Question
In the notification template there are placeholders like @@Header@, @@Footer@, @@Style@. How to change the content displayed by these placeholders?
Answer
These are subtemplates, which can be found in the list of the notification templates (search by Template Name). They can be edited the same way as ordinary templates, just keep in mind that they can be used in several notification templates, the changes will be applied to all the templates this subtemplate is used in.
