We serve customers with multiple languages, even within a same Company (offices in multiple countries, multilingual countries or provinces/states) which means that a Dispatcher rule based on domain or Email would be useless. However, since each contact can pick its favorite communication language, allowing the Dispatcher's rules to be able to case on the contact language parameter would offer a much more flexible solution when it comes to sending notification messages, in the language selected by the end-user.
Thanks for considering this feature.
