What is it?
This script is an interface between the form on your page and the MailChimp API.
Data from your form is submitted to this script, which is then processed and sent on to MailChimp.
We've taken the hard work out of setting up the API integration. By configuring the settings in the
forms/mailchimp.php file you can easily add subscribers to your lists in MailChimp through the forms on your website.
Subscribers will be added to your MailChimp account, on a list you specify. MailChimp handles double opt-in and provides feedback when the user has already subscribed.
You may then do what you wish with the list of subscribers such as send email through MailChimp, or export them to use on another service.
