trying to upload an article to create an email. It keeps telling me it doesnt recognize the format.

Hello @L96581 ,

Make sure the document you're trying to upload is one of the accepted formats, and isn't some specialty type, or doesn't need to be properly saved / converted within the program you used to build it. Additionally, make sure the document you're trying to upload is 5MB or smaller.

For more info, please see this article.
