Can I force html with every email?

[linnx]

These comments are irrelevant to the question being asked. I asked how I can change it, not for the reasons why we should not do this.

Zen Cart is a customizable solution where I can customize it for my needs. And I have a need to send html email.

I am getting somewhere in case anyone wants to change it.

Find includes/functions/functions_email.php

And find

if ($customers_email_format == '' && ADMIN_EXTRA_EMAIL_FORMAT == 'HTML' && in_array($module, array('newsletters', 'product_notification')) && isset($_SESSION['admin_id'])) {
$customers_email_format = 'HTML';
}


I will modify the above and see how this works. After I test it, I'll post back and let everyone know if it worked or not.
