We have a mail template and massively using Joomla Article add-on.
The add-on use H2 for article title.
We have set H2 title with Arial/18px/specific color in global parameters, the preview is Ok but the test inbox (tested in webmail and thunderbird) get a H2 with Helvetica, black and 30px style.
Settings are overrided only in article part not in a text block with a H2 inside.
Where our settings are overrided ?
