How to Handle Missing RSVPs

You call/email/text/whatever asking for their RSVP. It's your responsibility to follow up with them.

You can't really cut off getting them back. I'd wait a few more days and then start making phone calls. Let them know you need to have your final guest count into your venue and noticed you haven't received their RSVP yet and was wondering if they would be able to make it. We had 40 outstanding by our due date. Called them all and they all came. People just forget to return it. Lame I know but it happens.

Follow up with them. Don't assume they aren't coming

When is your count due to your venue for the 10/1 date? If not for a while, give them some time before following up.

This is one of the problems with early RSVP dates. Another problem is that guests will RSVP yes and then cancel within the next two months. To any bride reading, don't ever make your RSVP date 2 months ahead of your wedding. This is when the invites should have been going out.

Wait a few days as some people think that the card is supposed to go in the mail on the RSVP date. Start calling/messaging this weekend. If no response to the call/message, that person can be counted and treated as a no.

My due date was Friday and there are a bunch missing too. I set up online RSVPs on our website and will start emailing/Facebook messaging this week with the link in hopes that making it slightly easier than dropping a postcard in the mail makes it happen.

Since it is kind of early (by your own admission) to have RSVPs due, I'd wait wait a few days or a week before calling. You really shouldn't need over a month for any reason. But do follow up. I used to be a bad RSVPer and not send it back because I didn't realize it mattered that much and people had to call me. Since being engaged now I understand that it determines how much food, alcohol, chairs, dishes, etc. you order and it is driving me a little crazy that so many people have not RSVPed. My deadline isn't here yet, but I'll definitely start making calls on the deadline to remind people. It drives me crazy too that people who are planning weddings or their children are planning weddings have not RSVPed. Don't they know how it is?

We called/texted all our missing ones.

Follow up, as everyone else said. "Hi! We just wanted to touch base to make sure you received the invitation to our wedding. We'd love to be able to celebrate with you." I had FOUR guests not receive their invitations.

We technically don't need a count due to our venue, its just to our renters. I wanted to plan ahead to make sure I had the rental numbers by september 1st to reduce some of the planning stress.

I've only had to facebook one person so far because they returned a blank card.

If September 1st is the date you need to turn in your first final count to a vendor, you can wait a few weeks to start reaching out.

As @BlueHenBride said, wait a few weeks. Unfortunately, you very, very rarely reduce any stress by giving an early RSVP deadline. Usually, you compound it because people don't know if they can make it/get the time off work, etc.
