To save a template, go to the Compose page, click the little
⋮ menu button beneath the editor and select Save as template.
This will add the current text in the editor to your user template collection.
To use the saved template, simply click on the Use Template button in the User templates tool.
If this tool is not located underneath the editor, you can find it under the Tools tab in the right side pane.
If you have multiple templates saved, you can either look though them by clicking on the left and right arrows, or you can click on the expand symbol to have an overview of all your templates.
To edit the template, head over to the Assets page and click the User
Templates menu.
From here you can edit all your templates.
Here you can also use or delete templates - or create new ones.
