How to use Mailchimp Campaign Management MCP server tools ​

Refer to the following sections for detailed information on available tools:

list_audiences tool ​

The list_audiences tool lists the audiences (lists) in the Mailchimp account. Your LLM uses this tool to return audiences with their identifiers, names, and member counts so it can choose the right audience to add contacts to or target with a campaign, typically before adding contacts or drafting a campaign when the target audience is not yet resolved.

Try asking:

• Show me all the audiences in my Mailchimp account.
• Which lists do I have and how many contacts are in each?
• Find the audience I should add these contacts to.

list_campaigns tool ​

The list_campaigns tool lists campaigns in the account, with optional status filtering. Your LLM uses this tool to return campaigns with their identifiers, titles, subjects, status, and target audience so it can find a draft to send or schedule, filtering by status when you specify drafts, scheduled, or sent campaigns.

Try asking:

• List my draft campaigns.
• Which campaigns are scheduled to send?
• Show me all my sent campaigns.

get_campaign tool ​

The get_campaign tool retrieves a single campaign's settings and content. Your LLM uses this tool to confirm a campaign's subject, sender, recipient audience, status, and current content before updating, sending, or scheduling it.

Try asking:

• Show me the details of my launch campaign.
• What's the current subject and sender on this campaign?
• Confirm the recipient audience for this draft before I send it.

search_contacts tool ​

The search_contacts tool searches for contacts by email or name, with optional filtering by an audience. Your LLM uses this tool to resolve a contact's identifier before updating or tagging it, scoping the search to a single audience when you name one or spanning the account otherwise.

Try asking:

• Find the contact for [email protected].
• Search for contacts named Smith in my newsletter audience.
• Look up whether this person is already in my launch list.

create_audience tool ​

The create_audience tool creates a new audience (list) in the account. Your LLM uses this tool when you want to stand up a fresh audience for a campaign, using the name and the required audience settings you supply, such as default campaign settings, a permission reminder, the email-type option, and the physical contact details Mailchimp requires. If this tool fails, check whether your Mailchimp plan has reached its audience limit.

Try asking:

• Create a new audience called "Fall Launch".
• Set up a fresh list for our newsletter subscribers.
• Make a new audience with these default sender details.

add_contact tool ​

The add_contact tool adds a contact to an audience with a subscription status. Your LLM uses this tool when you want to add a person to an audience. You can specify whether to set a member to subscribed, which immediately adds and asserts pre-existing consent, or send them a double opt-in confirmation email.

Try asking:

• Add [email protected] to my newsletter audience as subscribed.
• Add these contacts to my launch list and send them a confirmation.
• Add this person with their first and last name to my audience.

update_contact tool ​

The update_contact tool updates an existing contact's fields within an audience. Your LLM uses this tool to change a contact's profile fields or subscription status, resolving the contact first when its identifier is unknown and leaving other fields unchanged.

Try asking:

• Update the first name on this contact to "Jordan".
• Change the profile fields for [email protected] in my newsletter list.
• Fix the last name on this contact record.

tag_contact tool ​

The tag_contact tool applies or updates tags on a contact within an audience. Your LLM uses this tool to label or group a contact for targeting, adding or removing one or more tags and resolving the contact first when its identifier is unknown.

Try asking:

• Tag [email protected] as VIP.
• Add the "early access" tag to these contacts.
• Remove the "prospect" tag from this contact.

draft_campaign tool ​

The draft_campaign tool creates a campaign draft from supplied content and settings. Your LLM uses this tool to turn ready content into a Mailchimp campaign, assembling a draft against the chosen audience with the subject and sender you provide and attaching the supplied HTML or plain-text content. The server doesn't generate, design, or modify the content. Subject lines longer than approximately 150 characters are truncated by Mailchimp.

Try asking:

• Draft a campaign to my newsletter audience using this HTML.
• Turn this content into a Mailchimp campaign with the subject "Summer Sale".
• Create a draft campaign from this plain-text email for my launch list.

update_campaign tool ​

The update_campaign tool updates a campaign's subject, sender, or recipient audience. Your LLM uses this tool to change a campaign's settings before sending or scheduling, leaving other settings unchanged. It doesn't change body content or send and schedule the campaign.

Try asking:

• Change the subject line on this campaign to "Summer Sale is here".
• Update the sender name on my draft campaign.
• Switch the recipient audience for this campaign to my VIP list.

send_test tool ​

The send_test tool sends a test email of a campaign to specified addresses. Your LLM uses this tool to let you preview a campaign safely before the real send by emailing a test to yourself or colleagues, without sending to the campaign's audience. The campaign must have HTML content; a plain-text-only draft can't be tested.

Try asking:

• Send a test of this campaign to me.
• Email a preview of my launch campaign to my teammate.
• Send a test of this campaign to these addresses.

send_campaign tool ​

The send_campaign tool sends a campaign immediately. Once sent, a campaign cannot be recalled. The server requires explicit user confirmation that you want to send the campaign now before using this tool.

Try asking:

• Send my newsletter campaign now.
• Yes, send the launch campaign to my audience.
• Confirm and send this campaign immediately.

schedule_campaign tool ​

The schedule_campaign tool schedules a campaign to send at a future time. Your LLM uses this tool when you want a campaign to go out at a specific time in the future, after confirming the campaign's settings. Scheduling remains reversible until the send begins. The campaign must have HTML content to be scheduled.

Try asking:

• Schedule this campaign to send Tuesday at 9am.
• Set my launch campaign to go out next Monday morning.
• Schedule this campaign for tomorrow at noon.

unschedule_campaign tool ​

The unschedule_campaign tool cancels the schedule of a campaign that has not started sending. Your LLM uses this tool to cancel or change a scheduled send before it goes out, returning the campaign to a paused state. It has no effect once a send has started.

Try asking:

• Unschedule the campaign I set for tomorrow morning.
• Cancel the scheduled send on my launch campaign.
• Stop this campaign from sending on Tuesday.
