So we just sent out invites (RSVPs due July 1 since the venue needs final count by July 10) and already had 4 families RSVP online using the wedding wire tool!
Heard from the guests and they apparently LOVED how convenient it was and how easy it was!! On the front of the RSVP card I wrote out exactly how their name is on Wedding Wire. On the back of my RSVP cards I wrote out instructions on how to RSVP online. It went so smoothly!
For sure recommend using the built in wedding wire RSVP if you are doing them online!
