Reorder Signup Block Fields

Unfortunately, the MailChimp dashboard doesn't give you a way to move the email address on the MailChimp side. So, there are a few options. Starting with the fastest to the most complex:

1. Move it with jquery.
2. Write a hook_form_alter to reorder the fields.
3. Create a form using Drupal fields and the mailchimp field instead of using the signup block. This might require something like Entity Form.
4. Write a patch for MailChimp module to allow the fields to be reordered in the admin UI for signup block.

I've never tried to use a Twig template to build a drupal form. But, I believe it should work. My coworker's talk from DrupalCon will help you figure out how to do this:

Yea, I'm not really sure how to use Twig for a Drupal form. So, JS for the win. :)

I developed a patch implementing this feature as well as additional other customization. Please see #3390459: Customize display of signup fields.
