Email suddenly stop working

My invoices were working fine and clients were happy to receive the emails. They even ask me about Ninja, to which I answered you must go for it etc. Today suddenly it stop functioning and I went through the forum and could not find a solution. Nothing I changed in my settings… it is frustrating after activating the company too! Do I have to make any more payment for any magic intergrations?
