# Mailchimp Automation via Rube MCP

## Overview

This public intake copy packages `plugins/antigravity-awesome-skills-claude/skills/mailchimp-automation` from `https://github.com/sickn33/antigravity-awesome-skills` into the native Omni Skills editorial shape without hiding its origin.

Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.

This intake keeps the copied upstream files intact and uses the `external_source` block in `metadata.json` plus `ORIGIN.md` as the provenance anchor for review.

# 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.

Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: Prerequisites, Common Patterns, Known Pitfalls, Limitations.

## When to Use This Skill

Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.

- This skill is applicable to execute the workflow or actions described in the overview.
- Use when the request clearly matches the imported source intent: Automate Mailchimp email marketing including campaigns, audiences, subscribers, segments, and analytics via Rube MCP (Composio). Always search tools first for current schemas.
- Use when the operator should preserve upstream workflow detail instead of rewriting the process from scratch.
- Use when provenance needs to stay visible in the answer, PR, or review packet.
- Use when copied upstream references, examples, or scripts materially improve the answer.
- Use when the workflow should remain reviewable in the public intake repo before the private enhancer takes over.

## Operating Table

| Situation | Start here | Why it matters |
| --- | --- | --- |
| First-time use | `metadata.json` | Confirms repository, branch, commit, and imported path through the `external_source` block before touching the copied workflow |
| Provenance review | `ORIGIN.md` | Gives reviewers a plain-language audit trail for the imported source |
| Workflow execution | `SKILL.md` | Starts with the smallest copied file that materially changes execution |
| Supporting context | `SKILL.md` | Adds the next most relevant copied source file without loading the entire package |
| Handoff decision | `## Related Skills` | Helps the operator switch to a stronger native skill when the task drifts |

## Workflow

This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow.

#### Imported: 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 lowercase email (required)
- `email_address`: Subscriber email (required)
- `status_if_new`: Status for new subscribers: "subscribed", "pending", etc. (required)
- `status`: Status for existing subscribers
- `merge_fields`: Object with merge tag keys (e.g., `{"FNAME": "John", "LNAME": "Doe"}`)
- `tags`: Array of tag strings

**Key parameters for MAILCHIMP_ADD_MEMBER_TO_LIST**:
- `list_id`: Audience ID (required)
- `email_address`: Subscriber email (required)
- `status`: "subscribed", "pending", "unsubscribed", "cleaned", "transactional" (required)

**Pitfalls**:
- `subscriber_hash` must be MD5 of the **lowercase** email; incorrect casing causes 404s or duplicates
- Use `MAILCHIMP_ADD_OR_UPDATE_LIST_MEMBER` (upsert) instead of `MAILCHIMP_ADD_MEMBER_TO_LIST` to avoid duplicate errors
- `status_if_new` determines status only for new contacts; existing contacts use `status`
- Use `skip_merge_validation: true` to bypass required merge field validation
- `MAILCHIMP_BATCH_ADD_OR_REMOVE_MEMBERS` manages static segment membership, not list membership

### 4. View Campaign Reports and Analytics

**When to use**: User wants to review campaign performance, open rates, click rates, or subscriber engagement.

**Tool sequence**:
1. `MAILCHIMP_LIST_CAMPAIGNS` - List sent campaigns with report summaries [Required]
2. `MAILCHIMP_SEARCH_CAMPAIGNS` - Find campaigns by name, subject, or content [Optional]
3. `MAILCHIMP_GET_CAMPAIGN_REPORT` - Get detailed performance report for a campaign [Required]
4. `MAILCHIMP_LIST_CAMPAIGN_REPORTS` - Bulk fetch reports across multiple campaigns [Optional]
5. `MAILCHIMP_LIST_CAMPAIGN_DETAILS` - Get link-level click statistics [Optional]
6. `MAILCHIMP_GET_CAMPAIGN_LINK_DETAILS` - Drill into specific link click data [Optional]
7. `MAILCHIMP_LIST_CLICKED_LINK_SUBSCRIBERS` - See who clicked a specific link [Optional]
8. `MAILCHIMP_GET_SUBSCRIBER_EMAIL_ACTIVITY` - Get per-subscriber campaign activity [Optional]
9. `MAILCHIMP_GET_CAMPAIGN_CONTENT` - Retrieve campaign HTML content [Optional]

**Key parameters for MAILCHIMP_LIST_CAMPAIGNS**:
- `status`: "save", "paused", "schedule", "sending", "sent"
- `count` / `offset`: Pagination (default 10, max 1000)
- `since_send_time` / `before_send_time`: ISO 8601 date range filter
- `sort_field`: "create_time" or "send_time"
- `fields`: Limit response fields for performance

**Key parameters for MAILCHIMP_GET_CAMPAIGN_REPORT**:
- `campaign_id`: Campaign ID (required)
- Returns: opens, clicks, bounces, unsubscribes, timeseries, industry_stats

**Pitfalls**:
- `MAILCHIMP_LIST_CAMPAIGNS` only returns high-level `report_summary`; use `MAILCHIMP_GET_CAMPAIGN_REPORT` for detailed metrics
- Draft/unsent campaigns lack meaningful report data
- When using `fields` parameter on LIST_CAMPAIGNS, explicitly request `send_time` and `report_summary` subfields
- Pagination defaults are low (10 records); iterate with `count` and `offset` until `total_items` is covered
- `send_time` is ISO 8601 with timezone; parse carefully

#### Imported: 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

## Examples

### Example 1: Ask for the upstream workflow directly

```text
Use @mailchimp-automation to handle <task>. Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer.
```

**Explanation:** This is the safest starting point when the operator needs the imported workflow, but not the entire repository.

