Mailchimp drupal 7 success message

Hi I've successfully implemented the mailchimp form and the entries are being posted to my mailchimp list.开发者_JS百科

However I'm not able to output a success message to the user. How do I go about doing this?

The drupal_set_message function allows you to output status, warning, and error messages to a page.

Though there's not an official release of the Mailchimp module, you may want to look into using it, instead of developing your own Mailchimp integration module.
