I use the plugin on a multilingual site and it works so far very good with one single exception: if a user unsubscribes, the goodbye message won’t be tranlated so everyone gets it on the standard language.
I set up the translations for every system message on the exact same way and they work on any other case but not with the goodbye message.
Hi, yes this is exactly the problem. I receive the opt-out mail always in the standart language. Regardless in which language I subsribe. With the welcome language and other system mails works perfectly. Only the goodbye mail doesn’t have the right language.
