Sending Email using SMTP codeigniter

Question

I am trying to send email using smtp codeigniter. The code I am using is as below:

public function notify_marketing(){
    $config = Array(
                    'protocol' => 'smtp',
                    'smtp_host' => 'ssl://smtp.googlemail.com',
                    'smtp_port' => 465,
                    'smtp_user' => '[email protected]', 
                    'smtp_pass' => '*******',//my valid email password
                    'mailtype' => 'html',
                    'charset' => 'iso-8859-1',
                    'wordwrap' => TRUE
                  );

    $this->email->initialize($config);
    $this->load->library('email', $config);
    $this->email->set_newline("\r\n");  
    $this->email->from('[email protected]'); 
    $this->email->to('[email protected]');
    $this->email->subject('My Subject');
    $this->email->message('Hello there');
    if($this->email->send())
    {
        $this->session->set_flashdata("success","Email sent.");
    }
     else
    {
        show_error($this->email->print_debugger());
    }
}

However I am getting the following error in the response. I tried other solutions from this site but didn't work.

    <div id="exception_error">
    <h1><span class="type">An Error Was Encountered [ 500 ]</span></h1>

Answer 1

The code is perfect.

You need to use Application password of gmail not the gmail password. Please set a application password from gmail settings and give the password here.

It will work perfectly then. See More from HERE

Process to setting up a app password in gmail:

1. Visit your App passwords page. You may be asked to sign in to your Google Account.
2. At the bottom, click Select app and choose the app you’re using.
3. Click Select device and choose the device you’re using.
4. Select Generate.
5. Follow the instructions to enter the App password (the 16 character code in the yellow bar) on your device.
6. Select Done.

Once you are finished, you’ll won’t see that App password code again. However, you will see a list of apps and devices you’ve created App passwords for.
