Magento 1.9 sendTransactional() doesn't include CSS from email template

Question

I'm using sendTransactional() to send emails programmatically. All working fine besides the following line in the email template is not included

  {{inlinecss file="email-inline.css"}}

Any fixes?

Answer 1

I found it out. It has to include ->setDesignConfig()

So the following code will include CSS file when sending out emails with sendTransactional().

    Mage::getModel('core/email_template')
        ->setDesignConfig(array('area' => 'frontend', 'store' => $storeId))
        ->sendTransactional($templateId, $sender, $recepientEmail, $recepientName, $vars, $storeId)
    ;
