Dear Jay
I run a bilingual website, with event registration, and I use DT Acajoom Subscriber. This is how we have handled the data protection requirements and the multilingual challenge, hope this cna help you further
Re. Data Protection-Opt Out
When someone registers for our event, they have to click on the terms and conditions. Here we tell them that we need to subscribe them to our newsletter, so we keep them informed about the event. We also tell them that we donĀ“t share their information with anyone.
Second, in the email text, we include a tag (provided by Acajoom) called Your Subscriptions and another one where the person can unsubscribe with just one click.
The "your subscriptions" tag is also a link that takes them to the Subscribers Panel, where they can see which newsletters they are subscribed to, and they can also unsubscribe.
Both these things are in line with EU Data Protection guidelines.
Re. Multilingual Newsletters
Acajoom is not designed to work in multilingual environments (see their website
http://www.joobi.com
) -as I discovered, too late for my liking. they actually recommend setting up different lists for each language, so people sign up to newsletters in each language.
For us this was too complex, so since we only have two languages (English and German) we write ONE newsletter, with both languages one after the other.
You can have a look at our newsletters (using the free version of Acajoom and their standard HTML Template) here:

I hope this helps you further.
