What Comes After The M On Wedding Reply Does Returning A Wedding Reply Card Without Checking Yes Or No Mean Anything?

Does returning a wedding reply card without checking yes or no mean anything? - what comes after the m on wedding reply

We did not send wedding invitations with response cards in your name and brand can participate, fill or fill in the number of people coming. We have another if the person has fulfilled his name, but do not check the possibilities. I think they probably just overlooked or forgotten, but I just wanted to make sure that he did not say something like "maybe" or "ask again later." Thanks for your help!
