Received e-mail: "Your MailChimp account is using the login() API method which will be disabled in the near future."

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.
