Mailchimp & Bold Brain Integration

Bold Brain is integrated with Mailchimp to allow you to send emails to certain groups of customers.

This integration uses Brain's Audiences feature to help segment these different groups of customers. You can then use these audiences to email your customers about specific promotions, products, or deals.


Mailchimp requires you to create an account in order to use this integration. Visit the Mailchimp signup page to create a free account.


Bold Brain is no longer available for new installations. If you currently have Bold Brain installed on your store, it will continue to function as expected.
