Our guests have three different ways to RSVP -- old fashioned card, online, or via phone, yet one day before the deadline and we're still missing 15 responses. Now, it isn't considered rude when your bank reminds you that your credit card payment is due, or anyone else reminds a person of other deadlines, so why is it considered rude to send out a reminder letting people know that the RSVP deadline is tomorrow? At this point, I feel like most of those 15 probably forgot, so why wait until they have actually completely missed the deadline and embarrass them? That being said, I can completely understand why sending multiple reminders is annoying and unnecessary, but one reminder of the deadline so that we don't need to track people down? Is that really all that rude?
