Lucy comes with many predefined templates. If you are not sure you have all templates you can download them. Each template can be previewed. You can preview:
To preview a template just go in the according template section (e.g. admin/settings/scenario-templates) and click the preview button for the language you desire:
The preview is fully functional. So within the preview mode you can always use the available buttons to test the functionality (e.g. use the login):
Note: In preview mode LUCY will use some dummy data for variables (e.g. "Jon Doe" for the variable %name%). You can ignore this since it will be replaced by the user name in the recipient list.
