How can one post a campaign/email newsletter to a private Facebook group that is not-for-profit?

We have no need or use for a "business page." We simply want to easily post our mailings to our private Facebook group for a non-for-profit organization.  Thus, we have no "business page."  Yes, we could manually paste a link to the home page of the group. Is that the only way?  Thank you

Hello @JaneMG ,

Due to API restrictions from Facebook, only business pages can be posted to from 3rd party software such as us. To post to standard group pages or personal pages, you'd need to manually do so from the platform itself. If you have feedback regarding this, we'd advise reaching out to Facebook's support.
