@scottalanmiller You did nothing but jump to an illogical conclusion. I believe it's more likely that this was a user error. We don't know because the OP hasn't provided enough details. What email address did he use? Did the email truly bounce or was it rejected for some other reason?
Do you always assume that a company is out of business when you read an unverified claim that an email bounced? Do you always jump to wild conclusions before performing any due diligence? I would hope not... because that isn't very professional.
