The deadline for our wedding RSVP has now passed, yet I have not received your response.
Please do not assume that I 'know' you are coming. Afterall I did not assume that you 'knew' you were invited. I took the time to send you an invitataion complete with a self addressed stamped response card and evelope.
If I 'knew' you were coming I would have saved myself the cost of the stamp, don't you think?
Please respond even if you are not coming. The 'no' RSVP is just as important as the 'yes' RSVP. I need an accurate headcount for the caterer.
And, finally please mail back the card even if you told me that you were coming. It makes it easier to do the table seating, and to get the accurate aforementioned headcount.
With that said, I look forward to opening my mail box this week and seeing your very special RSVP in there waiting for us.
