Magento – Add custom font-family to magento email template

The template is not aware of the email template that is calling it.
If your template needs to look differently based on the e-mail, you need to use 2 templates for 2 different emails.
I mean instead of using in both of them

 {{layout handle="some_handle_here"}}

in both of them, you need to use in the section one something like this:

 {{layout handle="some_other_handle_here"}}

and create the new layout handle in one of your layout files and use a different template file.

Ok :) "Bad line gap " error indicates the use of one deprecated browser prefixes like: white-space: -moz-pre-wrap which isn't required as of Firefox 3.0 You have to inspect your font stylesheet on the line 2 to see exact prefix. After line :

font-weight:

/remove or comment out this code line (-moz-something)/

And see if it helps.
