If necessary, you can rename and delete the fonts you have uploaded.

Fallback Font
If your users do not have the selected custom font in your design, you can also set a fallback font for the custom fonts you upload.

The fallback font is applied to any font (i.e., standard, non-standard, custom fonts) in the HTML editor and Drag and Drop Editor.

You can select the font letterform that will be selected as a fallback font for the email recipients who don’t have the fallback font you have selected.
