Hi y'all! I'm trying to decide if I should have an online option for guests to RSVP on our wedding website. We would still mail out RSVP cards (addressed and stamped) for guests to return through the mail as well. I think it would be a good idea for the younger guests to RSVP online or for anyone that finds it quicker and easier than mailing back the card. However, my mother is worried that we would be wasting the money and energy on stamps and everything for the paper RSVP if the majority decide to RSVP online instead. Do you think it's worth it to do both? Thanks in advance!
