    'smtp_port' => 465,
    'smtp_user' => 'yourgoogleaccount@googlemail.com',
    'smtp_pass' => 'yourgooglepassowrd',

$to = array('recipient_address@gmail.com',
           'other@email.com');
$subject = 'Your gmail subject here';
$message = 'Type your gmail message here';
// Load CodeIgniter Email library
$this->load->library('email', $emailConfig);
// Sometimes you have to set the new line character for better result
$this->email->set_newline("\r\n");
// Set email preferences
$this->email->from($from['email'], 
$from['name']);$this->email->to($to);
$this->email->subject($subject);
$this->email->message($message);
// Ready to send email and check whether the email was successfully sent
if (!$this->email->send()) {
    // Raise error message
    show_error($this->email->print_debugger());
}
else {
    // Show success notification or other things here
    echo 'Success to send email';
}
