Minimal Mailchimp Signup Form

I need a clean, no-frills subscriber form added to my WordPress site’s homepage. The form must collect an email address plus the visitor’s first and last name, and push all three fields straight into my existing Mailchimp list without fail.

The look should remain simple and minimalistic so it blends seamlessly with the current theme—no extra colours or graphics, just crisp spacing and typography consistent with the site’s styling.

Please handle the full setup: connect the form to Mailchimp, embed it on the homepage (block, shortcode, or template edit—whatever suits), and verify that a test subscription lands in the correct list with all fields populated.

Deliverable is a fully functioning, styled form live on the homepage with Mailchimp integration confirmed.
