Hi @Tom White33,
We do include part of the content in under most of the actions in email notifications. It is included when someone comments, replies, or answers a post or question. Also when someone likes a content.
We are extending this behavior to all content types and other actions as well. For instance, right now when a new discussion or article is created, we just mention the title in the email notifications. Soon, the first paragraph of the discussion/article will be included as well.
