Hello @LutherH ,
The previous way of posting to social media from our product was known as Social Share, the new and improved method is Social Post. This still offers the same functionality that the previous version did but within you now have four total platforms available to you. Three of them being Facebook, Twitter and LinkedIn that you had previously but now our new Social Post tool offers the highly requested Instagram social platform. To help get you familiar with the new tool I have included a knowledge base article that goes over the posting process here for you.
However, by no means do you have to use this new tool. The email URL link is still generated once you have sent out your email to a list. That email URL link can be copied and pasted directly within Facebook if you wish to share the campaign onto social media that way.
