Email Template

Hey Guys, 

I'm relativly new in CI4 and im having problem with my email sending.

We have different emails we want to send from our website. Its working good the email are going out. But now we don't want to just send a email we want to have a template around the mail.

So I created a emailhead.php in the app/view folder and also a emailbody.php in the same folder and I just want to load it into my controller before the actual message.

I tried to do

Code:

$message = $this->load->view('emailhead.php');
$message .= 'The text of the email';
$message .= $this->load->view('emailfooter.php');

But I allways get an error 

ErrorException

Undefined property: App\Controllers\Email::$load

I appriciate all of your help, thanks
