These reply cards contain only a single line of text asking for a reply by a given date. Your guests are expected to write a response and indicate whether or not they will be attending your wedding, but are not selecting any menu choices or rsvping to any other events. This format is very traditional but may confuse guests that have not seen it before, and you may not gather all of the information you need. You know your guests best, so chose your response card language accordingly.
