No RSVP? You aren't getting in

If a guest received an invitation but did not RSVP by the RSVP date...then that makes them an uninvited guest?

Just call or text people.

That's hilarious MrsFuture

Hey thanks OP, for editing your post and essentially shouting to us that you want to put a stern note ON THE INVITATION. The answer is still no. It's rude. You'll simply need to follow up with those who haven't responded. Look around at invitation samples have you ever seen such wording? No? That's because people don't do it.

We will have bouncers...They are nice bouncers

Great, so you'd actually have Aunt Gladys bounced right out of your wedding because of a communication snafu? That's sweet.

The purpose of the bouncers is...?

a) To refuse anyone who was INVITED but did not respond in time

b) To refuse anyone who was NOT INVITED

c) To incite intimidation for your guests

No Panda Please. Uninvited guest are just that. Folks that heard about our wedding and showed up. We know too many people. Everyone can't come

You have never seen security at a wedding? Security/Bouncers?

MrsD17 Aunt Gladys is good. Thanks! She is coming and she will RSVP. No need to kick her out.

Hi Kellye - if you're really concerned about large amounts of uninvited guests showing up at your wedding, then there are some extra steps you can take. I'd be very careful to not talk about your wedding plans or share any wedding details with anyone who is not invited, keep the wedding talk to a minimum on social media, password-protect your wedding website, and absolutely have assigned tables or seating.

It should be abundantly clear to anyone that if they do not receive an invitation, they are not invited. An extra hint is if their name is not anywhere on the seating chart, or they don't have an escort card.

If you truly think bouncers are necessary then that's your choice! I can't imagine physically removing someone from my wedding, but I'd also never dream of showing up to an event I was not invited to.

I have seen security at a wedding. I have seen security at other non-wedding events as well. Pretty clear on what security is supposed to do at an event that requires crowd control and especially entry.

What was not clear was whether a guest who for you sent an invitation would be considered "not invited to the wedding" if no response was received from them. I understand the need to keep people out that you did not invite, but it just seems a bit sad for a guest to be turned away due to miscommunication if that's what you're going for. If not, then awesome sauce.

As much as I want to do this (as I am dealing with all the stragglers) I wont. Call them if they don't RSVP. If they are decent people, they will feel some sort of guilt for not RSVPing on time. Or at least they will when they plan their own wedding. I doubt anyone doesn't RSVP to a wedding on purpose.

My one sister didn't rsvp to my other sisters wedding. She showed up and wasn't on the list so she didn't have a reserved seat . The venue was going to fix it by just adding another chair and table setting at the immediate family's table , but by then her feelings were hurt and she left after the ceremony. It caused a lot of unnecessary drama . I would follow up with your guests via phone .

I like the all caps edit.

It's in poor taste/impolite/rude to mention on the invitation as to who isn't invited and/or won't be allowed admittance.

There's no way to do it that won't come across as rude. Sorry.

You need to just be vigilant on obtaining concrete answers from those you haven't heard from. Wait a few days (a week if you can) after the "RSVP by" date, because some people send their RSVP in the day that it's due, and make some phone calls.

Also, don't post about the wedding on social media and don't talk about it in front of those you don't plan on inviting. That will decrease your chances of people inviting themselves.

Yea..we aren't post anything about our wedding on social media. Folks do that and it sometimes gets out of control.

If all else fails get someone to dress up at Gandalf and stand at the front of your venue

I think you still have to let guests that you invited in even if they didn't RSVP. Make sure you have a place card available for them as well. I particularly like this one.

I like the chair and sandwich idea lol

That's just how RSVPs work. No need to spell out social norms (that makes YOU the rude one!)
