1. Create a guest list in Excel/Numbers and number the backs of the cards so they correspond with your list. If a card is returned with no name, this is an easy way to figure out who replied
2. Write in the number of guests invited (example 2 invited) so guests clearly understand two people have reserved seats (see example below to help manage headcount)
3. Give yourself enough time to call guests who haven't responded
4. Offer your guests a second option such as on-line RSVP'ing via your wedding website
