If I could give you advice - it would be STAMP your RSVP's and LABEL THEM! I put all the guests in an excel sheet from both sides so I could track which guests got theres sent yet. And then whatever number they were in excel, I wrote that number real small on the bottom corner of our RSVP postcards. I have received 2 so far without a name on them so now I'm beyond thankful that I did it! Also, I think we're getting a lot of RSVP cards back, both attending and not attending, because we stamped them! I would 100% recommend doing this. Such a small thing, but totally worth it. Thoughts?
Happy planning !
