You can use Zapier to connect your Stripe account with Mailchimp, allowing you to automatically add new customer email addresses to your Mailchimp audience every time a new customer is created in Stripe. Before setting up the integration, ensure that your Mailchimp account is set up to receive information from Stripe and create an automated workflow called a Zap using Zapier's template or by creating one from scratch without coding knowledge. In the setup process, you'll need to connect your Stripe account with a general set of permissions, select the New Customer trigger event, test the trigger with sample data, sign in to your Mailchimp account, and customize the new subscriber fields before testing the Zap. Once everything is set up correctly, every new Stripe customer will be added to your selected Mailchimp Audience.
