In version 1.7 we integrated MailChimp to Subscribe form, so subscribed users will be automatically added to MailChimp list, that makes easiest possibilities to manage subscribers for admin: subscriber's contacts storage, letter sending and other control actions.

In order to use a Mailchimp form for Subscribe block, you need to do the following steps:
1. Please, create a form.
-You are able to create your custom form

-If you want to create the "inline subscriber's form" inside the MailChimp (one of available Utouch form):

Then, use the following code and insert it into "Form code" area:
<div class="form-inline"> <input type="email" name="EMAIL" placeholder="Your email address" /> <button type="submit" class="btn btn--primary subscr-btn es_submit_button">Subscribe</button> </div>
-In a case of standard subscribe form, please use this code:
<input type="text" name="FNAME" placeholder="First Name">
<input type="text" name="LNAME" placeholder="Last Name">
<input type="email" name="EMAIL" placeholder="Your email address" />
<button type="submit" class="btn btn--primary btn--with-shadow full-width subscr-btn">Subscribe</button>

2. Copy a shortcode of created form.

3. Insert a shortcode into “Custom shortcode” field in "Subscribe form Settings"

As seen, the created MailChimp form can be easily applied to Subscribe block.
