I have a Send Notification as part of a workflow in SharePoint 2013. This workflow step sends emails to a large group of people that is maintained on a SharePoint site via a list. I have "Send individually addressed notifications" checked. I'm running into a problem where occasionally people have left the company, and hence emailing them causes your email to bounce back. This causes the workflow to error out immediately and anyone in the distribution list after the person that caused the workflow error, doesn't receive an email. Is there any way around this? Manually auditing the distribution list isn't feasible because it's huge. Is there any way to just ignore the error on the Send Notification step and let the workflow continue?
