MailChimp Subscribe
Automatically add new members to MailChimp mailing lists.
Usage Instructions
Once the extension is installed and configured, it will automatically subscribe newly registered users to the specified MailChimp mailing lists.
If you’ve specified “Self-activation via email” in your ExpressionEngine Membership Preferences (EE1 docs / EE2 docs), mailing list subscriptions will not be processed until the member has confirmed his registration.
The extension works best with “single opt-in” MailChimp lists.
