Mailchimp review
Assistive AI in a known UI. The harness mostly cannot drive it.
TL;DR. Mailchimp is the known UI. Brew plus export or migrate when the harness needs a canvas. Brew vs Mailchimp.

What the agent cannot see
Mailchimp thinks in campaigns a human clicks. Assistive copy is not tool discovery. If the harness cannot call it, we do not count it as agent-ready.
Ease of use scores high because humans already know the UI. Agent cognition scores low.
Automation limits
Journeys help. They lag Customer.io and Klaviyo on events. Outgrow and add Brew.
Pricing
Free for small lists. Paid by contacts. See mailchimp.com/pricing.
Verdict
Keep Mailchimp if the office already lives there. Wire Brew when the harness must operate email.
