE_SEARCH_TOOLS first to get current tool schemas

Setup

Get Rube MCP: Add https://rube.app/mcp as an MCP server in your client configuration. No API keys needed — just add the endpoint and it works.

1. Verify Rube MCP is available by confirming RUBE_SEARCH_TOOLS responds
2. Call RUBE_MANAGE_CONNECTIONS with toolkit mailchimp
3. If connection is not ACTIVE, follow the returned auth link to complete Mailchimp OAuth
4. Confirm connection status shows ACTIVE before running any workflows

Core Workflows

1. Create and Send Email Campaigns

When to use: User wants to create, configure, test, and send an email campaign.

Tool sequence:

1. MAILCHIMP_GET_LISTS_INFO - List available audiences and get list_id [Prerequisite]
2. MAILCHIMP_ADD_CAMPAIGN - Create a new campaign with type, audience, subject, from name [Required]
3. MAILCHIMP_SET_CAMPAIGN_CONTENT - Set HTML content for the campaign [Required]
4. MAILCHIMP_SEND_TEST_EMAIL - Send preview to reviewers before live send [Optional]
5. MAILCHIMP_SEND_CAMPAIGN - Send the campaign immediately [Required]
6. MAILCHIMP_SCHEDULE_CAMPAIGN - Schedule for future delivery instead of immediate send [Optional]

Key parameters for MAILCHIMP_ADD_CAMPAIGN:

• type: "regular", "plaintext", "rss", or "variate" (required)
• recipients__list__id: Audience/list ID for recipients
• settings__subject__line: Email subject line
• settings__from__name: Sender display name
• settings__reply__to: Reply-to email address (required for sending)
• settings__title: Internal campaign title
• settings__preview__text: Preview text shown in inbox

Key parameters for MAILCHIMP_SET_CAMPAIGN_CONTENT:

• campaign_id: Campaign ID from creation step (required)
• html: Raw HTML content for the email
• plain_text: Plain-text version (auto-generated if omitted)
• template__id: Use a pre-built template instead of raw HTML

Pitfalls:

• MAILCHIMP_SEND_CAMPAIGN is irreversible; always send a test email first and get explicit user approval
• Campaign must be in "save" (draft) status with valid audience, subject, from name, verified email, and content before sending
• MAILCHIMP_SCHEDULE_CAMPAIGN requires a valid future datetime; past timestamps fail
• Templates and HTML content must include compliant footer/unsubscribe merge tags
• Mailchimp uses double-underscore notation for nested params (e.g., settings__subject__line)

2. Manage Audiences and Subscribers

When to use: User wants to view audiences, list subscribers, or check subscriber details.

Tool sequence:

1. MAILCHIMP_GET_LISTS_INFO - List all audiences with member counts [Required]
2. MAILCHIMP_GET_LIST_INFO - Get details for a specific audience [Optional]
3. MAILCHIMP_LIST_MEMBERS_INFO - List members with status filter and pagination [Required]
4. MAILCHIMP_SEARCH_MEMBERS - Search by email or name across lists [Optional]
5. MAILCHIMP_GET_MEMBER_INFO - Get detailed profile for a specific subscriber [Optional]
6. MAILCHIMP_LIST_SEGMENTS - List segments within an audience [Optional]

Key parameters for MAILCHIMP_LIST_MEMBERS_INFO:

• list_id: Audience ID (required)
• status: "subscribed", "unsubscribed", "cleaned", "pending", "transactional", "archived"
• count: Records per page (default 10, max 1000)
• offset: Pagination offset (default 0)
• sort_field: "timestamp_opt", "timestamp_signup", or "last_changed"
• fields: Comma-separated list to limit response size

Pitfalls:

• stats.avg_open_rate and stats.avg_click_rate are 0-1 fractions, NOT 0-100 percentages
• Always use status="subscribed" to filter active subscribers; omitting returns all statuses
• Must paginate using count and offset until collected members match total_items
• Large list responses may be truncated; data is under response.data.members

3. Add and Update Subscribers

When to use: User wants to add new subscribers, update existing ones, or bulk-manage list membership.

Tool sequence:

1. MAILCHIMP_GET_LIST_INFO - Validate target audience exists [Prerequisite]
2. MAILCHIMP_SEARCH_MEMBERS - Check if contact already exists [Optional]
3. MAILCHIMP_ADD_OR_UPDATE_LIST_MEMBER - Upsert subscriber (create or update) [Required]
4. MAILCHIMP_ADD_MEMBER_TO_LIST - Add new subscriber (create only) [Optional]
5. MAILCHIMP_BATCH_ADD_OR_REMOVE_MEMBERS - Bulk manage segment membership [Optional]

Key parameters for MAILCHIMP_ADD_OR_UPDATE_LIST_MEMBER:

• list_id: Audience ID (required)
• subscriber_hash: MD5 hash of lo
