Embedding blog posts from a newsletter platform

Hi! I am helping a client uses Flodesk for their newsletter platform. The client wants to embed previous issues of the newsletter into their website to serve as a kind of blog. Is there a native way to do this? Flodesk doesn't seem to have RSS capabilities, and Squarespace doesn't seem to be able to import newsletter content from other platforms. If it's not possible, do you have any ideas for a sustainable workaround?

Thanks!

I'm looking for a way to do this, too. I'm hoping this gets some attention with my commenting on here. However, if I figure it out, I'll let you know.
