title: MailChimp - Sending the welcome email instantly
body: <p>Normally once a user signs up to my website the "welcome" email is delivered to the subscriber after one hour (default from the MailChimp).</p>
  
  <p>How can I instantly send this welcome email to a user once they complete the signup form on my site.</p>
  
  <p>Is there any way I can do this through the MailChimp API or some custom coding?</p>
