Hi Heidi,
The Feedburner emails are pretty basic. For nicely formatted e-newsletters try using a service like http://www.nouri.sh. Their wordpress widget allows users to subscribe easily. You also get a lot more control over the look and feel of the delivery of your content. I can’t recommend it enough, it added 10% traffic to my website.
Hope that helps.
Thanks, much appreciated, If you need some assitance with updating the template just let me know and I’ll provide some free (professional) french translation.
You may also be interested to take a look at this plugin, which enables your blog to be multilingual, even if you don’t have professional translators, it integrates with third party API’s to use a paid for service.
Hope that helps.
