$config = array(
    'protocol' => 'smtp', // 'mail', 'sendmail', or 'smtp'
    'smtp_host' => '', 
    'smtp_port' => 465,
    'smtp_user' => '[email protected]', //here is your email
    'smtp_pass' => '12345!', // here is your password
    'smtp_crypto' => 'ssl', //can be 'ssl' or 'tls' for example
    'mailtype' => 'text', //plaintext 'text' mails or 'html'
    'smtp_timeout' => '4', //in seconds

    public function __construct() {
        parent:: __construct();


    public function index() {

    function send() {
        $from = $this->config->item('smtp_user');
        $to = $this->input->post('to');
        $subject = $this->input->post('subject');
        $message = $this->input->post('message');


        if ($this->email->send()) {
            echo 'Your Email has successfully been sent.';
        } else {

Here is,

  • $this->load->config(’email’); loads the email configuration settings
  • $this->load->library(’email’); loads the email library
  • $from = $this->config->item(‘smtp_user’); gets the sender id from the email configuration file that we defined.
  • $to = $this->input->post(‘to’); gets the to value from the submitted form
  • $subject = $this->input->post(‘subject’); sets the email subjected from the form
  • $message = $this->input->post(‘message’); sets the email message from the form
  • $this->email->set_newline(“\r\n”); defines the new line characters for emails
  • $this->email->from($from); sets the sender email address
  • $this->email->to($to); sets the recipient email address
  • $this->email->subject($subject); sets the email subject
  • $this->email->message($message); sets the email message
