Hello @RobK81 ,
The social share system is largely the same process when posting emails. Once you connect your accounts, simply select the social share option on the email's reporting page, add the text and imagery your want, and schedule. Social share is only available for an email after it's at least been scheduled, but the link won't be live till it's actually sent.
