I added templated email functionality.
You can configure a directory that allows you to add custom email templates and wording and still leverage replacements/templating for hostname, handle, verify link etc. There is a fallback config if you do not want to configure every locale, and just have a specific target audience. It will yell at you if you miss a template for the locale. Maybe it could be made to be more flexible. I like fail fast deployments. I proved it worked for my fileorbit.cloud instance.
