Hello Mailman & welcome to our forums!
That's a very good point. We'll do that in the next version.
What would be most suitable in your opinion? H1 or H2 tags around the title? Something else?
Kind regards,
Pete
EDIT: If you don't want to wait for an official update you can edit the file /wp-content/plugins/chimpexpress/compose.php
Replace line 595 with:
Code:
$js .= "posts['".$p->ID."'] = '<h1>".esc_attr(urlencode($p->post_title))."</h1>".esc_attr(urlencode(str_replace(array("\n"),'',$p->post_content)))."';\n";
(You can modify H1 in that code to another H tag.)
