title: Magento auto email send to user after place order
body: <p>I am working on magento. How can I enable auto email send option after placing the order through the checkout process? </p>
  
  <p>I just only want that when a user place the order from my site then an automatic email should be sent to the user email address which contain order details. </p>
  
  <p>I used from sales->order->email sent process but need to do this process automatically after placing an order by the user.</p>
  
  <p>thanks   </p>
