if ($this->email->send()) {
    echo 'Email sent successfully.';
} else {
    echo 'Unable to send email: ' . $this->email->print_debugger();
}

You can then check the email logs to see if any emails were undelivered or any errors occurred during the sending process. You can access the email logs in the application/logs directory of your CodeIgniter project.

By following these steps, you can check for undelivered emails with SMTP in CodeIgniter and troubleshoot any issues that may arise during the email sending process.
