How to send an email with Mandrill and jquery by submit contact form

It's easy to send notification email just by ajax request. Sure would be good to add some validation.
Create simple form contact.html

 <link href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css" rel="stylesheet"></link>  
 <form class="form-horizontal" id="contact">  
 <fieldset>  
 <!-- Form Name -->  
 <legend>Contact Us</legend>  
   
 <!-- Text input-->  
 <div class="form-group">  
  <label class="col-md-4 control-label" for="name">Name</label>   
  <div class="col-md-5">  
  <input id="name" name="name" type="text" placeholder="Your name*" class="form-control input-md" required="">       
  </div>  
 </div>  
   
 <!-- Text input-->  
 <div class="form-group">  
  <label class="col-md-4 control-label" for="email">Email</label>   
  <div class="col-md-5">  
  <input id="email" name="email" type="text" placeholder="Your email*" class="form-control input-md" required="">  
     
  </div>  
 </div>  
   
 <!-- Textarea -->  
 <div class="form-group">  
  <label class="col-md-4 control-label" for="message">Message</label>  
  <div class="col-md-4">             
   <textarea class="form-control" id="message" name="message" cols="6" rows="6"></textarea>  
  </div>  
 </div>  
   
 <!-- Button -->  
 <div class="form-group">  
  <label class="col-md-4 control-label" for="submit"></label>  
  <div class="col-md-4">  
   <button id="submit" name="submit" class="btn btn-primary">Send Message</button>  
  </div>  
 </div>  
   
 </fieldset>  
 </form>  
 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.1/jquery.min.js" type="text/javascript"></script></code>  

And following ajax call:

 jQuery(function($)   
 {  
   $("#contact").submit(function()  
   {  
     var email = $("#email").val(); // get email field value  
     var name = $("#name").val(); // get name field value  
     var msg = $("#message").val(); // get message field value  
     $.ajax(  
     {  
       type: "POST",  
       url: "https://mandrillapp.com/api/1.0/messages/send.json",  
       data: {  
         'key': '#PUT_YOUR_MANDRILL_API_KEY_HERE',  
         'message': {  
           'from_email': email,  
           'from_name': name,  
           'headers': {  
             'Reply-To': email  
           },  
           'subject': 'Message from Contact form',  
           'text': message,  
           'to': [  
           {  
             'email': 'johndoe@email.com',  
             'name': 'John Doe',  
             'type': 'to'  
           }]  
         }  
       }  
     })  
     .done(function(response) {  
       alert('Your message has been sent successfully'); 
       //reset input fields after successful submission  
       $("#name").val('');  
       $("#email").val(''); 
       $("#message").val('');  
     })  
     .fail(function(response) {  
       alert('Error sending message.');  
     });  
     return false; // prevent page refresh  
   });  
 });
