Hello @ErinM676 ,
I would recommend calling into our Deliverability team. They're likely have better insight regarding these domains, and in regards to which type of bounce occurred for them.

Well for my last two newsletters I've had nearly 50% bounce rate but I can't connect with Constant Contact so the problem continues. Very disappointing and frustrating. Today's bounce was 346 our of 714.
