Mailchimp is where millions of small businesses run their email marketing, and the Mailchimp API is one of the better-documented marketing APIs out there. OpenClaw makes it easy to monitor your account, get smart reports, and draft better emails faster.

Connecting to Mailchimp

You need a Mailchimp API key (found in Account > Extras > API Keys):

openclaw config set integrations.mailchimp.apiKey YOUR_API_KEY_HERE
openclaw config set integrations.mailchimp.serverPrefix us21
# Server prefix comes from your API key — the part after the dash

Campaign Performance Reports

openclaw cron add "0 8 * * MON" "mailchimp-weekly-report" \
  --task "Fetch all Mailchimp campaigns sent in the last 7 days.
         For each campaign: open rate, click rate, bounce rate, unsubscribes.
         Compare to list average rates. Flag underperformers.
         Post weekly digest to #email-ops Slack."

Audience Growth Tracking

openclaw cron add "0 8 * * MON" "mailchimp-list-growth" \
  --task "Fetch subscriber counts for each Mailchimp audience.
         Compare to 4 weeks ago. Calculate weekly growth rate.
         Flag any audience shrinking (unsubscribes > new subscribers).
         Post to #email-ops."

Subject Line Testing Analysis

If you run A/B tests in Mailchimp, export the results as CSV and have the agent analyze patterns: which types of subject lines perform best by length, format (questions vs statements), emoji usage, and emotional trigger (urgency vs curiosity). Your own data, properly analyzed, beats any generic best-practice advice.

Email Content Drafting

For newsletters or promotional campaigns, provide a brief with issue name, audience, key content, tone, and length target. The agent drafts a compelling subject line, preview text, section headers, and email body. You edit and import into Mailchimp's editor.

Automation Monitoring

Mailchimp automations can silently stop working due to authentication issues or trigger problems. Set up a weekly audit that checks all your active automations are sending and performing within expected ranges.

Tag Management

Monthly audit of tag usage, merging near-duplicate tags, and flagging subscribers with conflicting tags that could cause them to receive wrong campaigns. Clean tags mean clean segmentation.

The OpenClaw Playbook covers the Mailchimp integration fully — API setup, reporting automation, and content drafting workflows for lists of all sizes. It's $9.99 at openclawplaybook.ai.

Frequently Asked Questions

What Mailchimp features can OpenClaw access via API?

OpenClaw can access Mailchimp's full Marketing API: campaigns, reports, audiences, tags, segments, automations, and landing pages. This covers essentially everything in your Mailchimp account.

Can OpenClaw send emails through Mailchimp?

Yes, with appropriate caution. OpenClaw can create and schedule campaigns via the Mailchimp API. We recommend a human review step before any campaign actually sends — use the agent to draft and schedule to draft, then you approve.

Does OpenClaw work with Mailchimp's free plan?

The Mailchimp API is available on all plans including free. API call limits are generous — you'd have to be running very high-frequency polling to hit them on a typical small business account.
