title: Devise skip confirmation notification before save
body: <p>In Rails 4.2.0, I am using the Devise gem for authentication - <code>devise 3.4.1</code>.</p>
  
  <p>The confirmation email is sent as soon as a user is created. We need to skip this confirmation email and send a custom email with the confirmation link. Please help me to solve this issue.</p>
