Today was our wedding RSVP deadline and we still have 70+ people who have not submitted their RSVP. We did not have paper RSVPs, just RSVPing through the knot website. I have looked all over the website to find where I could send out a mass text to guests who have not responded and could not find it. I also googled this and had no luck. I saw someone did this for a wedding we attended, so I know it is possible. Can someone please let me know how to do this? Thanks so much!
