Hey @binomi
Thanks for your post. I’m afraid that the List Subscribe plugin can only connect to a single list in the MailChimp account. Due to this limitation, it’s only possible to subscribe users to a single list in your MailChimp account. That said, I can certainly pass this feedback along to our team for consideration in the future.
In the meantime, I might suggest investigating a separate signup form plugin that would allow you to connect an additional signup form to your additional list.
If you do have any questions, please let us know.
Thanks,
Malachite
