Big Cartel integrated Mailchimp's email marketing tools into its paid plans, giving sellers access to over 100 email templates powered by generative AI and customer purchase data. The AI capability belongs to Mailchimp, not Big Cartel, but Big Cartel surfaces it through its official integration and help documentation.

Big Cartel's official help page for its Mailchimp integration states that sellers who connect their store to Mailchimp gain access to over 100 email templates powered by generative AI and customer data. The generative AI is Mailchimp's own technology, branded as Intuit Assist and Write with AI, not built by Big Cartel. Mailchimp's generative AI writing features are available only to accounts with a primary mailing address in Australia, Canada, the United Kingdom, or the United States, and require a Mailchimp Standard plan or higher. The integration also enables personalized product recommendations and post-purchase follow-up automations based on customer purchase history. The basic Mailchimp integration is free for all Big Cartel sellers, including those on the free Gold plan, though some premium integration features require a paid Big Cartel plan.
