We discovered the insanely great e-mail subscription service MailChimp. Located in Atlanta, they seem light-years ahead of the other e-mail marketing programs we've used. Only problem is that to allow sign-up from a Joomla site, it was necessary to use MailChimp's "insert your HTML here". To simplify your site visitor's ability to sign up for your eBlasts, we created MailChimp Module2. This module allows you to display your MailChimp subscription form natively on your Joomla site. All other MailChimp configuration is performed within your account at MailChimp.com.

Mailchimp recently changed the way 3rd parties integrate with their service (their API). This required a rewrite of the internals of the module which is now available. If you are currently using a previous release of our module, please download the new version.

From the admin site, provide your MailChimp user name and password, and the mailing list id of the list you want the user to subscribe to. From the front side, the user types in his or her email address and clicks the submit button. The module does an AJAX call to the subscription program, so there is no page refresh. We proudly offer you our Joomla MailChimp Module2:
