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

1. Cron Trigger starts the workflow once per day (default: 09:00).
2. Mailchimp node retrieves the total number of subscribers for a specific list.
3. 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

1. Cron Trigger

   • Default is set to 09:00 AM daily. Adjust the time or frequency as needed.

2. 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.

3. 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.
