Email template header and footer not working

[lpiragine]

I have a template for my email attachment that has header and footer, but on the second page it doesn't show the header, and the footer it's on the middle of the page. What am i doing wrong? Is it because i have images? 

This is the template:

And this is how it's showing:

As told by @Phil, headers and footers (among other things) are not supported
