Hi, just a question here regarding best practice.

Lets say a user signs up and if it's successful, the user receives an email.

My question is, do i put the email codes in the model or the controller?

Code:

$this->load->library('email');

$this->email->clear(TRUE);

$this->email->to($reg_email);
$this->email->from('[email protected]', 'Tester');
$this->email->subject('Test');
$this->email->message('Test Mail...');
$this->email->send();
