Just a quick FAQ for those that get the following error message while using the MailChimp Module.

Can't find lists: Invalid Mailchimp API Key: xxxxxxxxxxxxx . You are accessing the wrong datacenter - your client library may not properly support our datacenter mapping scheme.
Error code: 104


Please make sure you're using the entire API key.  The MailChimp API looks for the Datacenter ID at the end of your API key:


If you just use the numeric portion, MailChimp won't recognize your datacenter.

(Developer's note:  I'm so used to double-clicking to select a whole word that I've goofed this up myself!  Just don't tell anyone.)

Keeping in touch with our email list subscribers is critical, but we don't often have time to construct a new campaign and send it. MailChimp's RSS-to-Email campaigns allow you to make updates in one place--your web site--and automatically notify members of your participating list of the updates. It is an easy way to communicate if you're already blogging or writing! In this tutorial, we will show you how to set up MailChimp so it periodically looks for new content on your site and email it to your list subscribers.

When configuring your MailChimp module, you will be asked for a MailChimp API key and list ID. Both of these are located in your MailChimp account, and are accessible after logging in at www.MailChimp.com. Here's how you find them...

API Key:
From the top, right menu, select Account, Extras, API Keys & Authorized Apps. Your API Key will be listed in the table labeled "Your API Keys". Best to copy and paste into the MailChimp Module setup.

List ID:
When viewing your MailChimp Lists, select the list you wish to offer user sign-up, then click the word "Settings". Your list id will be in the bottom field of the resulting page. Best to copy and paste into the MailChimp Module setup. If you enter an invalid id, the module will default to the first list.

The original version of the 3by400 MailChimp Module2 used MailChimp's previous API. The latest version of our MailChimp module uses the current version of the MailChimp API. Please register for the updates mailing list.  You will then be able to download and install the newest version.

Yes, the latest version of 3by400's MailChimp Module2 does work with Joomla 1.5 and 2.5. The module is free, but registration for our mailing list is required to download the module. Once you complete the mailing list registration, you will be re-directed to the download page.
