This morning two unique emails are being sent to two smallish (<800 people) audience and they still have not “sent” yet. I recreated one because even after an hour it still hadn’t sent. Has anyone run into this before, and if so, what was the cause and how did you fix it? 

I have reached out to support but wait time on that is 4 hours and I am already outside of my ideal window for when we wanted these emails to be sent.
