Simple MailChimp

The intention of this module is to give site builders an easy way to add a subscription option at the end of existing forms so that users can be added to your MailChimp list from any form on the site.

An example scenario is that you have a warranty, contact, or some other form on your site already, and you would like to give users the option to subscribe to your MailChimp list on those forms. Whether it's built using the webform module, custom module or something else, all you need is a form ID and the name of your email field to configure.

It is not meant in any way to be as robust as the standard https://www.drupal.org/project/mailchimp. You can't manage subscribers. You can't work with lists. It simply gives you the ability to add a checkbox for subscribing to a MailChimp list, and also allows a field for one interest group option.

To configure, you will need your MailChimp API key, list ID, and a mapping of fields. See images.
