Your d.vinci system comes with a couple of correspondence templates.
Over the years, we have created some examples that you are welcome to take a look at, copy the text from them into a new correspondence template and customise them for your own purposes.
Note
Please remember to press the key combination Ctrl+↑ +V simultaneously when pasting the text into a new correspondence template or to remove the formatting from Word via the [Tx] in the editor so that the text is displayed as it is set in your system. See also Copying text from Word templates.