### Example 2: Ask for a provenance-grounded review

```text
Review @mailchimp-automation against metadata.json and ORIGIN.md, then explain which copied upstream files you would load first and why.
```

**Explanation:** Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection.

### Example 3: Narrow the copied support files before execution

```text
Use @mailchimp-automation for <task>. Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding.
```

**Explanation:** This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default.

### Example 4: Build a reviewer packet

```text
Review @mailchimp-automation using the copied upstream files plus provenance, then summarize any gaps before merge.
```

**Explanation:** This is useful when the PR is waiting for human review and you want a repeatable audit packet.



## Best Practices

Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution.

- Keep the imported skill grounded in the upstream repository; do not invent steps that the source material cannot support.
- Prefer the smallest useful set of support files so the workflow stays auditable and fast to review.
- Keep provenance, source commit, and imported file paths visible in notes and PR descriptions.
- Point directly at the copied upstream files that justify the workflow instead of relying on generic review boilerplate.
- Treat generated examples as scaffolding; adapt them to the concrete task before execution.
- Route to a stronger native skill when architecture, debugging, design, or security concerns become dominant.



## Troubleshooting

### Problem: The operator skipped the imported context and answered too generically

**Symptoms:** The result ignores the upstream workflow in `plugins/antigravity-awesome-skills-claude/skills/mailchimp-automation`, fails to mention provenance, or does not use any copied source files at all.
**Solution:** Re-open `metadata.json`, `ORIGIN.md`, and the most relevant copied upstream files. Check the `external_source` block first, then restate the provenance before continuing.

### Problem: The imported workflow feels incomplete during review

**Symptoms:** Reviewers can see the generated `SKILL.md`, but they cannot quickly tell which references, examples, or scripts matter for the current task.
**Solution:** Point at the exact copied references, examples, scripts, or assets that justify the path you took. If the gap is still real, record it in the PR instead of hiding it.

### Problem: The task drifted into a different specialization

**Symptoms:** The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better.
**Solution:** Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind.

#### Imported: Common Patterns

### ID Resolution
Always resolve names to IDs before operations:
- **Audience name -> list_id**: `MAILCHIMP_GET_LISTS_INFO` and match by name
- **Subscriber email -> subscriber_hash**: Compute MD5 of lowercase email in code
- **Campaign name -> campaign_id**: `MAILCHIMP_SEARCH_CAMPAIGNS` with query
- **Segment name -> segment_id**: `MAILCHIMP_LIST_SEGMENTS` with list_id

### Pagination
Mailchimp uses offset-based pagination:
- Use `count` (page size, max 1000) and `offset` (skip N records)
- Continue until collected records match `total_items` from the response
- Default `count` is 10; always set explicitly for bulk operations
- Search endpoints max at 10 pages (300 results for 30/page)

### Subscriber Hash
Many endpoints require `subscriber_hash` (MD5 of lowercase email):
```
import hashlib
subscriber_hash = hashlib.md5(email.lower().encode()).hexdigest()
```

#### Imported: Known Pitfalls

### ID Formats
- `list_id` (audience ID) is a short alphanumeric string (e.g., "abc123def4")
- `campaign_id` is an alphanumeric string
- `subscriber_hash` is an MD5 hex string (32 characters)
- Segment IDs are integers

### Rate Limits
- Mailchimp enforces API rate limits; use batching for bulk subscriber operations
- High-volume use of GET_MEMBER_INFO and ADD_OR_UPDATE_LIST_MEMBER can trigger throttling
- Use `MAILCHIMP_BATCH_ADD_OR_REMOVE_MEMBERS` for bulk segment operations

### Parameter Quirks
- Nested parameters use double-underscore notation: `settings__subject__line`, `recipients__list__id`
- `avg_open_rate` and `avg_click_rate` are 0-1 fractions, not percentages
- `status_if_new` only applies to new contacts in upsert operations
- `subscriber_hash` must be MD5 of lowercase email; wrong casing creates phantom records
- Campaign `type` is required for creation; most common is "regular"
- `MAILCHIMP_SEND_CAMPAIGN` returns HTTP 204 on success (no body)

### Content and Compliance
- Campaign HTML must include unsubscribe link and physical address (merge tags)
- Content must be set via `MAILCHIMP_SET_CAMPAIGN_CONTENT` before sending
- Test emails require campaign to have content already set

#### Imported: Limitations

- Use this skill only when the task clearly matches the scope described above.
- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
