In this article, you'll learn how to connect or disconnect Mailchimp for BigCommerce.

Before you start

Here are some things to know before you begin this process.

• Mailchimp for BigCommerce adds your e-commerce customers and their purchase data to your Mailchimp audience.
• Pop-up forms, product retargeting emails, and abandoned cart emails require the latest version of Mailchimp for BigCommerce.
• If you create an order notifications automation, you'll need to disable your corresponding notifications in BigCommerce to avoid sending duplicate emails to your customers.
• To disable the "I'd like to receive your newsletter" checkbox that appears at the bottom of your store checkout page, go to the Newsletter Settings section of your BigCommerce dashboard.
• To view the e-commerce features supported by this integration, visit the BigCommerce listing in your account.
• This integration is compatible with our Marketing API version 3.0.

How it works

Mailchimp for BigCommerce syncs your customer data to your Mailchimp audience. Customers who sign up to your newsletter will be added as subscribed contacts, eligible to receive any type of marketing. Customers who choose not to receive marketing emails will appear as non-subscribed contacts. Learn more about [contact types|(/help/about-your-contacts/)

Their order information will also appear in the activity feed on their contact profile. Use order information to send targeted campaigns and sell more stuff.

Mailchimp for BigCommerce syncs contacts one-way, meaning updates to a contact in Mailchimp will not affect their BigCommerce profile. Non-subscribed customers who opt-in to receive marketing emails get updated to subscribed in Mailchimp. Mailchimp for BigCommerce cannot unsubscribe contacts.

To fully install the integration, you'll need to connect your store to Mailchimp, select the audience you want to sync with, and choose your sync settings. Depending on your theme, you may also need to install scripts to enable Mailchimp e-commerce features.

[!NOTE] In order to honor all subscription newsletter opt-in settings during customer checkouts, you'll need disable guest checkout entirely. For more information, refer to the BigCommerce article Guest Customers and Checkout.

Turn on Site Tracking

Mailchimp for BigCommerce includes the Mailchimp Site Tracking Pixel, which captures what visitors do on your store, like page views, product views, add to cart, checkout, search, and purchases. Use this data to build segments and trigger automation flows. The pixel is separate from the Blueprint theme script described above; you don't need to add any code to your store.

Site Tracking is off by default when you connect. To turn it on, in Mailchimp select Integrations, then Manage, select BigCommerce, select Settings, and scroll to Site tracking.

If your store connected to Mailchimp before June 2026, BigCommerce blocks tracking until you re-authorize the Mailchimp app so it gets the updated permissions. Open the Mailchimp app in your BigCommerce control panel and accept the new permissions, then turn Site Tracking on.
