Need to check in with guests who have not RSVP’d to your wedding yet.
There’s really no choice but to directly ask the invitees via telephone, e-mail or in person if they are planning to attend – however, you can always solicit the help of your attendants to do the dirty work. To ease the awkward nature if these conversations, phrase your inquiry like this “Aunt Jenny, its Sara. I hope you have received our wedding invitation. We need to give our final numbers tot he caterer this week, and I haven’t received your response card, so I am calling to ask if you and Uncle John are attending the wedding. We hope you will be able to join us.” Do not point fingers are lay blame regarding their forgetfulness. After all, invitations and response cards are occasionally lost in the mail.
