I am trying to send HTML emails with Codeigniter's email class. This is how I am doin开发者_StackOverflow社区g it:

    $config = Array(
        'protocol' => 'smtp',
        'smtp_host' => 'ssl://smtp.googlemail.com',
        'smtp_port' => 465,
        'smtp_user' => 'a@a.com',
        'smtp_pass' => 'password',
        'mailtype'  => 'html', 
        'charset'   => 'iso-8859-1'
    );
    
    $this->load->library('email', $config);
    $this->email->from('b@b.com', 'Me');
    $this->email->to($email); 
    $this->email->subject($subject);
    $this->email->message($html);
    $this->email->set_newline("\r\n"); 

    if($this->email->send()){
        return true;   
    }else{    
        return false;
    }

However, when I view the email in Gmail or outlook, I see bunch of HTML appearing as text at the top of the email and the rest of the email is displayed normally.

Here is the HTML I am sending, its a template that I found to test with. Lines 1 to 19 appear as normal text and is not rendered.

This is how the email looks.

Why is this the case?

As a summary of our conversation in the question's comments, the problem appears to be the content of the $html variable. The variable contains entity encoded HTML. Running it through html_entity_decode solved the problem.

HTML code not rendered seems to be the header of your template. Maybe Gmail will display only the code found inside the tag body, since Gmail is a web application, so it's displayed in a webpage already containing a header and a body (<html><head><body>).
