title: Is there a way where my users could be subscribed to a list without a confirmation mail?
body: <p>I have integrated <strong>Hype mailchimp</strong> with <strong>Symfony2</strong>,
  When a user subscribes to my website, he/she gets a confirmation mail from mailchimp which asks if they want to subscribe to a particular list or not.</p>
  
  <p>Is there a setting in mailchimp or a switch/config setting in the bundle from which I could switch off this confirmation mail and my users could directly be added to the list.</p>
  
  <p>Thanks in advance!</p>
