What is the best way to send an email after you've filled in the form succesfully, but before the onsucces redirect?

Code:

$this->form->submit('send')
->model('form/form_model', 'do_db_stuff')
->onsuccess()

Should you do it in the model?
Or like this?

Code:

$this->form->submit('send')
->model('form/form_model', 'do_db_stuff');
$this->send_mail();
$this->form->onsuccess();

Is it possible to add an error to the form in another method in the controller?

Are there any other possibilities to handle the email?

What is the best option to go with?
