Hi @Meghan Wilson-Smith,
Thank you for posting in this community.
I'm not quite sure what you want the email news digest to look like in two languages.
However, at this time, SharePoint Online does not have the ability to specifically set the language of the message, but you can enter two languages in the optional information section of your email news digest.
We are always looking for ways to improve SharePoint, and your feedback and suggestions are very valuable.
We suggest that you can make suggestions on this SharePoint Feedback portal for creating a bilingual email news digest in one email. Your contribution will be highly appreciated.
