In Magento 1.9.1 the email setup/building process was changed and the email templates are responsive.
In my case, my template email was not working, it was neither loading header nor footer, just appears that:
{{template config_path="design/email/header"}}
{{inlinecss file="email-inline.css"}}
{{template config_path="design/email/footer"}}
Then I updated my Magento store and it was working, but appeared many bugs in my Magento store so I replaced some updated folders and files with some old ones, then my Magento store worked again but the email template didn't load the header and footer, somebody knows what it can be?
