Hi Djulia,
>Is it possible to add dates in placeholder (#today#, #created#...)?
It would be hard to anticipate what each user would want. I've added support for adding custom placeholders, though. You can just create a file in the plugin dir called: newsletterBuilder-custom-placeholders.php
<?php
$placeholders['unixtime'] = time();
$placeholders['today'] = "whatever you want here";
$placeholders['created'] = "whatever you want here";
?>
I'll send you an updated version with that code and it will be in the next release.
>It would be also interesting to be able to add a style in the header.
>Currently, we are obliged to add a style in the plugin.
Have you tried specifying the style in the WYSIWYG under: Newsletter Builder > Templates? Not all mail clients respect CSS styles in the <head></head>. We've updated the wysiwyg in 2.50 to allow style tags in the content.
Let me know any feedback or suggestions, thanks!
