Is the legit?

I received a 'follow up' email today from one of the surveys I did asking more questions on the subject.I don't recognize the sender of the email but the questions that they asked in this email were definately related to one of the surveys I recently did because I recognized the specific name brand. At the end of the follow up sirvey email they requested my address to mail my rewards check to..Does this sound weird?
