How to politely ask people to RSVP?

The acronym RSVP is literally a polite way to ask people to RSVP

Wait one more week and shoot out a text/facebook message.

Just text/email or whatever. I literally said "just wanted to follow up on the RSVP for the wedding" blah blah blah.

Everyone responded within a day or two with email, text or our website.

Well, I would honestly pick up the phone and call them. I would ask them for a reply by X date, if you don't hear from them they will be marked as a decline.

When was your RSVP deadline?

Once... I forgot to RSVP to a wedding (I know, I'm really ashamed about it and since, I've RSVP'd as soon as I received an invite).

The bride contacted me on FB and said, "Hi Eileen, I just wanted to check in to see if you were coming to the wedding." I was not at all offended - I actually felt terrible for putting her in that position. Don't worry too much about being pushy about it - it's a dick move to not RSVP by the expected date so they're the ones who should feel bad (again, I know I felt really bad).

I put a pin on my wedding website and then messaged everyone informing them that they'd missed the rsvp deadline but could still rsvp online by such and such date and here's the code.

If you have passed the rsvp date, contact them in the way you usually communicate with them. You can be firm and polite.

"I am calling because we have not received your rsvp for the wedding and our caterer needs the final numbers. If you are unable to commit, we will have to consider you a "no" and will miss you at the wedding."

The wording is important so that they know is their last chance. If you just ask them to let you know, some of them won't and you will be no further ahead.

I know it's not what you want to hear, but the polite way is to include and rsvp card in the invite

Call them.

And yes, as Blair wrote, the standard thing (and there are reasons for standards) is an RSVP card, with a stamp, that compels them to make a decision and let you know..

But now you have to call them.
