How to connect Mailchimp and Slack

Create a new workflow and add the first step

In n8n, click the "Add workflow" button in the Workflows tab to create a new workflow. Add the starting point – a trigger on when your workflow should run: an app event, a schedule, a webhook call, another workflow, an AI chat, or a manual trigger. Sometimes, the HTTP Request node might already serve as your starting point.

Mailchimp and Slack integration: Create a new workflow and add the first step

Send daily Mailchimp subscriber reports to Slack

What this workflow does This workflow sends a daily Slack report with the current number of subscribers in your Mailchimp list. It’s a simple way to keep your marketing or growth team informed without logging into Mailchimp. How it works Cron Trigger starts the workflow once per day (default: 09:00). Mailchimp node retrieves the total number of subscribers for a specific list. Slack node posts a formatted message with the subscriber count into your chosen Slack channel. Pre-conditions / Requirements A Mailchimp account with API access enabled. At least one Mailchimp audience list created (you’ll need the List ID). A Slack workspace with permission to post to your chosen channel. n8n connected to both Mailchimp and Slack via credentials. Setup Cron Trigger Default is set to 09:00 AM daily. Adjust the time or frequency as needed. Mailchimp: Get Subscribers Connect your Mailchimp account in n8n credentials. Replace {{MAILCHIMP_LIST_ID}} with the List ID of the audience you want to monitor. To find the List ID: Log into Mailchimp → Audience → All contacts → Settings → Audience name and defaults. Slack: Send Summary Connect your Slack account in n8n credentials. Replace {{SLACK_CHANNEL}} with the name of the channel where the summary should appear (e.g., #marketing). The message template can be customized, e.g., include emojis, or additional Mailchimp stats. Customization Options Multiple lists: Duplicate the Mailchimp node for different audience lists and send combined stats. Formatting: Add more details like new subscribers in the last 24h by comparing with previous runs (using Google Sheets or a database). Notifications: Instead of Slack, send the update to email or Microsoft Teams by swapping the output node. Benefits Automation: Removes the need for manual Mailchimp checks. Visibility: Keeps the whole team updated on subscriber growth in real time. Motivation: Celebrate growth milestones directly in team channels. Use Cases Daily subscriber growth tracking for newsletters. Sharing metrics with leadership without giving Mailchimp access. Monitoring the effectiveness of campaigns in near real time.
