When a journey is created from a template, some of its content is editable by the user. What actually can be modified by the user is defined on template level through the locking of components. The user can modify
- Email header fields and constraints when unlocked
- Edit unlocked content components, no layout or constraints however
- Add new content components to a placeholder
- Create new links
- Fill out variables when they exist in the template
- Add items to the repeaters
