I try for a while now to prepare my new drupal site newsletter.
For this, I installed Simplenews and Simplenews content selection modules and style my newsetter in table/td/tr mode in simplenews-newsletter-body.tpl.php et simplenews-newsletter-footer.tpl.php files, to get a better compatibility with mail clients.
But the contents of the newsletter between the body and footer templates keep the div tags generated by Drupal.
So I would like to change the template of contents but I don't find how to do it. Where can I theme the good template for this ?
