The Webform Mailchimp module allows you to send Webform submissions to your Mailchimp list whilst also allowing you to map the Drupal webform fields to MailChimp form fields.

When a user submits the Drupal webform, the submission details are sent directly to MailChimp. When you log into MailChimp you can view the submission details within the MailChimp interface and the fields are mapped accordingly.

This can be easily accomplished using the Webform Mailchimp module (along with its dependencies). The dependencies are:

• Webform module
• MailChimp module
• MailChimp API PHP library (MailChimp module dependency)

You need a MailChimp account (with at least one list).
