Sorry, i have this question:
now i have docman but i will change with your product.
i have a category, the files in this category are download previus login from frontend for a joomla group of user (example: 250 user in this group)
when i add new file in this group from backend (or dropbox/googldrive/onedrive sync) can send automatically an email to 250 user that inform this to new file is present and in the email there are the title of file (not filename), category, and url
thanks a lot
