Subscription Rules and Settings

In order to configure the MailChimp integration subscription rules and settings, you must first create lists in MailChimp for your customers to be added to. For instructions on how to do this, see MailChimp's documentation.

Once you have set up mailing lists in MailChimp, you can use subscription rules in BigCommerce to determine which lists your customers are added to.


When someone subscribes on your storefront, you can choose to Add or Remove them from any of your MailChimp lists.

The Newsletter Subscription Rules settings.

Click the green plus (+) to add a new rule, the red minus (-) to delete a rule, and the paper icon to copy a rule.


When someone orders:

  • anything in your store
  • from this category (choose a category)
  • from this brand (choose a brand)
  • this specific product (choose the product)

You can either add or remove them from any of your lists in MailChimp.

The Add or Remove from list drop-down.

Click the green plus (+) to add a new rule, the red minus (-) to delete a rule, and the paper icon to copy a rule.

Syncing order fields will allow MailChimp to match certain information provided by the customer to particular contact fields in MailChimp.
