I would like to use others fonts then the ones in the dropdown in the DS Editor. We have a special corporate font.
How do I do that?
In the template editor we have chosen to add only fonts that are common and will work across all platforms. The Microsoft platform is not the only one present on the internet.
If you choose a font that is not present on the recipients computer, that client will display your mail in whatever is the default font, in all likelihood Times New Roman.
The best practice approach to using other fonts is the use of families. A family is a list of font to use in priority. So if the preferred font is not present, then you can advice on the next best choice.
Here is an html snippet showing how to use a font family:
<span style="font-family:Calibri, Verdana, Arial">Text</span>
You can apply this if you go to the source code view in the template editor, and then manual change the font definition.
Tip: When I design a template, I usually make it like I want it using Ariel. And when I am done I go to code-view and substitute the style there with a font-family style that I have prepared in Notepad.
