by StacylikesSparkles » Jul 13, 2012 We mailed out all of our invites on Wednesday and we did half of the RSVP's with a mail-back card and half the RSVP's with an email/phone contact response card. I've already gotten 10 RSVP's!! I feel fabulous about this choice and super efficient! We saved the mail-back cards for people we don't normally interact with via email and for the older crowd. YAY!!!
