HTML emails sent as plain text

Looks like you have alternative message set:

Code:

$this->email->set_alt_message('This is the alternative message');

Remove that line. Gmail is showing the plain text part for you. Not sure it that's the default or what, but that appears to be your problem.

EDIT: Ah, sorry. I see now that the HTML part is showing as plain text. That's strange considering the mime type clearly shows text/html. Hmmm...
