Our RSVP By Date is a Few Days a Way and We’re Still Missing Responses. How and When Can We Find Out Who’s Coming?
I would wait a few days past the RSVP date listed on the reply card before you call or email guests who you haven’t heard from yet. It’s okay to divide the list: Ask your mom and his to reach out to relatives and their friends and you and the groom contact your friends.
When you’re asking don’t be accusatory, be casual about it and say that you didn’t hear back from them and you’re hoping they can make it.
