Mailchimp

To connect your Mailchimp account and add users to your email lists, navigate to Settings, click on Applications, and choose Mailchimp. If needed, you can add multiple applications.

Next, you'll need to add your Mailchimp API key. If you don't know your API key, you can find it by following the link to the Mailchimp API documentation.

After connecting your email service, a new button showing the name of your email service provider will appear on your forms and checkout widgets.

Using this button, you can add your visitors to your chosen email lists, including multiple lists if needed.
