Using the Extension
The extension will add a Mailchimp tab to the WP-Members admin panel.
You will need your Mailchimp API key and an audience ID. You’ll also need to indicate which checkbox field is being used to subscribe a user. A dropdown list will list all checkbox fields in your registration form (except for the TOS field). From this list, choose the checkbox that is intended for Mailchimp subscription opt-in. If no checkbox fields exist, it will tell you to create one. This can be done in the fields tab.
