Swift_TransportException error in laravel

I am trying to create a contact form that sends a message to my email address. When I checked this I got this error

Swift_TransportException

The expected response code is 250, but received the code "530", with the message "530 5.7.0" First, must issue the STARTTLS command. bv17sm3597476wib.13 - gsmtp "

This is my controller

public function contact()
{

     $data = array(
                'name' => Input::get('name')
                );


            Mail::send('emails.contact', $data, function($message){
                $message->to('test@gmail.com', 'Nikki')->subject('Login Details');
            });
}

      

        
        
        
      

    

and this is my contact .blade.php

{{ Form::open(array('id' => 'contact-frm', 'class' => 'contact-form', 'route' => 'contact')) }}
{{ Form::label('fname', 'Name') }}
{{ Form::text('fname') }}

{{ Form::label('surname', 'Surname') }}
{{ Form::text('surname') }}

{{ Form::label('email', 'Email') }}
{{ Form::text('email') }}

{{ Form::label('message', 'Message') }}
{{ Form::textarea('message') }}

{{ Form::submit('Submit') }}
{{ Form::close()}}
