Replacing tokens in Newsletter I'm trying to create a custom template using the Drupal Newsletter module. 

I need to populate the newsletter with existing content. For this, I think I need to replace a token like [node:nid] in the newsletter body (which is created with CKEditor). However, I have been unsuccessful. 

When I use the token filter module, I'm only able to replace global tokens like date or [site:url] and not tokens involving a node. Can someone please help me out?
Tokens are contextual based on where they are used, so it's not possible to reference arbitrary content. If you can add fields to the newsletter, the ideal way to resolve this would be to add a node reference field, then create your tokens by doing something like [newsletter:field_node[0]:entity].
