GetResponse integration works only for specific forms

Hi guys,

I have two Contact forms integrated with GetResponse using the official GetResponse plugin and Contact Form 7.
The issue that arises is that with the below ‘default’ form formatting, the integration works fine and the contact is added to the GetResponse contact list:

<label>Name</label>
    [text* your-name]

<label>Email address</label>
    [email* email] 

[acceptance signup-to-newsletter id:signup-to-newsletter class:signup-to-newsletter]Subscribe to our newsletter![/acceptance]

[submit "Submit"]

But the below contact form, which has a more custom layout (although almost same input fields), doesn’t work and the contact is not added to the list:

<div class="homepage-form-wpcf-wrap">
  <div class="homepage-form-two-third">
    <div class="homepage-form-one-half">
      [text* your-name placeholder "Name"]
    </div>

    <div class="homepage-form-one-half homepage-form-last">
      [email* email placeholder "E-mail"]
    </div>

    <div class="homepage-form-wpcf-accept">
      [acceptance signup-to-newsletter-home id:signup-to-newsletter-home class:signup-to-newsletter-home default:on optional]Subscribe to our newsletter![/acceptance]
    </div>
  </div>

  <div class="homepage-form-one-third homepage-form-last">
   [submit "JOIN"]
  </div>
</div>

Any idea what could be causing the issue?
