Mailchimp

List all Mailchimp accounts connected for the authenticated user. Returns account IDs, names, data centers, and login emails.

List all audiences (lists) in the Mailchimp account with name search and pagination. Returns member count, open rate, click rate, and list rating for each audience.

Get detailed information about a specific Mailchimp audience (list), including stats, settings, and campaign defaults.

Troubleshoot authentication issues and get user profile info. Only use when another tool fails with a permission or authentication error — do NOT call proactively.

List automations (classic automations / customer journeys) in the Mailchimp account with status filtering, title search, and pagination.

Get detailed information about a specific Mailchimp automation including all associated emails with their delivery stats.

List campaigns in the Mailchimp account with status filtering, server-side title search, sorting, date range filtering, and pagination. When the search parameter is provided (without a cursor), routes to Mailchimp's /search-campaigns endpoint for accurate server-side matching sorted by most recent send_time — ideal for campaign disambiguation by title. Results include web_id, audience name, and send_time for easy identification. Use sort_field=send_time with sort_dir=DESC to get the most recently sent campaigns first. Use since_send_time/before_send_time to filter by send date window.

Get detailed information about a specific Mailchimp campaign. Optionally includes content preview (text/HTML, truncated) and send checklist.

Health check for the Mailchimp MCP server. Does not call the Mailchimp API.

Get all stored preferences for a Mailchimp entity. Preferences are also automatically attached to entity-listing responses, so you often don't need to call this explicitly.

Get a detailed performance report for a sent Mailchimp campaign, including opens, clicks, bounces, forwards, ecommerce, delivery status, and industry comparison stats.

Get insights for a Mailchimp audience including growth history, activity, email clients, and geographic locations. Each data source is fetched in parallel and degrades gracefully on failure.

Get email activity (opens, clicks, bounces) for individual recipients of a sent Mailchimp campaign. Supports pagination.

Get per-variant performance data for an A/B split or multivariate campaign test. Returns variant-level metrics including opens, clicks, bounces, ecommerce, and winner status. Each variant includes a test_type field (subject_line, from_name, content, send_time, multivariate, unknown) and a changed_dimensions object with structured variant definition data (subject_line, from_name, reply_to, content_label, send_time_variant). Ecommerce data includes currency and an ecommerce_data_complete flag indicating whether all variants have data. Works for both A/B split (2 variants) and multivariate (multiple combinations) campaigns. Use mailchimp_list_campaigns with type filter ["absplit", "variate"] to find testable campaigns.

List segments for a Mailchimp audience with optional type filtering and pagination. Segment types include saved, static, and fuzzy.

List subscribers (members) of a Mailchimp audience with status filtering, email search, and pagination. Requires an audience_id. Use search to find specific subscribers by email or name.

Get detailed information about a specific subscriber by email address or MD5 hash. Optionally includes recent activity feed.

List tags for a Mailchimp audience with pagination. Tags are user-defined labels applied to subscribers for organization and segmentation.

List email templates in the Mailchimp account with type filtering, name search, and pagination. Filter by type (user, base, gallery) to narrow results.
